Production AI agents, custom software, and audited blockchain systems on a fixed scope. Markdown versions of every page are available at the same path with .md (homepage: /index.md). --- # Blockchain & AI Engineering for Fintech | LBM Solutions URL: https://www.lbmsolution.com/ # We build production blockchain and AI systems for fintech and SaaS teams Blockchain and AI engineering since 2014. Senior engineers only. Audit-first delivery. We stay through launch and beyond. Most engagements ship in 6 to 12 weeks, and you own the code. Book a 30-minute architecture review: we review your project, suggest the right approach, and give you a price range. No sales pitch. If we are not the right fit, we will tell you who is. Reviewed on Clutch, GoodFirms, G2, and Trustpilot. ## What we build - **Smart contract audits.** We audit Solidity and Rust contracts before they hold real money. Manual review plus Slither, Mythril, Echidna, and Foundry. You get a findings report with severity ratings, fixes, and a re-audit. - **Blockchain engineering.** Production systems on Ethereum, Base, Arbitrum, Optimism, Solana, and Polygon. Tokenization and RWA (ERC-3643, ERC-20, ERC-721, ERC-1155, ERC-4626), DeFi protocols, exchanges, and stablecoin payment rails. Most builds ship in 6 to 12 weeks. - **AI agents and automation.** Multi-agent systems built with LangGraph, CrewAI, and LangChain, with observability so you can see what the agents are doing. Deployed for support, sales ops, and data extraction. Custom software, CRM engineering, and white-label products are also part of what we do. Ask us on the call. ## How we work - **Senior engineers only.** No junior teams learning on your budget. The people who scope your project are the people who build it. - **Audit-first.** Security is not a phase at the end. We review architecture before we write production code, and we audit before anything goes live. - **We stay through launch.** Most vendors disappear at handoff. We are there for deployment, the first incidents, and the months after, when production fires actually happen. - **You own everything.** Your code, your repos, your IP, from day one. NDA on request. ## Who we build for - **Fintech.** Payments, lending, neobanks, and crypto-native infrastructure. - **B2B SaaS.** AI features, agent systems, and platform engineering for scale-ups. - **Web3 protocols.** DeFi, tokenization, exchanges, and the audits that keep them safe. ## Questions buyers ask - **Who owns the code and IP?** You do, from day one. Your repos, your contracts, your IP. We sign an NDA before discovery on request. - **Do you audit before launch?** Yes. Audit-first is how we work. For contracts handling real funds, we run manual review plus Slither, Mythril, Echidna, and Foundry, deliver a severity-rated findings report, and re-audit after fixes. - **What happens after launch?** We stay. Deployment support, monitoring, and a defined response window for production issues. We agree the SLA in the scope, not after something breaks. - **Who is liable if a contract has a bug?** We carry responsibility for the work we audit and ship, within terms we set out in the engagement. We will walk you through exactly what we stand behind before you sign. - **How fast can you start?** Discovery usually starts within days of the architecture review. Build kicks off once the scope is signed. ## Your roadmap could move next week One 30-minute architecture review. We look at your project, suggest the right approach, and give you a price range. No sales pitch. If we are not the right fit, we will tell you who is. No obligation. NDA on request. --- # About LBM Solutions | Blockchain Engineering Team URL: https://www.lbmsolution.com/about # We build blockchain infrastructure for teams who can't afford to get it wrong Funded fintech and protocol teams come to us when the thing they are building has to hold real money on day one. We are senior engineers, audit-first, with delivery out of India and client teams in the US and the UK. ## Our story LBM Solutions began in 2019 because too many blockchain projects were being shipped by teams who had never carried one to mainnet. Founder Rampawan Kumar Singla had watched good ideas fail, not on the idea but on the engineering. A consensus bug found too late. An unaudited contract drained. A vendor gone at handoff. Most teams do not need to be told blockchain is the future. They need someone who has shipped it before. Someone who will tell them what not to build, and will still be there when the first incident hits production. That is the company we built: small, senior, and accountable for the work after launch. Rampawan Kumar Singla, Founder and CEO. ## How we operate - **Seniors only, on your code.** The engineer who scopes your project is the one who builds it. Fewer people, more accountability. - **Security is the product.** For systems that hold real money, we threat-model before we write production code and audit before anything goes live. - **Fixed scope, plain English.** A written scope and a price before you commit. You own the code and the IP from day one. ## The people who do the work The senior team behind the engineering, with profiles you can verify on LinkedIn. Not a bench of contractors. - **Rampawan Kumar Singla, Founder and CEO.** IIT Delhi. Also founded WorksBuddy and Teqo Solutions, and chairs the FICCI CMSME Punjab committee. - **Manjit Parmar, Chief Technology Officer.** 15+ years in software, at LBM since 2019. MCA, certified in building with Claude, agent skills, and MCP. - **Parth Panchal, Senior Full Stack Engineer.** 6+ years building production web applications on MERN and Python Django. MSc Computer Science, Kurukshetra University. - **Deepak, Senior Flutter Developer and Team Lead.** 4+ years building production apps with Flutter, Firebase, and Web3. BTech, Punjab Technical University. - **Aman Kumar, Business Development (UAE).** Builds acquisition systems and partnerships for growth-stage clients. Based in Dubai, covering the UAE market. MBA, Chandigarh University. - **Deepali Pandit, Senior HR Manager.** Owns talent, performance, and compliance. 8+ years in HR, POSH-certified. MBA in HR. - **Shreya Narula, Project Coordinator.** Keeps SaaS delivery on track across product and engineering. MBA, LM Thapar School of Management. - **Bhanu Sharma, Growth and Execution Manager.** Bridges product, engineering, and go-to-market. Background in startup incubation and product management. BTech IT, Chitkara University. ## Where we are - **Mohali, Punjab, India (HQ).** Engineering and delivery. Where the systems get designed, built, and audited. - **United States.** Client and sales, close to North American founders. - **United Kingdom.** Client and sales, covering UK, EU, and Middle East time zones. ## Who we build for We work under NDA, so most engagements are described, not named. Series A fintech in Singapore. DeFi protocols in the UAE. Tokenization platforms in the UK. Payments infrastructure in the US. Funded teams, serious systems. ## Two ways from here No forms, no pressure. Book a 30-minute call with an engineer, or look at the work first. Whatever helps you decide. --- # AI Agents & Workflow Automation | LBM Solutions URL: https://www.lbmsolution.com/ai-agents-and-automation # Automate the work your team should never be doing by hand We build production AI agents that survive real workloads, not slick demos that break on edge two. Multi-agent systems with observability, guardrails, and a human in the loop, built on LangGraph and CrewAI, live in 6 to 12 weeks. [Book an automation assessment](/contact). We map which of your workflows are worth automating and model the real hours and cost they take today. ## First, we find out if automation is even worth it for you Before we build anything, we run an automation assessment. We look at the workflows your team repeats every day, measure the hours and cost they take now, and tell you which ones are worth automating and which are not. You leave with a short written map: the candidate workflows, the expected time saved, and a rough payback period. If nothing clears the bar, we tell you, and you have lost nothing but 30 minutes. [Book an automation assessment](/contact). 30 minutes. You keep the automation map either way. ## Where agents earn their keep Each workflow below comes with the signal that it is a good automation candidate. If a workflow matches the signal, it is worth a closer look. - **Customer support triage.** High volume, repetitive questions, clear knowledge base. Agents draft and resolve, humans handle the hard 20%. Signal: high volume plus a clear knowledge base. - **Sales and revenue ops.** CRM hygiene, lead research, follow-up drafting, meeting notes turned into actions. Signal: repetitive steps plus structured systems. - **Document and data extraction.** Invoices, contracts, KYC packets, and forms turned into structured data. Signal: high volume plus consistent formats. - **Internal research.** Pulling, comparing, and summarizing across many sources and tools. Signal: many sources plus senior time spent. - **Back-office workflows.** Multi-step processes that hop between systems and currently need a person to babysit them. Signal: multi-step plus cross-system handoffs. The pattern is always the same. High volume, rule-heavy, and currently eating senior people's time. If that describes a workflow, it is a candidate. ## Anyone can demo an agent. Almost nobody ships one that survives. A demo works once on a happy path. A production agent runs thousands of times against messy reality. The difference is everything we build that you never see in a demo. The demo is 20%. It works once on the happy path. The other 80% is the production work: - **Observability.** Every agent run is traced, logged, and inspectable with Langfuse or LangSmith, so when something goes wrong you can see exactly where, not guess. - **Evals.** We test agents against real cases before and after every change, so an improvement cannot quietly break what already worked. - **Guardrails.** Input and output validation, PII redaction, and hard limits on what an agent is allowed to do or spend. - **Human in the loop.** Confidence thresholds route the uncertain cases to a person instead of acting wrong with confidence. - **Cost control.** Token and tool-call budgets, caching, and model routing, so the agent is cheaper than the work it replaces. The demo is the easy 20%. The other 80% is why most agent projects quietly die in a slide deck. We build the 80%. ## How an agent actually works A production agent loops: it perceives the task, plans steps, calls tools and APIs through function calling and MCP, checks its own work, and either finishes or escalates. Memory carries context across steps, orchestration coordinates multiple agents when one is not enough. We design that loop for your workflow, then wire it to your real systems. The loop: perceive, plan, act (tools, MCP), observe, then resolve or escalate. Observe loops back to plan, and low confidence routes to a human. ## From assessment to live agents - **Assessment, week 0.** We map and cost your workflows and pick the highest-ROI candidates. Output: a written automation map. - **Pilot, weeks 1 to 4.** We build one agent or workflow end to end, with observability and evals from day one. Output: a working pilot on your real data. - **Harden and expand, weeks 4 to 10.** Guardrails, human-in-the-loop, and integration with your stack. We expand to the next workflows. - **Run and improve, ongoing.** Monitoring, evals on every change, and tuning as your processes shift. Most teams have a useful pilot live in 4 weeks and a hardened system in 6 to 12, depending on workflow count and integration complexity. ## Recent work - **Multi-agent workflow automation.** Industry, region, workflow, approach, and measured outcome to be confirmed with delivery. [NEEDS-VALIDATION: founder]. Anonymized references available under NDA. - **Production agent system.** Industry, region, problem, approach, and measured outcome to be confirmed with delivery. [NEEDS-VALIDATION: founder]. Anonymized references available under NDA. References available under NDA. We link each engagement to a full case study once the client approves disclosure. ## Frequently asked questions **Will agents replace our team?** No. They take the repetitive 80% so your people do the judgment work. The human-in-the-loop design keeps a person on the cases that need one. **How do you stop agents from doing something wrong?** Guardrails, hard action and spend limits, confidence thresholds that escalate to a human, and evals that catch regressions before they ship. **Which frameworks and models do you use?** LangGraph and CrewAI for orchestration, Langfuse or LangSmith for observability, and we choose the model per task across OpenAI, Anthropic Claude, Google Gemini, or open-weight models. We are not locked to one vendor. **Can agents use our existing tools?** Yes. They connect to your systems through APIs, function calling, and MCP. The agent works inside your stack, not beside it. **What about our data?** We design for your privacy requirements, including self-hosted or VPC deployment and no-training agreements with model providers. See the data section on generative AI development at /generative-ai-development. **Who owns what we build?** You do. NDA on request. Building something generative instead?

Senior engineers, audit-first, building since 2014. We design, build, and audit DeFi protocols, tokenization, stablecoin rails, wallets, and exchanges for fintech and Web3 teams. Trusted by fintech and Web3 teams across 18+ countries: Chainml, Concordium, Tarality, Coinccino, OmoSwap, Seedx. Reviewed on Clutch, GoodFirms, G2, and Trustpilot. ## What we are, and what we are not Plenty of shops will spin up a token over a weekend and disappear after launch. That is not us. We are the team founders bring in when the thing they are building holds real money, faces a regulator, or cannot afford an exploit. What that means in practice: - **We are engineers first.** Senior people who have shipped to mainnet, not a sales team with a contractor bench. - **We are audit-first.** Security is designed in from week one and audited before anything goes live, not bolted on after. - **We are not a retail crypto shop.** We do not do meme tokens, pump projects, or make me the next Shiba Inu requests. - **We stay through launch.** We are there for deployment, the first incidents, and the months after, when production fires actually happen. ## What we build Six capabilities, six pages. Each links to its full page. Lead capabilities: - **Smart contract audits.** Senior auditors, multi-tool coverage, fixed-fee scope in writing. See `/smart-contract-audits`. - **Tokenization and RWA.** Compliant tokens for real estate, private credit, funds, and invoices, on ERC-3643 and ERC-1400. See `/tokenization-and-rwa`. - **Stablecoin payment rails.** B2B crypto checkout and payouts with same-day settlement. See `/stablecoin-payment-rails`. - **DeFi protocol engineering.** Lending, AMMs, perps, and yield, with mechanism design done properly and audited before mainnet. See `/defi-protocol-engineering`. Also build: - **Crypto wallet development.** Multi-chain, MPC, and account-abstraction wallets. See `/crypto-wallet-development`. - **Crypto exchange development.** CEX, DEX, and P2P for licensed operators. See `/crypto-exchange-development`. ## How we work The firm-level operating model that applies across every service. - **Senior engineers only.** The people who scope your project build it. No juniors learning on your budget. - **Audit-first delivery.** We design for security from week one and audit before launch, using Slither, Mythril, Echidna, Foundry, and manual review. - **You own everything.** Your code, your repos, your keys, your IP, from day one. NDA on request. - **Fixed-fee discovery first.** You get a written architecture and price before committing to the build, so there are no surprises. ## What we build on Only the tech we have shipped. - **Chains:** Ethereum, Base, Arbitrum, Optimism, Polygon, zkSync, Solana, Near, Aptos, Sui. - **Languages:** Solidity, Rust, Move. - **Token standards:** ERC-20, ERC-721, ERC-1155, ERC-3643 (T-REX), ERC-1400, ERC-4626, ERC-4337, BEP-20, SPL. - **Security and audit:** Slither, Mythril, Echidna, Foundry, Certora. - **Integration and data:** wagmi, viem, RainbowKit, WalletConnect, The Graph. - **Oracles:** Chainlink, Pyth. - **Identity and compliance:** ONCHAINID, Sumsub, Jumio. ## Who we build for - **Fintech.** Payments, lending, neobanks, and crypto-native infrastructure for Series A to C teams. - **B2B SaaS.** Blockchain features and platform engineering for scale-ups. - **Web3 protocols.** DeFi, tokenization, exchanges, and the audits that keep them safe. ## Selected work - **Wallet, USA.** A multi-chain DeFi wallet taken from idea to launch in 10 weeks. - **Audit, Singapore.** Pre-mainnet audit on a [NEEDS-VALIDATION: founder] TVL DeFi protocol. [NEEDS-VALIDATION: founder] critical findings caught and fixed before launch, zero incidents since. - **Tokenization, USA.** A Reg D security-token build. The team put our audit report in their raise deck and closed [NEEDS-VALIDATION: founder]. ## Frequently asked questions **Are you a blockchain firm or a general agency?** A blockchain engineering firm. Blockchain and AI engineering is what we do, for fintech and Web3 teams. We do not run retail crypto or speculative token projects. **Why a firm instead of freelancers?** Freelancers build fast, ship broken, and disappear at handoff. We staff senior engineers, audit before launch, and stay through the first months in production. **Do you do AI work too?** Yes. AI agents and automation are a separate practice. Ask on the architecture review. **Who owns the code and IP?** You do, from day one. We sign an NDA before discovery on request. **How does an engagement start?** A 30-minute architecture review, then a fixed-fee discovery scope with a written plan and price. The build only begins once you sign that scope. **Where are you based?** [NEEDS-VALIDATION: founder] We work with clients across the US, UAE, Singapore, the UK, and Canada. ## Tell us what you are building. We will tell you how to build it right Book a 30-minute architecture review. We will review your project, point you to the right approach, and send a written scope and price range. No sales pitch. If we are not the right fit, we will tell you who is. NDA on request.

Privacy for them, compliance for you, less liability for everyone. 30 minutes with an identity architect, and we will map your verify-versus-store tradeoff. ## You need to verify users. You do not want the liability of storing their data | The old way | The DID way | |---|---| | You collect and store personal data | Users hold their own credentials | | You are a honeypot for breaches | Nothing for attackers to steal | | Re-verify users from scratch each time | Reusable, portable credentials | | Privacy and compliance fight each other | Selective disclosure satisfies both | Selective disclosure resolves the conflict: users prove the one thing you need, you verify it, and you never become the honeypot. ## What you can do with it - **Prove age without revealing birthdate.** Selective disclosure lets a user prove a claim and nothing more. - **Reusable KYC.** Verify once, reuse the credential across services. - **Sybil resistance.** One real human, one account, for airdrops and governance. - **Credential-gated access.** Show membership without exposing identity. - **Compliant onboarding.** Meet KYC and AML duties with less stored PII. ## What we build - **DID infrastructure.** W3C DIDs plus resolvers. - **Verifiable credentials.** Issue, hold, and verify on the W3C VC standard. - **Selective disclosure and ZK proofs.** Prove a claim, hide the rest. - **Wallet integration.** Credential wallets for your users. - **Reusable KYC flows.** Integrate KYC providers plus VC issuance. - **Proof of personhood.** Sybil resistance for access, airdrops, and voting. ## Who this is for - **Fintechs.** Compliant onboarding with less PII liability. - **Web3 products.** Sybil resistance and credential-gating. - **Enterprises.** Access across partners and suppliers. - **Marketplaces and platforms.** Stop re-verifying the same users. ## The path to launch 1. **Consultation and mapping (week 1).** Identity requirements plus a privacy and compliance map. 2. **Architecture (weeks 2 to 4).** DID and VC design plus standards choice. 3. **Build (weeks 5 to 12).** Issuance, verification, and wallet integration. 4. **Audit and compliance review (weeks 12 to 15).** Security plus regulatory check. 5. **Launch and support (week 15 and beyond).** Live system plus monitoring. ## Questions buyers ask - **What is decentralized identity in practical terms?** The user holds verifiable credentials in their own wallet and presents only the specific claim you need. You verify the claim cryptographically without keeping the underlying data. - **How does this help with KYC and AML compliance?** You still meet your verification duties, but you store far less personal data. A user can be verified once and reuse that credential. - **Do users need a crypto wallet?** They need a credential wallet, which we integrate into your product. It does not have to look or feel like a crypto wallet to the end user. - **Which standards do you build on?** W3C DID and Verifiable Credentials standards, so your credentials stay portable and interoperable instead of locking you in. - **How does selective disclosure or ZK fit in?** Selective disclosure lets a user reveal one claim, such as being over 18, without exposing their birthdate. Zero-knowledge proofs prove a statement is true while revealing none of the underlying data. - **Is it audited for compliance?** Yes. We audit for both security and regulatory fit, scheduled into the build before launch. ## Verify users, reduce liability, respect privacy, all at once A 30-minute call with an identity architect. No obligation. An identity architect responds within 1 business day. --- # Blockchain Node Infrastructure With Real Uptime SLAs | LBM Solutions URL: https://www.lbmsolution.com/blockchain-node-infrastructure # Blockchain node infrastructure that stays up when it matters Managed RPC, validators, and indexing with real uptime SLAs, so your app, your stakers, and your users never hit a dead endpoint. We review your current setup and flag the failure points. Free, no obligation, and you talk to an infra engineer. ## What "reliable" actually means here We publish only SLAs we can contractually stand behind. The exact uptime, latency, and response numbers are set against your stack in the reliability assessment. - **RPC uptime SLA.** A specific uptime figure written into the contract, not a best-effort promise. - **Validators monitored 24/7.** Slashing prevention, not just hosting. We watch the conditions that get stake cut. - **Fast indexed queries.** A response-time target on indexed reads, agreed in the SLA. - **Incident alerts fast.** An alert window measured in minutes, with on-call escalation behind it. ## Most teams do not notice their node infra until it fails - A down RPC takes your app down, and your users blame you. - A slashed validator costs you stake and trust at the same time. - A lagging indexer means stale data and broken UX. - Self-hosting to save money works until it costs you a launch. ## What we run - **Managed RPC endpoints.** Multi-chain, load-balanced, and redundant. - **Validator operations.** Staking, monitoring, and slashing prevention. - **Indexing and subgraphs.** The Graph and custom indexers. - **Archive nodes.** Full historical state for analytics and audits. - **Dedicated nodes.** Private, isolated infrastructure. - **Monitoring and alerting.** 24/7 coverage with real on-call escalation. ## Chains we support Ethereum, Polygon, Cosmos, Solana, Avalanche, Arbitrum, Optimism, Base, and BNB, among others. We confirm exact coverage for your stack in the assessment. ## How we onboard 1. **Reliability assessment (week 1).** Audit of your current setup plus a written risk report. 2. **Architecture and SLA (weeks 1 to 2).** Infrastructure plan plus a signed SLA. 3. **Migration and provisioning (weeks 2 to 4).** Nodes live and monitored. 4. **Handover and runbooks (week 4).** Docs plus escalation paths. 5. **Ongoing operations.** 24/7 monitoring plus monthly reports. ## Questions ops teams ask - **What uptime do you actually guarantee?** We commit to a specific uptime figure in the SLA and stand behind it contractually. We do not publish a number we cannot defend, so the exact figure is set in the reliability assessment. - **Do you prevent validator slashing?** Validators are monitored 24/7 with slashing prevention built in. We escalate before stake is at risk and treat your stake like ours. - **Which chains do you support?** Ethereum, Polygon, Cosmos, Solana, Avalanche, Arbitrum, Optimism, Base, and BNB, among others. We confirm exact coverage for your stack. - **Can you migrate our existing nodes with no downtime?** We stand up redundant infrastructure first, cut over behind a load balancer, and only decommission the old setup once the new one is proven. - **What is your incident response time?** Alerts fire within a defined window measured in minutes, with real on-call humans behind the escalation path. The exact targets are written into your SLA. ## Find your infrastructure's failure points before your users do A free review with an infra engineer and a written risk report. No obligation. We flag the failure points first. --- # Case Studies | LBM Solutions URL: https://www.lbmsolution.com/case-studies # Real projects, real outcomes We work under NDA, so most projects are described, not named. The work is real, and so are the numbers behind it. Here is a sample of what we have shipped and what it secured. ## What we have shipped - **Series A fintech, Singapore (Layer 1).** A sovereign appchain on Cosmos SDK, designed for real throughput and a defensible validator set before a public token launch. - **DeFi protocol, UAE (cross-chain bridge).** Validated message-passing with audited contracts on both chains, threat-modeled before a line of bridge code. - **Enterprise consortium, UK (permissioned network).** A Hyperledger Fabric network with role-based access and the documentation a procurement committee will sign off on. ## How to read these Each case study leads with one hard outcome, then walks through the challenge, what we did, and the result, with the tech stack and timeline named. Specific figures are confirmed with the client before they are published. ## Two ways from here See one that looks like your project?

Yours won't be Security-first cross-chain bridges with audited contracts, validated message-passing, and a threat model written before a line of code. Interoperability you can defend. We threat-model your bridge design on the first call. Talk to a security engineer, not a salesperson. ## Billions have been lost to bridge exploits. We build like we know that Bridges hold value in transit, which makes them the single most attacked surface in crypto. Every informed buyer knows the history, so we design for it from the first day. - **Threat model first.** We map every attack surface before we build. The risk picture comes before the quote. - **Audited message-passing.** Not just the contracts. The relay and the verification path are reviewed too. - **No single point of failure.** Multi-validator or proof-based verification, so one compromised key cannot drain the bridge. - **Audit before mainnet, always.** Independent audit is written into the scope. No exceptions, no grading our own homework. ## What we build - **Lock-and-mint bridges.** Classic asset bridging, hardened against the known exploit patterns. - **Burn-and-mint bridges.** Native cross-chain tokens with controlled supply across chains. - **Liquidity network bridges.** Fast swaps routed through pools, with slippage and depth controls. - **ZK and proof-based bridges.** Trust-minimized verification for the highest-value flows. - **Message-passing bridges.** Arbitrary cross-chain calls, not just token transfers. - **Bridge aggregator integration.** LayerZero, Wormhole, Axelar, and CCIP when a battle-tested layer fits. ## How we keep value safe across chains - **Verification layer.** How messages are proven: multi-sig, light client, or ZK, chosen to match your risk tolerance. - **Rate limits and circuit breakers.** Automatic pause on anomalies so an exploit cannot empty the bridge in one block. - **Monitoring.** On-chain watch with incident alerting, so a problem is seen fast, not after the funds move. - **Recovery plan.** What happens if something goes wrong, defined upfront and agreed in the scope. ## The path to mainnet 1. **Security architecture review (week 1).** Threat model plus a design recommendation. 2. **Bridge design (weeks 2 to 4).** A verified architecture spec. 3. **Build (weeks 5 to 12).** Testnet bridge with monitoring. 4. **Audit and pen test (weeks 12 to 16).** Independent audit report. 5. **Mainnet and monitoring (week 16 and beyond).** Live bridge plus ongoing on-chain watch. ## Questions buyers ask - **How do you prevent the exploits that hit other bridges?** We start with a written threat model that maps every attack surface, then design verification, rate limits, and circuit breakers around it. We close the known exploit paths before mainnet and confirm them in an independent audit. - **Do you build on LayerZero, Wormhole, or Axelar, or from scratch?** Both. When a battle-tested messaging layer fits your security and cost profile, we integrate it. When you need trust-minimized or custom verification, we build it. - **Is the audit included?** Yes. An independent audit is written into the scope, not sold as an add-on later. - **What happens if there is an incident after launch?** You get a recovery plan defined before mainnet, plus monitoring and circuit breakers that can pause the bridge automatically. We can stay on for incident response under a defined SLA. - **How do you handle cross-chain message verification?** We choose the verification model to match your risk tolerance: multi-sig, light client, or ZK proofs. The relay and verification path are reviewed alongside the contracts. ## Do not become the next bridge-hack headline A 30-minute call with a security engineer. Free threat model on the call.

Matching engines, custody, liquidity, and KYC/AML, engineered to fit your license. Scope your exchange build. Or book a compliance and architecture review. ## Let's be honest about who should build an exchange now A brand-new retail exchange in the US or EU rarely makes sense in 2026; licensing cost alone makes it a bad bet. The exchanges worth building now belong to three groups, and these are the teams we work with: - **Licensed VASPs** in MENA, LATAM, and Southeast Asia, building under a real regulatory framework. - **Existing exchanges** adding margin, derivatives, an OTC desk, or new markets. - **Wallets and super-apps** adding a swap or trading layer to an existing user base. If you are pre-license and pre-revenue, we will tell you so on the call. We would rather lose the project than build you something you cannot legally run. ## CEX, DEX, or P2P? | | Centralized (CEX) | Decentralized (DEX) | Peer-to-peer (P2P) | |---|---|---|---| | Core | Matching engine, custody | AMM or onchain orderbook | Escrow and dispute resolution | | Custody | You hold funds | Users hold funds | Users hold, escrow on trade | | Build time | 4 to 6 months | 2 to 3 months | 3 to 5 months | | Best for | Licensed operators, high volume | Web3-native, permissionless | Emerging markets, fiat on/off via users | ### Centralized exchange A performant matching engine (Go or Rust), hot and cold custody architecture with defined ratios, deep liquidity through market-maker and aggregator integration, and a full KYC/AML stack. We design the custody split and the operational runbook, not just the UI. ### Decentralized exchange AMM (Uniswap v3/v4 style) or onchain orderbook, liquidity-pool and LP-token design, and contracts audited before mainnet, because DEXs are the number-one hack target. Security here is the build, not a step in it. ### Peer-to-peer exchange Escrow contract design, a clear dispute-resolution flow, reputation and risk scoring, and a compliance model that adapts to each jurisdiction, since P2P rules vary sharply by country. ## What separates a real exchange from a template - **Matching engine.** Low-latency, high-throughput, built in Go or Rust, with order types your traders expect. - **Custody.** Hot and cold wallet architecture, MPC signing, withdrawal controls, and a documented key-ceremony process. - **Liquidity.** Market-maker integration and liquidity-aggregator connections so the book is not empty on day one. - **Compliance stack.** KYC and KYB (Sumsub, Jumio), transaction monitoring, sanctions screening, and Travel Rule support. - **Risk and ops.** Admin console, audit logs, rate limiting, and incident runbooks. ## Built for your license, not against it | Region | Framework we build to fit | |---|---| | UAE | VARA, ADGM | | Singapore | MAS (Payment Services Act, DPT) | | Bahrain | CBB crypto-asset rules | | El Salvador | Digital Assets framework | | Other | We adapt to your licensed jurisdiction | We are engineers, not your compliance officer. We build the controls your license requires and work alongside your legal and compliance team. ## Audited before launch, monitored after Exchanges and DEXs are the most-attacked systems in crypto. Every contract we ship is audited before mainnet using our five-layer process (see [smart contract audits](https://www.lbmsolution.com/smart-contract-audits)), and custody and withdrawal logic gets a dedicated security review. After launch, we monitor onchain and operational activity and respond to incidents fast. ## Recent work References available under NDA. We share exchange type, region, and real outcomes from launched white-label and operating exchanges under NDA on the architecture review. We do not publish numbers we cannot verify. ## Frequently asked questions **Do we need a license before we start?** For a CEX or fiat-handling exchange, you need a clear licensing path before launch. We can build during licensing, but we will not help you operate something you cannot legally run, and we will say so early. **Can you provide liquidity?** We integrate market makers and liquidity aggregators so your order book is not empty at launch. We connect the liquidity; we do not provide capital. **How is custody handled?** Hot and cold architecture with defined ratios, MPC signing, and withdrawal controls. We document the key ceremony and the operational runbook. **CEX, DEX, or P2P, which is right for us?** It depends on your license, your users, and your custody appetite. We work through it in the architecture review. **Is the exchange audited?** Yes. Contracts are audited before mainnet, and custody and withdrawal logic get a dedicated review. **Who owns the platform?** You do. NDA on request. ## Bring us your license and your market.

Multi-chain, MPC and account abstraction, custodial or non-custodial, shipped in 6 to 10 weeks. - Start your wallet build - Book a 30-min architecture review ## Trusted by fintech and Web3 teams across 18+ countries Chainml, Concordium, Tarality, Coinccino, OmoSwap, Seedx. ## The frustrating truth about building a crypto wallet When you are building a wallet, four things are true at once, and they pull against each other: - You can't risk security. One key leak and it is over. - You can't compromise on speed. A laggy wallet loses users in a day. - You can't depend on freelancers. They build fast, ship broken, and vanish. - You can't just hope it won't break. Hope is not an architecture. You are excited, and you are also a little overwhelmed. Too many chains. Too many security layers. Too many people telling you different things. And somewhere in the middle, the project stops moving. It does not have to be this complicated. ## First, who holds the keys? Every wallet starts with one choice, and most vendors skip the conversation. | Model | Who controls keys | Best for | Tradeoff | |---|---|---|---| | Non-custodial | The user | Web3-native apps, self-sovereignty | User loses keys, funds are gone; recovery design matters | | Custodial | You (the operator) | Fintech apps, exchanges, regulated flows | You hold liability and need custody-grade security | | MPC | Split across parties | Best of both, no single point of failure | More complex to build and integrate | | Account abstraction (ERC-4337) | Programmable (smart accounts) | Gasless UX, social recovery, session keys | Newer standard, needs careful implementation | We help you pick during the architecture review, based on your users, your regulatory position, and your risk tolerance. Most modern wallets we build land on MPC or account abstraction, often together. ## Security at every layer, not just the headline - **Key management.** MPC or smart-account architecture, hardware-backed where it fits, with a real recovery design (not just a seed phrase and a prayer). - **Contracts.** Wallet and account-abstraction contracts audited before launch (see our [smart contract audits](/smart-contract-audits)). - **Application.** Encrypted storage, secure enclaves on mobile, biometric and device binding. - **Infrastructure.** Hardened nodes, rate limiting, anomaly detection, and alerting. ## Wallet types we build - **Multi-chain wallets.** One wallet across Ethereum, Base, Solana, Polygon, and more, with unified balances. - **DeFi wallets.** Built-in swaps, staking, and dApp connection via WalletConnect. - **White-label wallets.** Your brand, your UX, our engine. Launch fast without rebuilding the core. - **Custodial and non-custodial wallets.** Either model, or a hybrid, built to your custody and compliance needs. - **Browser-extension wallets.** dApp-connecting extension wallets with a typed provider. - **Mobile and web wallets.** Native iOS and Android plus web, sharing one secure backend. ## From idea to launch in 6 to 10 weeks - **Discovery, week 1.** Users, chains, custody model, and compliance. Output: architecture and scope. - **Design and core build, weeks 2 to 6.** Key management, contracts, backend, and UI. - **Audit and harden, weeks 5 to 8.** Contract audit and security testing. - **Launch and support, weeks 8 to 10.** Production, monitoring, and a support window. ## Recent wallets we have shipped - **USA · DeFi wallet.** From idea to launch in 10 weeks. References available under NDA. - **UK · multi-chain mobile wallet.** 90% user satisfaction, zero security incidents. References available under NDA. - **Singapore · white-label wallet.** Launched fast, scaled to 25,000 users. References available under NDA. ## Why teams choose us - **Senior blockchain engineers.** Shipping on Ethereum, Solana, and Hyperledger since 2014, not learning on your budget. - **End-to-end product thinking.** We care about retention and UX, not just whether the contract compiles. - **Security at every layer.** Audited contracts, hardened infrastructure, real recovery design. - **Straight communication.** Regular updates, clear timelines, and honest feedback when a feature is a bad idea. We don't just build apps, we build confidence. ## Frequently asked questions **Custodial or non-custodial, which should we choose?** It depends on your users and regulatory position. Fintech and regulated flows often go custodial or MPC; Web3-native apps lean non-custodial or account abstraction. We decide together in the architecture review. **How long does a wallet take?** Most builds ship in 6 to 10 weeks. White-label is faster; custom key management and multi-chain support add time. **Is the wallet audited?** The contracts are, before launch, using our five-layer audit process. **Which chains do you support?** Ethereum, Base, Arbitrum, Optimism, Polygon, Solana, and others on request. **Who owns the code?** You do, from day one. NDA on request. **Can you do account abstraction and gasless transactions?** Yes. We build ERC-4337 smart accounts with session keys, social recovery, and sponsored gas.

Mechanism and oracle design done properly, audited before mainnet, built on Ethereum, Base, Arbitrum, and Solana. [Scope your protocol build](/contact) · [Book a mechanism-design review](/contact) ## What we build, and the risk each one carries A serious DeFi buyer knows the contracts are easy and the economics are where protocols die. Each primitive names what it does and the specific failure mode it carries. - **AMMs and DEXs.** Constant-product, concentrated-liquidity (Uniswap v3/v4 style), and stable-swap (Curve style) pools. *The risk: LP economics and price-manipulation via thin pools.* - **Lending and borrowing.** Isolated and pooled markets, variable rates, collateral factors. *The risk: oracle manipulation and bad-debt cascades during liquidation.* - **Perpetuals and derivatives.** Orderbook or vAMM perps, funding rates, margin. *The risk: funding and liquidation logic under volatile, low-liquidity conditions.* - **Yield and vaults.** ERC-4626 vaults, auto-compounding, strategy routing. *The risk: strategy composability and dependency on external protocols.* - **RWA-DeFi crossover.** Permissioned pools and tokenized collateral. *The risk: bridging compliant assets into permissionless mechanics.* ## The contracts are the easy part. The economics are where protocols die. Most exploits are not a missing require statement. They are economic: an oracle that can be pushed, a liquidation that does not clear fast enough, an incentive that pays attackers more than it pays users. We design these explicitly, before a line of the protocol is final. - **Oracle design.** Choosing and configuring price feeds (Chainlink, Pyth, TWAPs) so a flash-loaned swing cannot drain you. - **Liquidation mechanics.** Parameters and keeper incentives that clear bad debt fast, even in a market crash. - **Incentive and token design.** Emissions, fees, and rewards modeled so the protocol is solvent when the farming stops. - **Stress and scenario modeling.** We simulate the bad days, not just the happy path, before mainnet. ## Audited before mainnet, every time No DeFi protocol we build reaches mainnet unaudited. Security runs through the whole engagement. That means threat modeling at architecture, the full five-layer audit before launch, and onchain monitoring after. The audit covers Slither, Mythril, Echidna, Foundry, manual review, and Certora on critical paths. See the full audit process on [smart contract audits](/smart-contract-audits). ## How we build - **Contracts:** Solidity and Rust, Foundry-based workflow, OpenZeppelin libraries, upgradeable patterns where governance requires them. - **Frontend:** wagmi, viem, and RainbowKit for wallet connection; a typed SDK so integrators move fast. - **Oracles:** Chainlink, Pyth, and custom TWAPs per the risk profile. - **Infra:** subgraph indexing, keeper and bot infrastructure for liquidations and rebalancing, observability and alerting. - **Chains:** Ethereum, Base, Arbitrum, Optimism, Polygon, and Solana. ## Recent work - **[NEEDS-VALIDATION: founder] protocol type and region.** Built and shipped a protocol with $[NEEDS-VALIDATION: founder] TVL within [NEEDS-VALIDATION: founder] months of launch. Audited pre-mainnet, [NEEDS-VALIDATION: founder] incidents since. - **[NEEDS-VALIDATION: founder].** One-line problem, approach, and outcome with a number, pending founder validation. References available under NDA. Read the [case studies](/case-studies). ## From mechanism to mainnet | Phase | Timeline | What happens | |---|---|---| | Mechanism design | Weeks 1 to 2 | Economic model, oracle and liquidation design, parameter selection, and a written spec. | | Build | Weeks 3 to 8 | Contracts, SDK, indexing, and keeper infrastructure. | | Audit and stress test | Weeks 6 to 10 | Full audit and scenario modeling on testnet. | | Launch and monitor | Week 10+ | Guarded mainnet rollout with caps, then monitoring and incident response. | Timelines depend on primitive and complexity. Mechanism-design-only engagements are available as a smaller standalone scope. [Book a scoping call](/contact). ## Frequently asked questions **Can you design the tokenomics, or only build the contracts?** Both. Many teams come to us for the mechanism and economic design first, then continue into the build. You can book the mechanism-design review on its own. **Do you audit your own protocol builds?** Yes, with the same five-layer process we use for external audits, plus pre-mainnet stress testing. Some clients also commission a second independent audit, which we encourage and support. **Which oracle should we use?** It depends on the asset and the manipulation risk. We choose between Chainlink, Pyth, and TWAP designs during mechanism design, and configure for your specific market. **Can you fork Uniswap or Curve?** We can start from battle-tested designs where it fits, then engineer the parts that are specific to your protocol. We do not ship a blind fork with your logo on it. **Who owns the code?** You do. NDA on request. **How do you handle launch risk?** Guarded rollout: deposit caps, gradual limit increases, and active monitoring, so an early issue is contained, not catastrophic. ## Bring us the mechanism.

Model-agnostic, grounded in your sources with retrieval, and private by design. Shipped in weeks, not quarters. Book a generative AI discovery call. NDA on request. Your data stays yours. ## What we build This buyer self-identifies by what they are shipping. Each card is one concrete capability. - **Knowledge assistants.** Answers grounded in your documents, wikis, and data, with citations, so users can trust the output. - **Copilots in your product.** An assistant embedded in your app that helps users do the thing your product is for, faster. - **Document and data extraction.** Turn contracts, invoices, forms, and reports into structured, validated data. - **Content generation.** On-brand drafts, variations, and summaries at scale, with a human approving the output. - **Custom and fine-tuned models.** When a base model is not enough, we fine-tune or build for your domain, data, and latency. - **AI features in your product.** Search, classification, recommendations, and natural-language interfaces, added to what you already ship. ## First, which model, and grounded how? Every generative project turns on two choices, and most vendors pick for you to suit themselves. We pick for you, based on your data, privacy, latency, and budget. **Hosted frontier (OpenAI, Anthropic, Google).** Best for the fastest path and strongest reasoning. Data lives on the provider API, with no-training terms. Cost is per token. Tradeoff: less control and ongoing per-call cost. **Open-weight (Llama, Mistral).** Best for privacy, cost at scale, and control. Data lives in your cloud or VPC. Cost is infra-based and cheaper at high volume. Tradeoff: you run the infra. **Fine-tuned (custom).** Best for a narrow domain with strict latency or format needs. Data lives in your cloud or VPC. Cost is higher upfront and cheaper per call. Tradeoff: build effort and upkeep. The second choice is how to ground it. - **RAG.** Keeps answers current and cited without retraining. The default for most production systems. - **Fine-tuning.** Bakes in tone, format, or a narrow skill. We add it only when RAG alone cannot hit the bar. - **Most systems.** Use RAG, and add fine-tuning where needed. We recommend the combination during discovery, based on your data, privacy, latency, and budget. ## How we stop it from making things up Retrieval-augmented generation is how a model answers from your data instead of its training memory. We chunk and embed your sources, then store them in a vector database (Pinecone, Weaviate, Qdrant, or pgvector). For each question we retrieve the most relevant passages, rerank them, and give the model only what is relevant. The result is answers your users can verify, not confident fiction. The pipeline: your sources, to chunk and embed, to vector DB, to retrieve, to rerank, to answer with citations. The model is instructed to cite, and to say I do not know rather than guess. ## Where your data goes, in plain terms The question every serious buyer has and most agency pages skip. Plain, confident, no fearmongering. - **No silent training.** When we use a hosted model, we configure no-training and no-retention terms so your data is not used to train anyone's model. - **Private deployment.** When privacy demands it, we run open-weight models in your own cloud or VPC, so data never leaves your perimeter. - **PII handling.** Redaction and minimization before data reaches a model, with audit logging of what was sent. - **Access and tenancy.** Per-user and per-tenant access controls, so the assistant only ever sees what that user is allowed to see. - **Compliance.** We build to your framework, working with your security team. Applicable frameworks confirmed before publication: [NEEDS-VALIDATION: founder]. ## From discovery to shipped feature Most generative builds ship a useful prototype in 4 weeks and production in 6 to 12, depending on grounding complexity, model choice, and integration. - **Discovery, week 1.** We map your use case, data sources, model and grounding choice, and privacy needs. Output: a written spec and a recommended architecture. - **Prototype, weeks 2 to 4.** A working prototype on your real data, with evals so quality is measured, not guessed. - **Harden, weeks 4 to 8.** Grounding tuned, guardrails added, latency and cost optimized, integrated into your product. - **Ship and improve, ongoing.** Monitoring, evals on every change, and refinement as your data and needs grow. ## Recent work - **Grounded knowledge assistant.** A RAG assistant grounded in customer documents and policy, with citations and refusal on out-of-scope questions. Use case, region, and measured outcome: [NEEDS-VALIDATION: founder]. - **Document extraction pipeline.** Problem, approach, and measured outcome: [NEEDS-VALIDATION: founder]. References available under NDA. Anonymized is fine; we do not publish figures we cannot source. [NEEDS-VALIDATION: founder] ## Frequently asked questions **How do you stop the AI from hallucinating?** We ground it in your data with retrieval and force it to cite sources. We also instruct it to refuse when it does not know, and measure accuracy with evals before it ships. Grounding plus evals is how you get answers users can trust. **Which model should we use?** It depends on your privacy needs, cost at your volume, and how specialized the task is. We compare hosted, open-weight, and fine-tuned options in discovery and recommend, rather than defaulting to one vendor. **Do you train on our data?** No. We configure no-training and no-retention terms with hosted providers, and for strict cases we run models in your own cloud so data never leaves. **Can it run on our own infrastructure?** Yes. We deploy open-weight models in your cloud or VPC when privacy or cost calls for it. **RAG or fine-tuning?** Usually RAG first, because it keeps answers current and cited without retraining. We add fine-tuning only when RAG alone cannot meet the bar. **Who owns the model and code?** You do. NDA on request. ## Tell us what you want it to do.

Built by engineers who assume your contracts will be attacked, because they will. [Get my audit & build scope](/contact) We'll review your contracts or your spec and flag the risks before you commit. [Download our smart contract security checklist](/smart-contract-audits) ## Trust metrics - [NEEDS-VALIDATION: founder] TVL secured - [NEEDS-VALIDATION: founder] contracts deployed - Zero exploits in production [NEEDS-VALIDATION: founder] Trusted by protocol teams across the US, UK, and Singapore [NEEDS-VALIDATION: founder] ## 01 / The stakes: In Web3, your code is your security perimeter The moment your contract hits mainnet, it's public, immutable, and holding real money. Every line is a potential exploit, and there's no patch on Tuesday. One missed reentrancy and the whole protocol is gone. You can't: - ship contracts that haven't been independently audited - trust anonymous devs with your protocol's treasury - move slowly, but you can't move recklessly either - undo an exploit once it drains the pool So we: - audit independently before a single dollar is at risk - put a named, accountable team on your protocol - move fast on battle-tested patterns, not reckless ones - catch the exploit in review, before it ever ships The teams that survive don't hope their code is secure. They build to the audit standard, then prove it. ## 02 / How we build ### Audit-first, always Security is the starting point, not a final-week scramble. Every contract is built to pass independent review, and we audit other teams' contracts too. ### Adversarial engineering We build assuming an attacker is reading your code right now. Threat modeling, formal checks, and battle-tested patterns over clever ones. ### Mainnet-grade from day one Gas-optimized, upgrade-safe, and tested against the failure modes that have drained other protocols. ## 03 / What we build for protocol teams - [Smart contract audits](/smart-contract-audits): independent review before you risk real funds. - [DeFi protocol engineering](/defi-protocol-engineering): AMMs, lending, staking, and yield infrastructure. - [Crypto exchange development](/crypto-exchange-development): order books, custody, and matching engines. - [Crypto wallet development](/crypto-wallet-development): secure key management and signing. - [Tokenization & RWA](/tokenization-and-rwa): compliant token issuance and settlement. - [Token launch engineering](/learn/token-launch-guide): contracts, distribution, and vesting done right. ## 04 / Why protocol teams choose us ### Auditors and builders under one roof AUDIT + BUILD. We write secure contracts and we break insecure ones, so your build is reviewed by people who attack code for a living. ### Zero exploits in production [NEEDS-VALIDATION: founder] contracts deployed, [NEEDS-VALIDATION: founder] TVL secured, zero exploits. The record is the proof. ### No anonymous devs NAMED TEAM. A named, accountable team you can put in front of your investors and your community. ### Transparent scope and timeline FIXED SCOPE. Fixed scope, clear milestones, no surprise change orders before a token launch. ## 05 / Selected Web3 work References available under NDA.

Talk to an engineer, not a salesperson. No NDA needed for the first call. ## Most blockchain developers have never shipped a Layer 1 Building your own chain is the most demanding thing in this space. Consensus, validators, tokenomics, and economic security all have to be right on day one. - You cannot bolt sovereignty onto someone else's chain. - You cannot risk a consensus bug discovered after mainnet. - You cannot depend on a team that has only ever deployed a token. - You cannot explain to investors why launch slipped two quarters. There is a way to do this without betting the company on it. ## Three things we get right before your genesis block - **Consensus you can defend.** We pick and tune the consensus model to your security and throughput needs. Cosmos SDK, Substrate, and Tendermint experience, not theory. - **Validator-ready from genesis.** We hand you a chain with a working validator set and onboarding docs. Genesis ceremony and validator runbook included. - **Economic security designed in.** Tokenomics, staking, and slashing modeled before mainnet. We model the attack cost, not just the happy path. ## What we build - **Sovereign app-chains.** Cosmos SDK chains with custom modules. 10 to 20 weeks. - **Substrate and Polkadot parachains.** Runtime plus parachain integration. 12 to 24 weeks. - **Custom consensus layers.** Tendermint and BFT tuning for your throughput target. - **Validator and node infrastructure.** Genesis, validator set, and monitoring. - **Native tokenomics and staking.** Inflation, slashing, and governance baked in. - **Cross-chain connectivity.** IBC and bridge readiness from day one. ## The path to mainnet 1. **Architecture review (week 1).** Fixed scope plus a chain design doc. 2. **Consensus and tokenomics design (weeks 2 to 4).** Your economic security model. 3. **Core build (weeks 5 to 12).** Testnet running. 4. **Validator onboarding and audit (weeks 12 to 16).** Audited testnet and validator set. 5. **Mainnet launch and support (week 16 and beyond).** Live chain plus monitoring. ## Questions buyers ask - **How long to go from idea to mainnet?** Most chains reach testnet inside 12 weeks and mainnet in 16 to 28 weeks, depending on consensus and validator scope. - **Cosmos SDK or Substrate, how do you choose?** It depends on your throughput target, governance needs, and the ecosystem you want to connect to. We put the decision in writing. - **Who owns the code and the chain?** You do, from day one. Your repos, your genesis, your IP. NDA on request. - **Do you run validators after launch?** We hand you a working validator set and runbook, and we can stay on for monitoring under a defined SLA. - **How do you handle the audit?** Consensus and economic-security code is audited before mainnet. We schedule the audit into the build, not after it. ## Your chain could be on testnet in under 12 weeks A 30-minute call with a consensus engineer. No obligation. No NDA needed for the first call. --- # Layer 2 Development | ZK and Optimistic Rollups | LBM Solutions URL: https://www.lbmsolution.com/layer-2-development # Scale your dApp with the right rollup, without betting on the wrong one ZK or Optimistic, custom or off-the-shelf. We build the Layer 2 that matches your throughput, cost, and security needs. For teams that have outgrown a single chain. Talk to an L2 engineer, not a salesperson, and we will tell you which rollup fits, even if it is not the one you expected. ## Which Layer 2 is right for you? Most teams searching for an L2 already know they need one. The hard part is choosing the type. This is how to think about it. | If you need | Lean toward | |---|---| | Lowest fees, privacy, and fast finality | ZK Rollup | | EVM equivalence, simpler tooling, lower cost to build | Optimistic Rollup | | App-specific control and a custom gas token | Sidechain or Appchain | | Not sure yet | Book the call | We help you decide on the call, then build it. ## What we build - **ZK Rollups.** Validity proofs with the lowest finality risk. - **Optimistic Rollups.** EVM-equivalent and fast to ship. - **Custom sequencers.** Your own ordering and fee logic. - **L2 to L1 bridges.** Secure deposit and withdraw flows. - **Data availability setup.** Celestia, EigenDA, or blobs. - **Rollup-as-a-service deployment.** Built on OP Stack, Arbitrum Orbit, and zkSync. ## Why us - **We build both ZK and Optimistic.** So our advice is not biased by what we can sell. - **We benchmark your real workload.** Before we recommend an architecture, not after. - **Audit and bridge security are launch-blockers.** Treated as requirements, not afterthoughts. ## Recent work We share rollup type, region, and real outcomes such as fee reduction, migration time, and throughput at launch from deployed L2s on the strategy call. References are available under NDA. We do not publish numbers we cannot verify. ## Questions buyers ask - **ZK vs Optimistic, what actually decides it?** Your throughput target, finality needs, privacy requirements, and how much you want to spend to build. ZK gives faster finality and lower fees at higher build cost. Optimistic gives EVM equivalence and a simpler path to ship. We benchmark your real workload and put the recommendation in writing. - **Can you migrate our existing contracts to L2?** Yes. EVM-equivalent rollups let most contracts move with little change. We review your contracts and integrations first and tell you what, if anything, needs to be reworked before migration. - **How secure is the bridge?** We treat the bridge as a launch-blocker. Deposit and withdraw flows are designed for safety first and audited before mainnet, because bridges are where most L2 value is lost. - **Do we run our own sequencer or use a shared one?** It depends on the control and revenue you want versus the operational load you can carry. We work through the tradeoff in the strategy call and design either a custom sequencer or a shared setup to match. - **What is the timeline for a production rollup?** A framework-based deployment can reach a working testnet in a few weeks. A custom rollup build takes longer. You get a written timeline in the scaling audit before any build starts. ## Stop guessing which rollup to build. We will tell you in one call. A 30-minute call with an L2 engineer. An architecture recommendation, no pitch. An L2 engineer replies within 1 business day. --- # Optimistic Rollup Development | LBM Solutions URL: https://www.lbmsolution.com/optimistic-rollup-development # Launch your optimistic rollup without rewriting a single contract EVM-equivalent Layer 2 on the OP Stack and Arbitrum Orbit. Your existing Solidity ships as-is. For teams that need to scale now, not next year. Fixed price, fixed timeline, written into the contract. No scope creep. ## Why funded teams pick optimistic to ship fast Optimistic rollups push fees down dramatically against L1, so your users pay a fraction of mainnet gas. When time-to-market is the goal, it is the path that gets you live first. - **Your code just works.** EVM-equivalent by design. Your existing Solidity ships as-is. No rewrite, no reaudit of logic you already trust. - **Faster to build than ZK.** Lower complexity and lower cost mean a sooner mainnet date. Optimistic is the pragmatic path when time-to-market is the priority. - **Mature, battle-tested tooling.** OP Stack and Arbitrum Orbit are production frameworks with real ecosystems behind them. You build on proven rails, not a research project. ## What we build - **OP Stack rollups.** Optimism Superchain-compatible L2s. - **Arbitrum Orbit chains.** Custom Orbit L2 and L3 chains. - **Contract migration.** Your L1 contracts moved cleanly to L2. - **Custom gas tokens.** Let users pay fees in your token. - **Secure bridges.** Deposit and withdraw with fraud-proof safety. - **Sequencer and RPC setup.** Your own ordering and endpoints. ## The launch path Most clients are on mainnet in about 10 weeks. 1. **Scope and quote (week 1).** Fixed price locked in writing. 2. **Configure and deploy (weeks 2 to 5).** Testnet rollup live. 3. **Bridge and migrate (weeks 5 to 8).** Contracts on L2, bridge tested. 4. **Audit and harden (weeks 8 to 10).** Audited and monitored. 5. **Mainnet launch and support (week 10 and beyond).** Live rollup plus monitoring. ## Questions buyers ask - **Will my existing contracts work as-is?** Yes. OP Stack and Arbitrum Orbit are EVM-equivalent, so your compiled Solidity runs on the rollup without changes. We migrate the deployed contracts and verify behavior on testnet before mainnet. - **How fast can we be on mainnet?** Most framework rollup launches reach testnet inside five weeks and mainnet in about ten, depending on bridge and migration scope. The date is part of the fixed-fee contract. - **OP Stack or Arbitrum Orbit, which is right?** It depends on the ecosystem you want to plug into, whether you need an L2 or L3, and your gas-token and governance needs. We put the recommendation in writing before you commit. - **Is the fixed fee really fixed?** Yes. The price and timeline are written into the contract after the week-one scope. Any change to scope is approved by you before any change to cost. - **How do you secure the bridge?** Bridge and withdrawal code is audited before mainnet, not after. We schedule the audit into the build and monitor deposits and withdrawals after launch under an agreed SLA. ## Your rollup could be on mainnet in about 10 weeks A fixed-fee quote within 1 business day. Fixed price, fixed date. No credit card. --- # Oracle Integration for Smart Contracts | LBM Solutions URL: https://www.lbmsolution.com/oracle-integration # Connect your smart contracts to real-world data, safely Chainlink and multi-oracle integration done right: reliable price feeds, VRF randomness, and external data, hardened against the manipulation that drains protocols. We will scope your data needs and quote it, usually within 1 business day. Talk to an engineer, not a salesperson. ## What does your contract need from the real world? | Your use case | What we integrate | |---|---| | Your DeFi protocol needs prices | Price feeds (Chainlink Data Feeds), manipulation-resistant | | Your game or lottery needs fairness | Verifiable randomness (Chainlink VRF) | | Your contract reacts to events | Automation and keepers (time and condition triggers) | | You need off-chain API data on-chain | Any API to on-chain (custom external adapters) | | You need cross-chain data | CCIP and cross-chain messaging | | You back assets and need proof | Proof-of-reserves feeds for backed assets | ## A bad oracle integration is a drained protocol The data your contract trusts is your contract's attack surface. We treat the integration as a security problem first. - **Price manipulation.** Single-source feeds get gamed. We use aggregated, decentralized data. - **Stale data.** We add heartbeat and deviation checks so your contract never trusts an old price. - **Bad randomness.** Pseudo-random is exploitable. We use verifiable randomness. - **No fallback.** We design for oracle failure, not just the happy path. ## Oracles we work with Chainlink, Pyth, API3, Chronicle, and UMA. We are oracle-agnostic and pick the right provider for your latency, cost, and security needs, not just Chainlink by default. ## How the work runs 1. **Data scoping (days 1 to 3).** What data, what frequency, what risk, then a quote. 2. **Integration design (week 1).** Oracle choice plus safety mechanisms. 3. **Build and test (weeks 2 to 4).** Integrated and tested on testnet. 4. **Audit (weeks 4 to 5).** Integration reviewed for manipulation vectors. 5. **Mainnet and monitoring.** Live feeds, watched for staleness and deviation. ## Why us - **We harden against manipulation.** The number one oracle attack vector, designed out from the start. - **Oracle-agnostic.** The right provider for your case, not just Chainlink by default. - **Audited integrations.** The integration is reviewed, not just the contract. ## Questions buyers ask - **Which oracle should we use?** It depends on your latency, cost, and security needs. We are oracle-agnostic and pick the right provider, then put the decision in writing. - **How do you prevent price manipulation?** We use aggregated, decentralized data and add heartbeat and deviation checks, and the integration is reviewed for manipulation vectors before mainnet. - **Can you get any API on-chain?** Yes. We build custom external adapters that bring an API on-chain in a verifiable, fault-tolerant way. - **Is the integration audited?** Yes. We review the integration itself for manipulation and failure modes, not just the surrounding contract. - **What does it cost to run feeds ongoing?** It depends on the oracle, the number of feeds, and update frequency. We model the running cost during data scoping. ## Get the real-world data your contract needs, without the risk A scoped quote within 1 business day. No obligation.

Your gas, your throughput, your rules. Dedicated sidechains and appchains for products that have outgrown shared networks. Predictable fees, dedicated block space, and economics you control. We model your throughput and fee economics live on the call. Talk to an engineer, not a salesperson. ## Stop letting someone else's network decide your product's limits When your app outgrows a shared chain, its congestion, its fees, and its rules become your ceiling. An appchain gives you sovereignty over throughput and economics without the full weight of running a Layer 1. - Predictable, app-set fees instead of gas spikes you cannot control. - Dedicated throughput instead of block space you compete for. - Your own governance instead of network rules you cannot change. - Headroom you provisioned instead of congestion at your busiest moment. ## What we build - **Cosmos SDK appchains.** Custom modules, IBC-ready from day one. - **Polygon Supernets and CDK chains.** Polygon-secured appchains for EVM teams. - **Avalanche subnets.** A dedicated subnet with your custom VM. - **EVM sidechains.** Your own EVM chain plus a secure bridge. - **Custom gas token setup.** Users pay fees in your token, not someone else's. - **Bridge to L1 and L2.** Secure asset movement, audited before value flows. ## An appchain makes sense if any of these is true - Your fees on a shared chain are eating your unit economics. - You need guaranteed throughput at peak, for games and high-frequency apps. - You want a custom gas token or custom governance. - You are large enough that a shared chain's limits are now your limits. If you are pre-product-market-fit, we will tell you to stay on a shared chain. Honesty over upsell. ## The path to launch 1. **Design session (week 1).** Throughput and fee economics model. 2. **Architecture (weeks 2 to 4).** Chain spec plus bridge design. 3. **Build (weeks 5 to 14).** Testnet appchain running. 4. **Audit and bridge hardening (weeks 14 to 18).** Audited chain and bridge. 5. **Launch and ops (week 18 and beyond).** Live chain plus monitoring. ## Questions buyers ask - **Sidechain vs appchain vs L2, what is the difference for me?** A sidechain or appchain is a chain you control: your gas, throughput, and governance, secured by its own validators or a parent chain. An L2 inherits a base layer's security but shares its rules. We put the recommendation in writing. - **How is an appchain secured?** It depends on the framework. A Cosmos appchain runs its own validator set, a Polygon CDK or Supernet chain inherits Polygon security, and an Avalanche subnet runs a dedicated validator group. - **Can users pay gas in our own token?** Yes. A custom gas token is one of the main reasons teams move to an appchain. We set up the fee model and model the economics so it is sustainable. - **What does it cost to run ongoing?** Running costs depend on validator count, throughput, and monitoring scope. We give you a written estimate in the design session and can run the chain under a monthly SLA. - **Who maintains it after launch?** You own the chain and the code from day one. Run it yourself with the runbook we hand you, or we stay on for monitoring under a managed-ops agreement. ## Your product should not be limited by someone else's chain A 30-minute call with an engineer. We model your economics live. No obligation.

We audit Solidity, Rust, and Move contracts for fintech, DeFi, and tokenization teams. Get a fixed-fee audit quote. Fixed-fee quote in 48 hrs. See a sample audit report. ## Track record - [NEEDS-VALIDATION: founder] in TVL secured - [NEEDS-VALIDATION: founder] contracts audited since 2019 - Zero exploits on code we signed off - Audits delivered for Series A to C teams across the US, UAE, Singapore, and the UK. ## Most contract failures don't start in the code. They start in the audit. A clean audit report does not mean clean code. It means whoever reviewed it ran the usual tools and found nothing. That is not the same as security, and the difference is where the money gets lost. - A script ran, a PDF came back, and someone called it a review. - A junior did the work. The senior name on the cover never opened the repo. - Findings came back vague. No severity, no reproduction steps, no fix. - The audit shipped on time, and the bug shipped right alongside it. You are launching with real money on the line. Investors expect security. Users expect security. Your name is attached to all of it. A weak audit quietly puts the three at risk and you find out the hard way. An audit should be done right, not just done. Here is what that looks like. ## Five layers, applied to every contract regardless of size Tools catch the known patterns fast. Senior engineers catch the things tools were never built to see. We run both, in this order. 1. **Static analysis.** Slither and Mythril flag known vulnerability classes and dangerous patterns across the codebase. 2. **Fuzzing and symbolic execution.** Echidna and Foundry hammer your invariants with inputs your test suite never tried. 3. **Manual line-by-line review.** Two senior auditors read every line, focused on business-logic and economic flaws that no tool detects. 4. **Formal verification (on request).** Certora proofs on the critical paths, where a single wrong assumption drains the protocol. 5. **Remediation and re-audit.** We verify each fix and confirm it did not open a new hole. ## What you get, not just what we do Every engagement ends with a report your team can publish on the repo, hand to investors, and attach to the launch post. It contains: - Every finding rated Critical, High, Medium, Low, or Informational. - For each finding: reproduction steps, the impact if exploited, and a concrete recommended fix. - A fix-verification section confirming what was remediated and re-checked. - The exact tools, versions, and commit hashes reviewed, so the audit is reproducible. - The named auditors, their credentials, and our signed attestation. See a sample audit report. ## From a single contract to a full protocol Solidity, Rust, and Move. Each category lists a typical timeline so you can self-qualify before a call. - **DeFi protocols.** Lending, AMMs, perpetuals, options, yield aggregators. Multi-contract systems with composability risk. 3 to 8 weeks. - **Token contracts.** ERC-20, BEP-20, SPL, ERC-3643, ERC-721, with vesting, staking, and transfer restrictions. 1 to 2 weeks. - **Tokenization platforms.** Security tokens, real-world asset tokens, transfer-agent integrations. Compliance-aware. 4 to 8 weeks. - **Wallet contracts.** Custodial and non-custodial logic, MPC integrations, account abstraction (ERC-4337). 2 to 4 weeks. - **NFT and marketplace contracts.** Royalty enforcement, auctions, lazy minting. 2 to 4 weeks. - **Bridges and L2 contracts.** Cross-chain messaging and settlement. The highest-risk category we audit. 4 to 10 weeks. ## Scoping first. Everything else locks after. - **Week 1, scoping.** We review the codebase, define scope, map dependencies, and lock a fixed price. You get: a written scope and fixed quote you keep, whether or not you continue. - **Weeks 2 to 3, audit.** Two senior auditors run the full five-layer pass. You get: a preliminary findings report. - **Week 4, findings review.** We walk your team through each finding, severity, and fix. You get: a detailed findings document. - **Week 5, fix verification.** You implement, we re-audit the changes and confirm no regressions. You get: a fix-verification report. - **Week 6, final report.** Publishable report with our attestation. You get: the final PDF and signed attestation. ## A sample of recent work - **DeFi protocol · Singapore.** Pre-mainnet audit on [NEEDS-VALIDATION: founder] contracts in 4 weeks before token launch. Multi-tool plus manual review across [NEEDS-VALIDATION: founder] lines of Solidity, surfacing [NEEDS-VALIDATION: founder] critical and [NEEDS-VALIDATION: founder] high findings. All remediated, launched on time, no incidents in the [NEEDS-VALIDATION: founder] months since. - **Tokenization startup · USA.** A Reg D security-token contract needed an audit before filing. Six-week review including the regulatory framework and Securitize integration. The audit passed and the team put the report in their raise deck. References available under NDA. We link each engagement to a full case study once the client approves disclosure. ## Why teams choose us - **Senior auditors only.** Every audit is led by an engineer with 5+ years of Solidity and at least 20 prior audits. We do not put juniors on your code, and their names are on the report. - **Audit-first, not bolt-on.** We design for security from week 1. Our pre-mainnet checklist has [NEEDS-VALIDATION: founder] items, each with a documented fix path. - **Fixed fee, no scope creep.** Price locks in writing after scoping. If the codebase grows mid-engagement, we re-scope before we continue, not after. - **Post-launch guarantee.** If we miss a Critical or High finding and you hit it within 90 days of launch, we audit the fix at no charge and help with the disclosure. It is written into every contract. ## Frequently asked questions - **How long does an audit take?** A standard audit on 5 to 15 contracts runs 2 to 4 weeks: a week of scoping, two to three weeks of audit, plus a remediation cycle. Complex protocols needing formal verification run 4 to 8 weeks. We lock your timeline in writing during scoping. - **What tools do you use?** Slither and Mythril for static analysis, Echidna and Foundry for fuzzing, manual review by two senior auditors, and Certora for formal verification on request. Every report lists the exact tools and versions. - **Who owns the report?** You do. Publish it, share it with investors, or attach it to your launch.

Accept USDC, USDT, and PYUSD across Base, Arbitrum, Polygon, and Solana, with reconciliation and compliance built in, not bolted on. Get a payments integration plan. Book a 30-minute call. We map your payment and payout flows, show where stablecoin rails cut cost or settlement time, and send a written integration plan. See the integration docs: [Blockchain engineering](/blockchain-engineering). ## Why teams move B2B payments to stablecoins | | Card rails | Bank wire / ACH | Stablecoin rails | |---|---|---|---| | Cost per transaction | ~1.5% to 3.5% plus fixed | Flat fee, plus FX spread | Network fee, typically under 1% all-in | | Settlement time | 2 to 7 days | 1 to 5 days, slower cross-border | Minutes, 24/7, including weekends | | Cross-border | Expensive, FX layered | Slow, intermediary banks | Same flow domestic or international | | Chargebacks | Yes | Limited | None (final settlement) | | Programmability | Limited | None | Native (escrow, splits, conditional release) | For cross-border B2B volume, the saving is rarely the headline. The bigger win is settlement that clears in minutes and money that is programmable. ## Built for these flows - **Marketplaces and platforms.** Take stablecoin payments at checkout, split funds to sellers automatically, hold in escrow until delivery. - **Cross-border payouts.** Pay contractors, suppliers, and partners in 40+ countries without correspondent-bank delays. - **Treasury and settlement.** Move funds between entities and chains, hold yield-bearing stablecoins, reconcile to your ledger. - **On and off-ramps.** Let users convert fiat to stablecoins and back through a licensed partner, embedded in your product. ## What actually happens when a customer pays 1. **Customer pays.** They send USDC, USDT, or PYUSD from any wallet, or fiat through the embedded on-ramp. Your checkout shows a fixed price and a quote that does not move under them. 2. **We confirm and lock.** The transaction is verified on-chain, the amount is locked against your invoice, and price slippage is handled before confirmation. 3. **Funds route.** The payment splits to your accounts, sellers, or escrow per your rules. Conditional release and refunds are programmable. 4. **You reconcile.** Every payment maps to an invoice and posts to your ledger or ERP through the API and webhooks. No manual matching. ## What we build - **Checkout and invoicing.** Hosted checkout, embeddable widget, or a Stripe-style API. QR and link-based invoices for B2B. - **Payouts engine.** Single and batch payouts, scheduled disbursements, multi-chain, with cost-optimized routing. - **Treasury layer.** Multi-entity balances, internal transfers, sweep rules, and yield-bearing stablecoin support. - **On and off-ramp integration.** Fiat in and out through licensed partners, KYC handled at the ramp. - **Reconciliation and reporting.** Webhooks, ledger sync, exports for finance, and an admin dashboard. ## Assets and chains we support - **Stablecoins:** USDC, USDT, PYUSD, and others on request. - **Chains:** Base, Arbitrum, Optimism, Polygon, Solana, Ethereum mainnet. - **Routing:** We default to low-fee chains for payouts and let you set per-flow rules. ## Compliance is part of the build, not an afterthought - **KYC and KYB** through partners like Sumsub or Jumio, scaled to your risk tier. - **Travel Rule** support for transfers above threshold, via standard providers. - **Sanctions and wallet screening** on inbound and outbound flows. - **Regulatory framing.** We build to fit your registration, whether that is US MSB, EU MiCA, or operating under a licensed ramp and custody partner. We are engineers, not your lawyers, and we will tell you plainly where you need licensed counsel. Need the full audit and security picture before you ship? See our [smart contract audits](/smart-contract-audits) and [tokenization and RWA](/tokenization-and-rwa) work. ## Live in weeks, not quarters - **Discovery and design, week 1.** We map your flows, volumes, chains, and compliance needs and lock scope. - **Core integration, weeks 2 to 5.** Checkout or payouts, API, webhooks, and ledger sync in your environment. - **Compliance and testing, weeks 4 to 6.** KYC/KYB, screening, and end-to-end testing on testnet, then a controlled mainnet pilot. - **Launch and handover, week 6+.** Production, monitoring, and documented runbooks. Most B2B payment integrations ship in 6 to 10 weeks, depending on flows and compliance scope. [Book a scoping call](/contact) and we will map a timeline to your stack. ## Frequently asked questions **Do our customers need crypto wallets?** Not necessarily. With the embedded on-ramp, a customer can pay by card or bank and you still settle in stablecoins. For crypto-native counterparties, they pay directly from a wallet. **How do we handle accounting and reconciliation?** Every payment is tied to an invoice and posted through the API and webhooks to your ledger or ERP. We build the reconciliation layer, not just the rail. **Is this compliant in our market?** It depends on your jurisdiction and registration. We build to fit your framework (MSB, MiCA, licensed ramp and custody) and will be direct about where you need licensed counsel. **What about volatility?** Stablecoins hold a fiat peg, and prices are locked at checkout before confirmation, so the amount does not move under your customer. **Who owns the integration?** You do. Your code, your infrastructure, your keys. NDA on request. **Can you integrate with our existing stack?** Yes. We integrate with Shopify, WooCommerce, custom storefronts, and internal finance systems through the API. ## Tell us how money moves through your business Book a 30-minute call. We will map your payment and payout flows, show where stablecoin rails cut cost or settlement time, and send a written integration plan. No pressure, no jargon.

We will tell you honestly if a card or bank rail is the better fit for a given flow. --- # Blockchain Supply Chain Traceability | LBM Solutions URL: https://www.lbmsolution.com/supply-chain-traceability # Prove where every product came from, instantly, and beyond dispute End-to-end traceability that makes recalls faster, counterfeits visible, and audits painless. From raw material to shelf, every step is verifiable. Book a free 45-minute workshop and we will map your supply chain and show where traceability pays off. ## What traceability does for your business - **Recalls in hours, not weeks.** Trace an affected batch instantly and scope exactly which products are involved. - **Counterfeits exposed.** Every genuine item is verifiable, so fakes have nowhere to hide. - **Audits that take minutes.** An immutable, shareable record replaces the document hunt. - **Provable origin and ESG claims.** Back up ethically sourced with data, not a marketing line. - **Less dispute, more trust.** Partners see the same single record, so there is nothing to reconcile. ## When something goes wrong, can you trace it in minutes? - Paper trails and disconnected systems make recalls slow and costly. - Counterfeits slip in because origin cannot be proven. - Partners keep separate records that never quite match. - Sustainably sourced is a claim you cannot actually prove. The cost is not just the incident. It is the time, the disputes, and the trust you lose every time you cannot answer a simple question fast: where did this come from? ## One shared record everyone can trust 1. **Every step is recorded.** Source, process, ship, and receive are captured as the product moves. 2. **The record cannot be altered.** Once a step is written, it is locked. No quiet edits after the fact. 3. **Everyone sees the same truth.** Suppliers, logistics, and retailers read one shared record. No reconciliation. 4. **A scan reveals the full history.** A QR or NFC scan opens the complete, verified journey of any item. The shared record runs on enterprise blockchain. That is the how, not the headline. See the enterprise blockchain development page for the technical detail. ## What we build - **Provenance tracking.** Origin-to-shelf history for every item. - **Batch and lot traceability.** Instant recall scoping down to the lot. - **Anti-counterfeit verification.** QR and NFC authenticity checks. - **Partner network onboarding.** Suppliers, logistics, and retailers on one ledger. - **IoT and ERP integration.** Pull data from sensors and your existing systems. - **Consumer-facing verification.** Scan-to-verify for your end customers. ## Industries we serve Food and beverage, pharmaceuticals, luxury goods, manufacturing, agriculture, and automotive parts. ## How we get you there 1. **Use-case workshop (week 1).** Mapped supply chain plus an ROI estimate. 2. **Pilot design (weeks 2 to 4).** Scope, partner, and integration plan. 3. **Pilot build (weeks 5 to 12).** Live traceability on one product line. 4. **Validate and measure (weeks 12 to 16).** Measured outcomes against the ROI estimate. 5. **Scale (week 16 and beyond).** Roll out across product lines and partners once the pilot proves its numbers. ## Why us - **We start with your ROI, not the tech.** The pilot is designed to prove value fast. - **Integration-first.** Works with your ERP, IoT, and your partners' systems. - **Production-grade.** Built to scale beyond the pilot, not a demo. ## Questions buyers ask - **Do our suppliers need to use blockchain too?** No. Suppliers interact through simple web forms, a scan app, or a direct feed from their existing system. The shared ledger runs underneath. Onboarding is designed to take minimal effort on their side. - **How fast can we run a pilot?** Most pilots go live on one product line inside 8 to 12 weeks after the use-case workshop, depending on how many partners and systems we integrate. - **Does this integrate with our ERP and IoT?** Yes. Integration comes first. We pull data from your ERP, warehouse systems, and IoT sensors so the record builds from data you already capture, not double entry. - **How does it actually stop counterfeits?** Each genuine item carries a unique, verifiable identity tied to its recorded history. A QR or NFC scan confirms whether an item is authentic and where it came from, so a fake cannot present a valid record. - **What ROI do similar companies see?** It depends on your sector and where your current pain sits, such as recall cost, counterfeit losses, or audit time. We estimate the ROI for your specific chain during the workshop. We do not publish numbers we cannot verify. ## Turn we think it came from there into we can prove it A free 45-minute session. We map your chain and the ROI. No obligation.

Built on ERC-3643 and ERC-1400, integrated with transfer agents and KYC providers, structured to your jurisdiction. Book a tokenization structuring call. Download the RWA readiness checklist. ## What we tokenize - **Real estate.** Fractional ownership in single assets or funds, with rent distribution onchain. 8 to 16 weeks. - **Private credit and debt.** Tokenized loans and notes with coupon and repayment logic. 8 to 14 weeks. - **Funds and equities.** Tokenized fund units and private shares with transfer restrictions. 10 to 16 weeks. - **Invoices and receivables.** Short-duration, tradable receivables for working-capital finance. 6 to 12 weeks. - **Commodities and treasuries.** Tokenized treasuries and commodity-backed instruments. 10 to 16 weeks. - **Loyalty and utility (non-security).** Reward and access tokens on low-fee chains. 3 to 6 weeks. ## The hard part is not minting the token Minting a token is a day of work. The reasons RWA projects stall are never the token: - Who is legally allowed to hold and transfer it, and how the contract enforces that. - How identity, accreditation, and jurisdiction get checked before any transfer clears. - How the offchain legal structure (SPV, trust, fund) maps to the onchain token. - What happens at a coupon, a redemption, a corporate action, or a default. Get these right and the token is straightforward. Get them wrong and you have a security floating around with no controls, which is a problem you do not want to discover after issuance. ## Compliance built into the token, not stapled on after - **Permissioned token standards.** ERC-3643 (T-REX) and ERC-1400 enforce who can hold and transfer at the contract level, so a non-eligible wallet simply cannot receive the asset. - **Onchain identity.** ONCHAINID or equivalent ties each wallet to a verified, jurisdiction-aware identity claim, checked on every transfer. - **Transfer agent and registry.** Integration with a transfer agent and an authoritative ownership registry, so the cap table is always reconciled. - **KYC, KYB, and accreditation.** Sumsub, Jumio, or your existing provider gate onboarding and ongoing eligibility. - **Issuance and distribution platform.** Built on or integrated with established issuance platforms where it shortens your path, custom-built where it does not. We name only the partners we actually integrate with. This buyer will check. ## From issuance to redemption 1. **Structure.** Map the offchain legal entity to the onchain token, choose the standard, and define eligibility rules. 2. **Issue.** Mint to the registry, onboard investors through KYC, and enforce holding limits from day one. 3. **Distribute.** Primary sale to eligible investors, with the cap table reconciled onchain and offchain. 4. **Operate.** Coupons, dividends, rent, and corporate actions handled in code, with reporting for investors and regulators. 5. **Redeem or trade.** Compliant secondary transfers among eligible holders, redemptions, and end-of-life settlement. ## What we build on | Layer | What we use | |---|---| | Standards | ERC-3643 (T-REX), ERC-1400, ERC-20 for non-security wrappers, ERC-4626 for tokenized vaults | | Identity and compliance | ONCHAINID, Sumsub, Jumio | | Issuance partners | Established issuance platforms, named once verified | | Chains | Ethereum, Base, Polygon, Arbitrum, and permissioned chains where the framework requires it | We remove any partner we cannot back up. Named issuance partners are confirmed during structuring. ## The frameworks we build to fit | Jurisdiction | Framework we build to fit | |---|---| | United States | Reg D 506(c), Reg S, Reg A+ | | European Union | MiCA, plus prospectus rules for securities | | UAE | VARA and ADGM frameworks | | Singapore | MAS securities and DPT rules | We build the technology to fit the framework your counsel selects. We are engineers, not securities lawyers, and we work alongside yours. ## How we work - **Structuring workshop, week 1.** We align with you and your counsel on asset, entity, standard, and eligibility. Output: a technical and compliance spec. - **Build, weeks 2 to 8.** Contracts, identity, transfer-agent integration, and the issuance flow, audited before launch. - **Onboarding and issuance, weeks 8 to 12.** Investor KYC, primary distribution, and cap-table reconciliation. - **Operate and support.** Corporate actions, reporting, and secondary-transfer support after launch. Most RWA engagements run 8 to 16 weeks, scaling with asset complexity and compliance scope. Every contract is audited before issuance; see our [smart contract audits](/smart-contract-audits). ## Recent work **References available under NDA.** We share asset class, jurisdiction, and real outcomes from issued tokenized assets under NDA on the structuring call. We do not publish numbers we cannot verify. ## Frequently asked questions **Do you provide the legal structure?** No. You and your securities counsel choose the legal structure and offering exemption. We build the technology to fit it and integrate the transfer agent, identity, and KYC layers. **What token standard should we use?** For securities, usually ERC-3643 or ERC-1400, because eligibility and transfer restrictions are enforced at the contract level. We recommend based on your investors and jurisdiction during structuring. **How do secondary transfers work?** Only between eligible, verified holders, enforced by the token itself. We can integrate compliant secondary venues where your framework allows. **How are dividends, coupons, and rent handled?** In code, distributed to holders of record and reconciled to the registry, with investor and regulatory reporting. **Who owns the contracts and data?** You do. NDA on request. **Is the token audited before launch?** Always. Audit is part of the build, not an add-on. See our smart contract audit process. Building a DeFi layer or payment rails alongside the token? See [DeFi protocol engineering](/defi-protocol-engineering) and [stablecoin payment rails](/stablecoin-payment-rails). ## Bring us the asset. We will map the path to a compliant token Book a 30-minute structuring call. We will walk your asset, jurisdiction, and investors, outline the standard and compliance stack, and send a written plan. Bring your counsel; we work well with them. We build the technology and integrate compliance. Your legal structure stays with your counsel, where it belongs.

Reviewed by a ZK engineer. We will tell you honestly if a ZK rollup is overkill for your case. ## We work at the proving-system layer Not blockchain expertise. Proving-system expertise. - **Proving systems.** PLONK, Groth16, STARKs, and Halo2. We pick the system that fits your constraint count and verification cost, and we can defend the choice in a technical call. - **Rollup stacks.** Working familiarity with zkSync, Polygon zkEVM, Scroll, and Starknet, so you build on the stack that matches your EVM and tooling needs. - **Circuit engineering.** Custom circuit design and constraint optimization. The hard part of ZK is the circuit, and that is the work we do. ## Why ZK - **Validity, not assumption.** No seven-day challenge window. Finality is cryptographic, not optimistic. - **Privacy by construction.** Prove a statement is true without revealing the data behind it. - **Lowest long-run cost.** Proof compression beats paying to settle every transaction on L1. - **Audit-friendly security.** The security model is math you can review, not an assumption you have to trust. ## What we build - **zkEVM rollups.** EVM-compatible validity rollups for existing Solidity teams. - **App-specific ZK rollups.** Custom circuits tuned for one use case and its throughput target. - **ZK bridges.** Trust-minimized cross-chain transfers verified by proofs, not multisigs. - **Custom circuits.** Constraint-optimized circuits written for your specific logic. - **Prover infrastructure.** Proving and verification deployment, sized for your proof volume. - **ZK identity and privacy modules.** Selective disclosure and privacy-preserving verification. ## The path to mainnet 1. **Feasibility assessment (week 1).** Is ZK right for you, and which stack. Written recommendation. 2. **Circuit and architecture design (weeks 2 to 5).** Spec plus a constraint plan. 3. **Build and prove (weeks 6 to 16).** Working testnet with live proofs. 4. **Audit and optimization (weeks 16 to 20).** Audited circuits and performance tuning. 5. **Mainnet and prover ops (week 20 and beyond).** Live system plus monitoring. ## Questions buyers ask - **Do I actually need ZK, or is an optimistic rollup enough?** It depends on your finality, privacy, and cost requirements. If an optimistic rollup fits better, we will tell you in the feasibility assessment. - **Which proving system do you recommend and why?** It depends on your constraint count, verification cost, and the stack you want to settle on. We put the recommendation in writing. - **How long does a custom circuit take to build and audit?** Most app-specific circuits reach a proving testnet inside 16 weeks and complete audit and optimization by week 20, depending on circuit complexity. - **What does prover infrastructure cost to run?** Proving cost scales with circuit size and proof volume. We size and price the prover deployment as part of the architecture design. - **Who owns the circuit IP?** You do, from day one. Your circuits, your repos, your IP.
