We architect, develop, and audit custom Solidity/Rust contracts that form the core logic of your protocol. Our focus is on security-first development, leveraging battle-tested libraries like OpenZeppelin and implementing comprehensive test suites with >95% coverage before deployment.
Cross-Chain Asset Settlement Bridge
Smart Contract Development
Production-ready smart contracts built with enterprise-grade security and gas optimization.
- Full Lifecycle Support: From initial design and
Hardhat/Foundrydevelopment to mainnet deployment and upgrade management viaTransparentorUUPSproxies. - Gas Optimization: We write efficient code to minimize transaction costs, a critical factor for user adoption and protocol sustainability.
- Third-Party Audits: We prepare your code for and facilitate reviews with top security firms, ensuring no critical vulnerabilities before launch.
Core Bridge Capabilities
Our cross-chain bridge is engineered for financial institutions and high-volume protocols, delivering the security, speed, and reliability required for mission-critical asset transfers.
Multi-Sig MPC Security
Secure asset custody powered by a decentralized multi-party computation (MPC) network. Eliminates single points of failure and provides cryptographic proof for every transaction, ensuring funds are never at risk.
Sub-Second Finality
Near-instant settlement across supported chains (Ethereum, Polygon, Arbitrum, etc.). Our optimized relayer network and state validation achieve finality in under 1 second for most transfers.
Gasless User Experience
Abstract gas fees for end-users with meta-transactions and sponsored transactions. Users sign one approval; we handle the multi-chain gas complexity, drastically boosting adoption.
Programmable Settlement Logic
Go beyond simple transfers. Embed custom logic for conditional releases, time-locks, or KYC-gated flows directly into the bridge protocol using our modular smart contract framework.
Compliance-Ready Architecture
Built-in support for integration with AML/KYC providers and transaction monitoring tools. Maintain a verifiable audit trail of all cross-chain movements for regulatory requirements.
Business Outcomes for Your Payment Network
Our cross-chain bridge development delivers measurable infrastructure improvements, directly impacting your bottom line and user experience.
Reduced Settlement Time & Cost
Enable near-instant, cost-effective cross-chain transfers, slashing user wait times and transaction fees. Move assets between Ethereum, Arbitrum, and Polygon in under 2 minutes.
Enhanced Liquidity Access
Unlock fragmented liquidity across chains without manual bridging. Provide users with a single entry point to aggregated pools on EVM and non-EVM networks like Solana.
Enterprise-Grade Security & Audits
Deploy with confidence using battle-tested, formally verified bridge contracts. Our architecture includes multi-sig governance, rate limiting, and real-time monitoring.
Faster Time-to-Market
Leverage our modular bridge SDK and pre-audited components to launch your production-ready cross-chain payment rail in weeks, not months.
Build vs. Buy: Custom Bridge vs. Public Infrastructure
A detailed comparison of the total cost, risk, and time investment between developing a cross-chain bridge in-house versus partnering with Chainscore Labs for a custom, secure solution.

Our Security-First Delivery Process
We build cross-chain bridges with institutional-grade security, delivering production-ready infrastructure in weeks, not months. Our battle-tested process is designed to de-risk your integration and accelerate time-to-market.
Architecture & Threat Modeling
We begin with a comprehensive security-first design, mapping all attack vectors for your specific asset types and target chains. This includes formalizing trust assumptions, defining slashing conditions, and designing circuit breakers.
Smart Contract Development & Auditing
Development of core bridge contracts (lock/unlock, mint/burn) using Solidity 0.8+ and OpenZeppelin libraries. Code undergoes internal review followed by a mandatory audit from a top-tier firm like Quantstamp or Halborn before deployment.
Relayer & Validator Network Setup
Deployment of a decentralized, fault-tolerant relayer network with multi-sig governance. We configure validators for consensus on cross-chain messages, ensuring liveness and Byzantine fault tolerance.
Staging & Mainnet Deployment
Rigorous testing on testnets (Goerli, Sepolia) and a incentivized bug bounty program on Immunefi. We manage the full production deployment, including frontend integration, monitoring dashboards, and incident response playbooks.

Cross-Chain Bridge Development FAQs
Get clear, specific answers to the most common questions CTOs and founders ask when evaluating a cross-chain bridge development partner.
Our standard deployment follows a 4-phase agile process and typically takes 6-10 weeks from kickoff to mainnet launch. Phase 1 (2 weeks): Architecture & smart contract design. Phase 2 (3-4 weeks): Core development, including bridge contracts and relayer logic. Phase 3 (2 weeks): Internal audit, testing, and integration. Phase 4 (1-2 weeks): Deployment and final security review. Complex multi-asset or custom consensus bridges may extend this timeline, which we scope and quote for upfront.
