A PROVEN PATH TO PRODUCTION
Our Development & Integration Process
From initial architecture to mainnet deployment, our structured process ensures your cross-chain settlement layer is secure, scalable, and delivered on time. We handle the technical complexity so you can focus on your product.
01
Architecture & Protocol Design
We design a custom settlement architecture based on your specific asset types (ERC-20, ERC-721, native tokens) and target chains (EVM, Cosmos, Solana). This includes selecting optimal bridging protocols (e.g., Axelar, LayerZero, Wormhole) and designing for atomicity and finality.

Smart Contract Development & Auditing
Our team builds the core settlement smart contracts in Solidity/Rust, implementing security-first patterns from OpenZeppelin. Every contract undergoes internal review and is prepared for a formal audit by a top-tier security firm like Trail of Bits or Quantstamp.

Relayer & Oracle Integration
We deploy and configure the off-chain infrastructure—secure relayers and decentralized oracles—required to monitor events and submit proofs across chains. This includes implementing robust retry logic, fee management, and high-availability setups.

CORE ENGINEERING
Smart Contract Development
Secure, gas-optimized smart contracts built for production from day one.
We architect and deploy custom smart contracts that are audit-ready and engineered for mainnet deployment. Our development process is built on security-first principles, utilizing OpenZeppelin libraries and formal verification patterns to mitigate risk.
- End-to-End Development: From specification and
Solidity 0.8+coding to testing, deployment, and verification. - Gas Optimization: Every contract is profiled and optimized for up to 40% lower transaction costs.
- Security Audits: Integrated review cycles and preparation for third-party audits from firms like CertiK or Quantstamp.
- Multi-Chain Ready: Deployments tailored for EVM chains (Ethereum, Polygon, Arbitrum) and Solana or Cosmos SDK.
We deliver production-grade contracts with a 99.9% uptime SLA and comprehensive documentation, enabling your team to iterate with confidence.
Technical & Commercial Details
Cross-Chain Middleware FAQ
Answers to the most common questions from CTOs and technical founders evaluating cross-chain settlement infrastructure.
Standard cross-chain bridge middleware deployment takes 2-4 weeks from kickoff to mainnet launch. This includes architecture finalization, smart contract development, integration testing, and security review. Complex multi-asset or custom consensus mechanisms can extend to 6-8 weeks. We provide a detailed project plan with weekly milestones.
