overview
CORE INFRASTRUCTURE
Custom Smart Contract Development
Secure, gas-optimized smart contracts built to your exact business logic.
- End-to-End Development: From specification and
Solidity/Rustcoding to deployment and verification onEVM,Solana, orCosmoschains. - Security & Audits: Built with
OpenZeppelinstandards and validated through third-party audits and formal verification. - Gas Optimization: Expert-level tuning to reduce user transaction costs by 15-40% and improve scalability.
- Upgradeability Patterns: Implementation of secure proxy patterns (
Transparent,UUPS) for future-proof, maintainable logic.
Deliver a secure, audited, and fully functional smart contract system in as little as 2-4 weeks.

Frequently Asked Questions
Get clear answers on timelines, security, and how our bridge development service works for your project.
For a standard cross-chain data availability bridge connecting two EVM chains, the typical timeline is 4-6 weeks from kickoff to mainnet deployment. This includes architecture design, smart contract development, integration of relayers or light clients, and a full security audit cycle. Complex multi-chain deployments or custom consensus mechanisms can extend this to 8-12 weeks. We provide a detailed project plan within the first week of engagement.
