CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built for production, from MVP to enterprise scale.
We architect and deploy custom smart contracts on EVM and Solana that power your core business logic. Our process delivers production-ready code in 2-4 weeks, backed by formal verification and multi-audit security practices.
- Security-First Development: Built with
Solidity 0.8+andOpenZeppelinstandards, hardened against reentrancy, overflow, and front-running attacks. - Full Lifecycle Support: From initial design and
Truffle/Hardhattesting to mainnet deployment and upgrade management viaProxypatterns. - Audit-Ready Code: Every contract includes comprehensive documentation,
NatSpeccomments, and test coverage exceeding 95%.
We don't just write code; we deliver verifiable, gas-optimized systems that handle real value. Our contracts have secured over $500M+ in TVL for DeFi and NFT projects.
