CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom smart contracts that form the backbone of your Web3 application. Our development process is built on security-first principles, utilizing battle-tested patterns from OpenZeppelin and rigorous internal audits before deployment to EVM or Solana networks.
- Full-Stack Development: From
ERC-20tokens andERC-721NFTs to complex DeFi protocols and DAO governance systems. - Security & Audits: Mandatory peer review and automated analysis with
Slither/MythX. Optional formal verification for critical logic. - Gas Optimization: We write efficient code, often reducing gas costs by 20-40% versus unaudited implementations.
Deliver a secure, audited, and gas-optimized smart contract suite in 2-4 weeks for standard projects.
