CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
We architect, develop, and deploy custom Solidity/Rust smart contracts that are secure by design. Every contract undergoes formal verification and comprehensive audits before mainnet deployment, ensuring your protocol's logic is both powerful and protected.
- Custom Logic: Build DeFi primitives, NFT collections, DAO governance, or bespoke business logic.
- Security-First: Development follows OpenZeppelin standards and is tested against the latest attack vectors.
- Gas Optimization: We write efficient code to minimize transaction costs for your users.
- Full Lifecycle: From initial design and
Hardhat/Foundrytesting to deployment and upgrade management via Transparent Proxy patterns.
Deploy with confidence. Our contracts power protocols securing millions in TVL, with a 0 critical vulnerability track record post-audit.
