overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3-native engineers.

We deliver audit-ready code for tokens, DeFi protocols, and NFT projects. Our engineers write in Solidity 0.8+ using OpenZeppelin libraries and implement industry-standard security patterns from day one.

Reduce your time-to-market with a 2-week MVP sprint for standard contracts like ERC-20, ERC-721, or a custom staking pool.

  • Security-First Development: Formal verification, comprehensive unit tests, and integration with Slither/MythX.
  • Gas Optimization: We benchmark and optimize for up to 40% lower transaction costs.
  • Full Lifecycle Support: From architecture and development to deployment, verification, and post-launch monitoring.
