overview
CORE SERVICE

Smart Contract Development

Secure, audited smart contracts that power your Web3 product's core logic.

We architect and deploy production-grade smart contracts for ERC-20, ERC-721, and custom protocols. Our development process ensures gas-optimized code, upgradeable architecture, and comprehensive test coverage (>95%) before your first audit.

  • Security-First Development: Built on Solidity 0.8+ using OpenZeppelin libraries and established security patterns.
  • Full Lifecycle Support: From initial design and Hardhat/Foundry testing to mainnet deployment and verification.
  • Measurable Outcomes: Reduce critical vulnerabilities by 99%* and achieve audit readiness in 2-3 weeks.

We deliver the secure, battle-tested foundation your DeFi, NFT, or DAO application requires to launch with confidence.
