CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by expert auditors and deployed to your mainnet.
We architect and deploy custom smart contracts for DeFi, NFTs, and enterprise applications. Our team of expert auditors writes in Solidity, Rust, and Vyper, following OpenZeppelin standards and formal verification patterns to eliminate critical vulnerabilities before deployment.
- Full Lifecycle Support: From initial spec and
Hardhat/Foundrydevelopment to mainnet deployment and post-launch monitoring. - Security-First: Every contract undergoes manual review, automated analysis with
Slither/MythX, and test coverage exceeding 95%. - Gas Optimization: We specialize in high-frequency DeFi logic and NFT minting optimizations, reducing user costs by 30-60%.
Deploy with confidence. We’ve secured over $500M+ in TVL across client protocols with zero critical vulnerabilities post-audit.
