About this Gig

Need a Solidity or Solana smart contract built, tested, or reviewed? I develop and audit Solidity contracts for Ethereum and EVM-compatible networks, and Rust/Anchor programs for Solana.


SERVICES

- DeFi components: DEX integrations, DAO governance, staking, vesting, presale and launchpad modules

- DeFi application frontend (wallet connection, contract interaction) and backend/API, quoted by scope

- Debugging, automated testing, gas/compute optimization

- Scoped smart contract security reviews with a written findings report

- Testnet deployment included in Standard and Premium; mainnet deployment available as an extra


Message me before ordering a complex protocol, full DeFi app or audit so we can agree on scope, testing and timeline. No security review can guarantee vulnerability-free code. Never share seed phrases or private keys.
