Write Solidity, Vyper, and Move smart contracts. Large context models understand entire protocol codebases for consistent, secure contract implementation.
Reasoning models identify reentrancy, overflow, and access control vulnerabilities. Chain-of-thought analysis provides detailed audit reports with remediation steps.
Design tokenomics, liquidity mechanisms, and governance structures. JSON mode generates ABI definitions and contract interface specifications.
Build dApp frontends with ethers.js/wagmi, integrate wallet connectors, and create transaction builders. Function calling helps test contract interactions.
