This handles the full Web3 development stack, from writing Solidity smart contracts to integrating wallet connections and building DeFi protocols. You get explicit support for common token standards (ERC-20, ERC-721, ERC-1155), security auditing for vulnerabilities like reentrancy attacks, and Layer 2 integrations with Arbitrum, Optimism, and Base. The skill includes guidance on gas optimization, Account Abstraction with ERC-4337, and blockchain indexing through The Graph. It's comprehensive enough for both contract development and frontend dApp work, though with 163 installs and mixed security audit results (failed Gen Agent Trust Hub, passed Socket), you'll want to review its suggestions carefully before deploying anything to mainnet.
