Blockchain Security Testing
Smart contract auditing, DeFi exploit detection, NFT security, bridge vulnerabilities, and on-chain attack patterns. Invoke this skill PROACTIVELY whenever: a target involves any smart contract, DeFi protocol, NFT marketplace, DAO governance, cross-chain bridge, yield aggregator, or token contract. Also invoke when you see Solidity/Vyper source code, etherscan links, contract addresses, or any blockchain-related functionality in a bug bounty target. If the target has ANY web3/blockchain component, this skill applies.
