This skill provides a comprehensive toolkit for blockchain developers to validate smart contracts through advanced testing methodologies. It bridges the gap between JavaScript-based testing in Hardhat and Solidity-native testing in Foundry, offering patterns for unit tests, integration suites, and property-based fuzzing. Whether you are performing mainnet forking to simulate DeFi interactions or conducting gas optimization audits, this skill ensures your protocols are secure, efficient, and ready for deployment.
