Can this skill help optimize Ethereum gas fees?

Yes, it includes techniques for storage packing, using calldata instead of memory, and optimizing variable types to significantly reduce transaction costs.

Can this skill generate security unit tests?

Yes, it provides templates for Hardhat and Ethers.js tests specifically designed to verify security constraints like access control and overflow prevention.

Does it support both legacy and modern Solidity versions?

The skill covers modern Solidity (0.8+) with built-in overflow checks and provides SafeMath patterns for older versions to ensure comprehensive protection.

How does this skill help prevent reentrancy attacks?

It provides specific implementation patterns for the Checks-Effects-Interactions (CEI) method and demonstrates how to correctly use OpenZeppelin's ReentrancyGuard modifier.

安全与测试

Implements industry-standard smart contract security patterns and prevents common vulnerabilities in Ethereum-based applications.

关于

The Solidity Security skill empowers Claude to act as a security-first blockchain developer, specializing in the identification and mitigation of critical smart contract vulnerabilities. It provides detailed guidance on implementing robust patterns like Checks-Effects-Interactions, Pull over Push payments, and gas-efficient storage packing. By integrating best practices from OpenZeppelin and modern Solidity standards, this skill helps developers build resilient DeFi protocols, secure NFTs, and production-grade smart contracts while reducing the risk of reentrancy, front-running, and access control breaches.
