Can it assist with gas optimization in smart contracts?

Yes, it provides specific patterns for packing storage variables, using calldata instead of memory, and utilizing events to reduce on-chain storage costs.

Is this skill useful for professional security audits?

While not a replacement for a human audit, it provides a comprehensive 15-point checklist and pattern recognition to identify common vulnerabilities before a contract is sent for official review.

How does this skill help prevent reentrancy attacks?

It guides developers in implementing the Checks-Effects-Interactions pattern and integrating OpenZeppelin's ReentrancyGuard to prevent attackers from recursively calling functions before state updates.

Does it support modern Solidity versions?

Absolutely. It includes best practices for Solidity 0.8+ (which has built-in overflow checks) as well as legacy support using SafeMath for older versions.

安全与测试

Secures Ethereum smart contracts by implementing industry-standard patterns and identifying critical vulnerabilities like reentrancy and access control flaws.

关于

The Solidity Security skill empowers developers to build robust blockchain applications by applying deep-seated security principles directly within the Claude Code environment. It provides actionable guidance on preventing common Ethereum vulnerabilities such as reentrancy attacks, integer overflows, and front-running through proven patterns like Checks-Effects-Interactions and Pull-over-Push. Whether you are auditing existing codebases or architecting new DeFi protocols, this skill ensures your smart contracts are gas-optimized, battle-tested, and ready for professional audits.
