Can this skill help reduce Ethereum gas costs?

Absolutely. It includes patterns for gas-efficient data types, storage packing, and using calldata instead of memory to minimize transaction fees.

Does it support the latest versions of Solidity?

Yes, it covers built-in security features for Solidity 0.8+ as well as legacy patterns and SafeMath implementations for older versions.

Can it help me prepare for a professional audit?

Yes, it provides a comprehensive security checklist and testing patterns to ensure your code is robust before submitting it to a third-party auditor.

What common vulnerabilities does this skill help identify?

The skill focuses on identifying and fixing high-risk vulnerabilities including reentrancy, integer overflows/underflows, front-running, and improper access control.

Does it use standard security libraries?

Yes, it strongly recommends and provides implementation patterns for OpenZeppelin's industry-standard contracts like ReentrancyGuard and Ownable.
