Can this skill help optimize Ethereum gas fees?

Yes, it includes patterns for gas-efficient storage packing, utilizing calldata for function arguments, and selecting optimal variable types to reduce execution costs.

Does it support older versions of Solidity?

The skill covers both modern Solidity (0.8+) with built-in overflow checks and older versions using the SafeMath library pattern.

Is this a replacement for a professional smart contract audit?

No, this skill is a development tool designed to help you implement best practices and identify common issues early, but critical production code should always undergo a professional manual audit.

How does this skill help prevent reentrancy attacks?

It provides implementation guides for the Checks-Effects-Interactions pattern and demonstrates how to correctly use OpenZeppelin's ReentrancyGuard to prevent malicious recursive calls.
