Is it suitable for DeFi development?

Yes, it covers critical DeFi security requirements including front-running mitigation through commit-reveal schemes and secure pull-payment systems.

Does it support the latest Solidity versions?

Yes, it includes patterns for Solidity 0.8+ which features built-in overflow checks, while also providing SafeMath patterns for legacy projects.

How does this skill help prevent reentrancy?

It enforces the Checks-Effects-Interactions (CEI) pattern and provides templates for using OpenZeppelin's ReentrancyGuard to prevent unauthorized recursive calls.

Can it help with gas optimization?

Absolutely. It provides specific techniques for packing storage variables, utilizing calldata over memory, and leveraging events to minimize on-chain costs.
