How does this skill help prevent reentrancy attacks?

The skill guides the implementation of the Checks-Effects-Interactions pattern and recommends using OpenZeppelin's ReentrancyGuard for contracts making external calls.

Can this skill help reduce Ethereum gas fees?

Yes, it provides specific techniques for gas optimization, such as packing storage variables into 256-bit slots and utilizing calldata for function arguments.

Does the skill support older versions of Solidity?

It provides best practices for both modern Solidity (0.8+) with built-in overflow checks and older versions requiring SafeMath libraries.

Is it suitable for DeFi protocol development?

Yes, it includes advanced patterns for front-running mitigation, commitment schemes, and emergency stop (circuit breaker) mechanisms essential for DeFi.

What security frameworks does it integrate with?

The skill is designed to work with industry standards like OpenZeppelin for access control and Hardhat/Chai for automated security testing.

보안 및 테스팅

Implements industry-standard security patterns and vulnerability prevention for Solidity smart contract development.

소개

This skill equips Claude with specialized knowledge to write, audit, and optimize Ethereum smart contracts with a focus on high-stakes security. It provides deep technical guidance on preventing critical vulnerabilities like reentrancy and integer overflows while promoting the use of secure architectural patterns such as Checks-Effects-Interactions. Whether building complex DeFi protocols or simple ERC-20 tokens, this skill helps developers implement robust access controls, gas-efficient storage, and emergency circuit breakers to ensure code is audit-ready and resilient against common blockchain attack vectors.
