How does this skill help prevent reentrancy attacks?

It provides specific code patterns like Checks-Effects-Interactions (CEI) and integration with OpenZeppelin's ReentrancyGuard to ensure state changes occur before external calls.

Can this skill help reduce transaction costs?

Yes, it includes advanced gas optimization techniques such as variable packing in storage slots and using calldata for read-only function arguments.

Does it support the latest versions of Solidity?

The skill covers modern Solidity (0.8+) which includes built-in overflow protection, as well as legacy patterns using SafeMath for older contracts.

Is this suitable for auditing DeFi protocols?

Absolutely. It identifies risks in complex interactions, including front-running mitigation through commit-reveal schemes and secure pull-payment patterns.

Security & Testing

Hardens Ethereum smart contracts against vulnerabilities using industry-standard security patterns and gas optimization techniques.

About

The Solidity Security skill equips Claude with expert-level knowledge to build, audit, and secure blockchain applications on Ethereum and EVM-compatible chains. It provides comprehensive patterns for preventing critical vulnerabilities such as reentrancy, integer overflows, and front-running, while implementing robust access control mechanisms. By leveraging the Checks-Effects-Interactions pattern and emergency stop protocols, this skill ensures smart contracts are production-ready, gas-efficient, and prepared for professional security audits.

Key Features

Reentrancy prevention using Checks-Effects-Interactions and ReentrancyGuard patterns
Secure access control implementation with Ownable and role-based permissions
Gas optimization strategies including storage packing and calldata utilization
Integer safety patterns for both legacy and modern Solidity versions
Emergency circuit breaker (Pausable) and Pull-over-Push payment implementations
1 GitHub stars

Use Cases

Auditing existing smart contracts for common security vulnerabilities and logic flaws
Developing secure DeFi protocols with built-in protection against economic attacks
Optimizing Solidity code for gas efficiency while maintaining rigorous safety standards
