A comprehensive guide to smart contract security for Solidity developers. Covers critical vulnerabilities like reentrancy, integer overflow, and access control issues, along with secure coding patterns, gas optimization techniques, and testing strategies for blockchain applications.

This skill provides production-ready Solidity smart contract templates for building DeFi applications including staking platforms, automated market makers (AMMs), governance systems, flash loans, and NFT standards. It includes comprehensive security best practices, vulnerability prevention patterns, and testing strategies using Hardhat and Foundry.

Implement DeFi protocols with production-ready templates for staking, AMMs, governance, and lending systems. Use when building decentralized finance applications or smart contract protocols.

A comprehensive token integration security analyzer based on Trail of Bits' checklist. Guides users through systematic analysis of ERC20/ERC721 tokens for conformity issues, weird token patterns (fee-on-transfer, rebasing, missing returns, etc.), owner privileges, and integration safety concerns. Provides structured report templates and checklists.
