A collection of 48 Solidity smart contract vulnerability labs with Foundry-based proof-of-concept tests, originally built as internal Web3 security training at XREX. Each lab demonstrates a common DeFi vulnerability (reentrancy, overflow, selfdestruct, unsafe delegatecall, etc.) with an exploitable test case.

Use cases

• learn common smart contract vulnerabilities
• practice exploiting solidity bugs with foundry
• web3 security training exercises
• study reentrancy and delegatecall attack examples
• prepare for smart contract security audits
• reproduce solidity vulnerability proof of concepts

When to choose

• you want hands-on labs for learning Solidity security
• you already use Foundry and want realistic vulnerability examples
• you're training for web3 security or audit work

When to avoid

• you need production-ready secure contract templates
• you want a vulnerability scanner rather than educational material
• you need a formally licensed or audited codebase (no license provided)
