DeFi Smart Contract Vulnerabilities Audit Guide

Here's a thinking process:

  1. Analyze User Request:

    • Topic: DeFi smart contract vulnerabilities
    • Quantity: 3 common ones
    • Requirement: List them and explain how to detect each, with specificity
    • Format: List format, specific detection methods
  2. Identify 3 Common DeFi Vulnerabilities:
    I need to pick the most prevalent, impactful, and well-documented ones in DeFi smart contracts. Good candidates:

    • Reentrancy attacks (e.g., The DAO)
    • Integer overflow/underflow (though less common now with Solidity ^0.8.0, still relevant in older code or other languages)
    • Access control issues (owner-only functions, proxy patterns)
    • Front-running / MEV exploitation
    • Oracle manipulation/price feed issues
    • Flash loan attacks (often via reentrancy or invalid math)
