DeFi Smart Contract Vulnerabilities Audit Guide

Here's a thinking process:

  1. Analyze User Request:

    • Topic: DeFi smart contract vulnerabilities
    • Format: 3 specific vulnerabilities for an audit report
    • Goal: Describe them specifically for an audit context
  2. Identify Key Requirements:

    • Must be DeFi-related
    • Must be smart contract vulnerabilities
    • Must be 3 distinct items
    • Must be "specific" (not generic, actionable, technical)
    • Intended for an audit report
  3. Brainstorm DeFi Vulnerabilities:

    • Reentrancy (classic, but need to make it specific/modern)
    • Integer overflow/underflow (less common now with Solidity 0.8+, but still relevant in legacy code or via library bugs)
    • Access control issues (owner key compromise, proxy admin takeovers)
    • Oracle manipulation/price feed attacks
    • Flash
