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
   • Requirement: Be specific

2. Identify Key Requirements:

   • Must be DeFi-specific (or heavily relevant to DeFi)
   • Must be 3 distinct vulnerabilities
   • Must be specific (not generic "hack" descriptions, but technical details suitable for an audit report)
   • Should be practical, actionable, and reflect common high-severity findings

3. Brainstorm DeFi Vulnerabilities:

   • Reentrancy (but need to make it specific to DeFi, e.g., external call order, missing checks-effects-interactions)
   • Flash loan attacks / oracle manipulation
   • Integer overflow/underflow (though less common now with Solidity ^0.8.0)
   • Access control issues
