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-specific (or strongly relevant to DeFi)
   • Must be 3 distinct vulnerabilities
   • Must be "specific" - not just generic names, but descriptions of what they are, how they work, impact, and maybe mitigation
   • Tailored for an audit report

3. Brainstorm DeFi Vulnerabilities:

   • Reentrancy (classic, but still relevant, especially with external calls)
   • Integer overflow/underflow (less common now with Solidity ^0.8.0, but still possible in older code or via library misusage)
   • Access control issues (owner-only functions, proxy
