DeFi Smart Contract Vulnerabilities Audit Guide

Here's a thinking process:

1. Understand User Request:

   • User wants 3 DeFi smart contract vulnerabilities for an audit report
   • Must be specific
   • Format: Describe 3 vulnerabilities

2. Identify Key DeFi Vulnerability Categories:

   • I need to pick three distinct, high-impact, and commonly exploited vulnerabilities that are well-defined and specific enough for an audit report.
   • Good candidates:
     • Reentrancy (but I should make it specific, e.g., "partial state update reentrancy" or "post-condition reentrancy")
     • Access control / privilege escalation
     • Math errors / overflow/underflow (though rare in modern Solidity, still relevant)
     • Front-running / MEV related
     • Oracle manipulation
     • Logic errors in incentive distributions
     • Flash loan abuse
     • Inadequate input validation
     • Timestamp dependency
