Here's a thinking process:
-
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
-
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)
