Here's a thinking process:
-
Analyze User Request:
- Topic: DeFi smart contract vulnerabilities
- Quantity: 3 common ones
- Requirement: Specific detection methods
- Format: List format
-
Identify Key Vulnerabilities in DeFi Smart Contracts:
I need to pick 3 of the most common, impactful, and well-documented vulnerabilities in DeFi. Good candidates:- Reentrancy attacks
- Integer overflow/underflow (though less common now with Solidity ^0.8.0, still relevant in older code or other languages)
- Access control issues (owner/admin key compromise, role-based access)
- Front-running / MEV related issues
- Oracle manipulation/price feed vulnerabilities
- Arithmetic errors (underflow/overflow in calculations)
- Logic bugs in liquidation, swapping, or minting/burning
