DeFi Security: Best Practices for Smart Contract Development
Posted by Sarah Mitchell on April 8, 2025
The DeFi ecosystem has seen explosive growth, but with it comes increased scrutiny on security practices. Smart contract vulnerabilities have led to billions in losses, making security a top priority for any serious DeFi project.
Common Vulnerabilities
Understanding common attack vectors is the first step in building secure contracts:
- Reentrancy Attacks: When external calls can manipulate contract state before completion.
- Flash Loan Attacks: Exploiting price oracle manipulation through large, uncollateralized loans.
- Front-running: MEV bots exploiting transaction ordering for profit.
