Defensive Smart Contract Engineering

Defensive Smart Contract Engineering is the practice of writing code with the explicit assumption that it will be targeted by malicious actors. This involves rigorous testing, formal verification, minimizing the attack surface, and implementing multiple layers of security.

It includes practices like checking all inputs, avoiding reentrancy vulnerabilities, and ensuring that no single function can compromise the entire system. It is a mindset that prioritizes security above all else, especially in financial applications.

This approach is necessary given the immutable and high-stakes nature of blockchain-based finance. It is the gold standard for developing reliable decentralized applications.
