What are the main types of smart contract audits?

The main types include manual audits, automated analysis using tools, static analysis, and formal verification. Each has a specific role in identifying different classes of vulnerabilities.

Which audit type is best for DeFi protocols?

DeFi protocols often use a mix of audit types — manual audits for logic, static tools for known bugs, and formal methods for verifying critical financial logic.

Is manual auditing still necessary with tools?

Yes. While automated tools catch many known issues, manual code reviews are essential for identifying complex logic flaws and security edge cases.

What is formal verification in smart contract auditing?

Formal verification uses mathematical proofs to ensure that a smart contract behaves as expected under all conditions, ideal for high-stakes crypto projects.

Are automated audit tools like Slither enough?

Automated tools provide great baseline coverage but should always be combined with manual review for full security.
