What Is a Smart Contract Audit?
A smart contract audit is like a deep check-up for your code. Experts review every line to spot risks like reentrancy attacks, flash loan exploits, or logic errors. They test edge cases and simulate hacks.
Audits include:
- Manual code review by pros.
- Automated tools for quick scans.
- Fix recommendations and re-tests.
- Post-audit monitoring in some cases.
After fixes, projects get a clean bill of health. This builds trust with users and investors.

Web3 is exploding with new chains and complex apps. Cross-chain bridges and AI-integrated dApps bring fresh risks. In 2025 alone, over $3 billion was lost to exploits. In 2026, expect even more as TVL hits new highs.
