QuillAudits is a top-tier blockchain security firm with 7+ years of experience and a proven track record securing 1,400+ Web3 projects.

At QuillAudits, we go beyond code analysis. We partner with you to protect your protocol, reputation, and users. We’ve audited projects across DeFi, GameFi, NFTs, and L1/L2 chains, securing $3B+ in TVL with zero critical post-audit exploits.

Trusted by industry leaders like Optimism, Starkware, BNB, Unichain, Soneium, Alliance, Plume, Taiko, Metis, and many more.

Every audit is conducted by a team of senior and mid-level auditors, supported by independent reviewers (Vigilant Squad) to ensure nothing is missed. Our approach blends manual review, automated tools, fuzzing, and logic testing.

Use Cases
