Smart contract audit process


After contacting us, our engineers will review your source code.


We'll send you a quote customized for your project. We offer affordable pricing because we know that security is important and you shouldn't ever have to settle for a lower level of security.


Our audits combines rigorous formal verification, static analysis, and manual review. Unlike traditional security audits, formal verification mathematically proves that the code will always work as intended, computing all possible scenarios.


Once the audit is complete, the team will prepare an initial report that identifies vulnerabilities from critical all the way down to informational. Certik offers free unlimited re-audits. We'll also include Certik's Formal Verification labels in-line to show the work and explain the mathematical proofs conducted.


After final review of the source code, Certik will deliver the audit report and a cryptographically secured badge. This badge contains a QR code for anybody to scan as a proof of authenticity of the successful audit.


"CertiK's Formal Verification bypasses the limits of manual detection, offering one of the most thorough audits in the industry."
