Automated and manual smart contract auditing with public security scores
Last updated: May 2026
CertiK is the highest-volume smart contract audit firm, having reviewed more protocols than any other security company — over 4,000 projects audited as of 2026. It combines automated formal verification tools with manual review, offering faster turnaround times than purely manual firms like OpenZeppelin or Trail of Bits. CertiK's Skynet platform provides continuous on-chain security monitoring for audited projects, tracking smart contract changes, governance actions, and abnormal token movements in real time. The SkyScore is CertiK's public security rating for each audited project — a composite score displayed on CertiK's website that has become a common due diligence reference for retail users evaluating new protocols. CertiK also runs one of the largest bug bounty platforms in Web3, Skynet Bug Bounty, where white-hat hackers can submit vulnerabilities for paid rewards. The trade-off relative to OpenZeppelin or Trail of Bits is that CertiK's volume means less time per engagement on manual analysis — some in the security community have noted that high-profile hacks have occurred on CertiK-audited protocols, which suggests automated tools have limits that manual expertise catches better.
Paid plans start at $299/month.
