Sebastien Borge
COO & Co-founder

While traditional testing approaches merely attempts to detect bugs, the CertiK Software provides mathematical proofs that blockchain ecosystems are bug-free. That is one of the main reasons that convinced us to entrust these verifications to CertiK.

Justin Hyun
Head of Incubation

We were impressed with the suite of products offered by CertiK, which ranged from full-scope auditing, to security dashboards, and ongoing white hat support. CertiK saw the vision of what TON blockchain could be and wanted to develop that relationship early on, and to really think of different ways to add value across the board.

DeFi Chief of Staff

We don't want to preach security, we want to show everyone that we are secure. That’s why we did our two audits with CertiK, and why we enabled Skynet too. So everyone can do their own research, it's all out there. Go check it for yourself, and then believe us.

How Does It Work?

Our security audit platform evaluates smart contracts for vulnerabilities and certifies their behavior with respect to a custom function specification.

how it works

What’s in the audit report?

Our audit reports are custom, thorough, and transparent. The report will contain the details of any identified vulnerabilities and classify them by severity (Critical, Major, Medium, Low, and Informational), along with suggested remediations.

With every successful audit, we’ll provide you with a listing on the Web3 Security Leaderboard that is shared publicly with the entire crypto community. The Leaderboard contains the details of projects alongside their audit reports, as well as the community’s security sentiment of the project.

Our Experience

Our experience spans multiple smart contract protocol languages and platforms, and thousands of lines of code audited.
