As the Sui ecosystem continues to grow, CertiK continues to provide the expertise and tools necessary to help secure their systems from the ground up.
Method
How do Sui project audits work?
The audit process kicks off with a detailed analysis of a project's entire codebase.
On occasion and when deemed necessary, CertiK reserves the right to conduct a Team Verification (KYC) check on a project it suspects to be high risk.
