How Does a Smart Contract Audit Work?

Every audit involves comprehensive manual review by our team of experienced security experts. Formal verification certifies L1 chain code behavior with respect to custom function specifications, helping developers get a handle on the entire scope of their platform. The process of auditing an L1 is the same as for auditing a smart contract. The five-step process is as follows:

Report an incident if you are under cyber attack and need help!

24/7 Incident Response
