How Does an L1 Chain 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:

What’s in a L1 Chain Audit Report?

Audit reports are comprehensive and fully transparent records that contain the details of all identified vulnerabilities. These are classified by severity from Critical to Informational. Each vulnerability is accompanied by suggested remediations from our team of smart contract security experts.

Vulnerabilities that are addressed before launch are marked as resolved. Issues that are acknowledged but unresolved are accompanied by a description of their possible effects and the project team’s justification.

Projects that undergo a completed audit earn a spot on the Web3 Security Leaderboard. This gives the entire Web3 community a powerful demonstration of a project’s commitment to security.

As part of our commitment to transparency and an open-source Web3 world, L1 chain audit reports are freely available to the public.
