Summary

The most critical subjects covered in our audit are functional correctness, signature handling and correct interactions with the Gas Station Network (GSN).

Security regarding functional correctness and signature handling are high.

In summary, we find that the codebase provides a high level of security.

It is important to note that security audits are time-boxed and cannot uncover all vulnerabilities. They complement but don’t replace other vital measures to secure a project.
