Summary
The most critical subjects covered in our audit are correctness of the proxy upgrade and the overall functional correctness. Security regarding both subjects is high after Storage Collisions have been mitigated.
The documentation of the codebase is improvable.
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.
