The most critical subjects covered in our audit are asset solvency, functional correctness, and access control.

Furthermore, the implementation of EIP-4626 can be improved: EIP-4626 Non-Compliance. All other mentioned subjects show a high level of security.

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.
