Summary
The most critical subjects covered in our audit are asset solvency, cross-contract interaction and access control. Security regarding all aforementioned subjects is high.
In summary, we find that the codebase provides a high level of security. Discovered low-severity issues do not pose an immediate treat and can only be triggered by human error. They were addressed in Version 2 of the code; however redeployment was considered unwarranted. If bugs ever trigger, they can be mitigated by upgrading the system.
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.
