Summary
The most critical subjects covered in our audit are functional correctness, access control, trustworthiness and reentrancies. Several issues regarding these topics have been remedied. Access control is handled correctly throughout. Potential reentrancy vulnerabilities have been addressed. The risk of an implementation contract SELFDESTRUCT was addressed. Several risk-free issues have been acknowledged and are by design, see Systemic bias towards accepting proposals, Proposal can be updated just before voting starts, Same proposal status for queued, executed or vetoed proposals.
The general subjects covered are upgradeability, gas efficiency and documentation. Security regarding these subjects is high. Some steps were taken to improve gas efficiency, which overall is decent. The level of documentation is satisfactory, however, some peculiarities highlighted in the Notes section could be more explicitly documented.
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.
