The most critical subjects covered in our audit are functional correctness, asset solvency and signature handling. Security regarding Functional correctness and asset solvency is good. Signature handling is improvable, see Problems Related to Consent and ConsentVerification.

The general subjects covered are event handling and gas efficiency. Gas efficiency is improvable, see Gas Optimisation. Event handling can be improved as well, see Pausing and Unpausing Emit Misleading Events.

In summary, we find that the codebase provides an improvable level of security.

Many of the issues we identified during our assessment, which you have acknowledged without taking action, have the potential to cause human errors and other negative impacts. It is important to address these issues promptly to ensure the overall safety and reliability of your 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.
