Summary
The most critical subjects covered in our audit are the usage of transient storage and functionalcorrectness. Functional correctness is improvable due to incorrect data being written, see Aave V3actions bad data written. Additionally, there could be reentrancy scenarios in bad setups, see ReentrancyInto the Contract. In case governance is untrusted, governance could add contracts such that this couldbe exploited. Further, the design is improvable due to Collisions on Operations.
The general subjects covered are documentation, trustworthiness and gas efficiency. Documentation isimprovable, see Unclear actions setup. Trustworthiness is satisfactory. However, it is improvable, see theparagraph above.
In summary, we find that the codebase provides a satisfactory but improvable level of security.
It is important to note that security audits are time-boxed and cannot uncover all vulnerabilities. Theycomplement but don't replace other vital measures to secure a project.
