Quadrata Lending
Summary
**After initial audit:** Quantstamp has performed an audit of the Quadrata lending contracts and has found 11 security issues, 1 specification issue, 4 code documentation issues, and 13 deviations from best practices. Additionally, we note that test coverage is relatively low and should be improved. We recommend addressing all of these issues before deploying the code in production. <br><br> While no immediate issues were found in the bookkeeping/structuring and changing/accessing of passport attributes `_attributes` and `_attributesByDID` in `QuadPassportStore.sol`, their design seems to be overly complicated and potentially error-prone. We suggest considering a simpler design of said structures and functions. <br><br> **After reaudit:** Quantstamp has performed a reaudit of the Quadrata lending smart contracts and has updated all of the issues in this report correspondingly.
