EulerSwap

Summary

The most critical subjects covered in our audit are functional correctness, precision of arithmetic operations, and front-running. Security regarding all the aforementioned subjects is good but improvable, see Unaccounted roundings when depositing and withdrawing and Balance of Euler account counted twice in calcLimits(). Notice that Euler decided not to fix some of the issues for the time being; these issues have been marked Acknowledged .

The general subjects covered are code complexity, gas efficiency, and trust relationships. Security regarding all the aforementioned subjects is high.

In summary, we find that the codebase provides a good level of security, which could be improved if all the outstanding issues were to be addressed.

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.
