Omniscia Mean Finance Audit
Swappers Module Security Audit
Audit Overview
We were tasked with performing an audit of the Mean Finance codebase and in particular their swapper module implementation meant to expose a single-point-of-contact for all swaps performed across the Mean Finance system.
Over the course of the audit, we identified several ways code maintenance can be optimized as well as certain code paths that could lead to ill user experience and loss of funds if mis-used.
We advise the Mean Finance team to closely evaluate all minor-and-above findings identified in the report and promptly remediate them as well as consider all optimizational exhibits identified in the report.
Post-Audit Conclusion
The Mean Finance team provided us with a document that addresses all exhibits outlined in the report and provides rationale as to why certain exhibits were acknowledged.
We evaluated the latest commit hash provided to us by the Mean Finance team and assessed that all findings have been adequately dealt with.

During the audit, we filtered and validated a total of 1 findings utilizing static analysis tools as well as identified a total of 15 findings during the manual review of the codebase. We strongly recommend that any minor severity or higher findings are dealt with promptly prior to the project's launch as they introduce potential misbehaviours of the system as well as exploits.
