What Auditors Should Check

Audited by Audit Report 1 — still lost $18.4M. Prior audits don't guarantee safety, especially after post-audit code changes.

If you're auditing a protocol with similar architecture to Rhea Finance, these are the critical security checks that could have prevented this incident (April 2026).

Review privileged functions (owner, admin, governance) for potential abuse vectors - centralization risks should be documented and bounded with timelocks or multi-sigs
