What the Attacker Needed to Succeed
Understanding the prerequisites for this type of attack helps auditors identify protocols that are most at risk and helps developers build better defenses.
What Auditors Should Check
If you're auditing a protocol with similar architecture to Blend Pools V2, these are the critical security checks that could have prevented this incident (February 2026).
- Verify all logic paths related to Price Oracle Manipulation are guarded by proper access controls and input validation - see the Oracle Manipulation & Price Manipulation attack class for patterns
- Audit oracle price feeds for manipulation risks - ensure time-weighted average prices (TWAPs) or multi-source aggregators are used, not spot prices
- Review privileged functions (owner, admin, governance) for potential abuse vectors - centralization risks should be documented and bounded with timelocks or multi-sigs
