Balancer released comprehensive post-mortem of November 3 exploit that drained $121M from V2 Composable Stable Pools
Technical Root Cause:
- Incorrect rounding in exact-out swap calculations
- Required three conditions: rounding error, rate providers, and low liquidity
- Only affected specific V2 pools with BPT tokens and rate providers
Recovery Efforts Secured $45.7M:
- Emergency pool pauses protected $19.3M
- Whitehat rescues recovered $4.6M across chains
- StakeWise DAO emergency operation recovered $21.8M in osETH/osGNO
Key Response Timeline:
- 07:46 UTC: Attack detected, whitehats immediately front-ran on Ethereum
- 08:07 UTC: V6 pools paused, protecting vulnerable liquidity
- 11:01 UTC: Recovery mode activated for safe withdrawals
V3 Completely Unaffected:
- Different architecture with explicit rounding controls
- Consistent 18-decimal precision
- Formal verification prevented this attack vector
Migration Plan:
- V2 stable pool factory disabled
- BAL incentives stopped for affected pools
- Weighted and Gyro pools remain operational
- Comprehensive V3 migration guidance coming
Fund Recovery Process:
- Pool-by-pool basis, not socialized losses
- Active claiming required (no airdrops)
- Governance proposal needed for distribution
- Law enforcement coordination ongoing
