A single Aave interface user lost $50M on a CoWSwap-routed AAVE swap after Aave Labs replaced its ParaSwap integration in December 2025 without carrying over the 30% slippage cap. The solver routed a $50M trade through a $73K liquidity pool. A block builder captured $34.3M; MEV bots took ~$12.5M. Aave collected $110,368 in fees and pledged to return them pending verification.
