Summarized the recent $50M transaction mishap on Aave. (via CoW Swap) Although this is the most severe transaction execution loss in DeFi history, the way it happened is super strange. First off, CoW's anti-MEV mechanism pretty much failed. Given AAVE's current on-chain liquidity, swapping back $5M worth of AAVE should've been no problem, but the execution ended up being routed to the worst-depth Sushi pool, which only had $70K in liquidity.
