Someone lost ~36 million swapping aUSDT to aAAVE on @CoWSwap . It's not even a sandwich... just a pure arbitrage. I don't think it's either @aave 's or @CoWSwap 's problem. The user swaps 50 million aUSDT to aAAVE on chain and there's no enough liquidity. Even if the user uses USDT -> AAVE (not wrapped aToken), the liquidity is still the same so such large swaps should be done twap / via OTC. Not atomically on chain. Cow swap front end is showing proper warnings. P1: victim: 0x98B9D979C33dD7284C854909BCC09b51FBF97Ac8, txhash: 0x9fa9feab3c1989a33424728c23e6de07a40a26a98ff7ff5139f3492ce430801f P2: arbitrage transaction, with a bribe of 26 million (arbitrage net profit ~9 million).

@CoWSwap @aave Interestingly, the arbitrager used liquidity from bancor (@Bancor) which the swap didn't use. The entire block consists of multiple arbitrages related to this swap.

@CoWSwap @aave @Bancor *Correction: Almost the entire 50 million were lost and captured by arbitragers.
