A user who bought AAVE lost over $50 million due to slippage.

On March 13th, user @kingfxyo attempted to exchange approximately $50.43 million worth of aEthUSDT for AAVE via CoWSwap. Due to slippage exceeding 99%, they ultimately received only about 327 aEthAAVE, worth approximately $36,000. Community analysis suggests that this exchange was likely executed through AAVE's UI using the collateral exchange function, converting aEthUSDT for aEthAAVE, which means depositing USDT and AAVE into the AAVE protocol. The problem is primarily attributed to the poor routing strategies employed by most aggregators; CoWSwap does not appear to have misrepresented the price of aEthAAVE.
