The March 13 Aave collateral swap routed through Uniswap V3 and a shallow SushiSwap pool, highlighting how poor liquidity and MEV extraction can amplify losses in DeFi trades.
A user lost about $50.4 million after swapping 50.43 million USDT into AAVE through Aave’s collateral swap feature on March 13, receiving only about $36,100 in AAVE. The trade was routed through Uniswap V3 and a shallow SushiSwap AAVE/WETH pool, causing extreme slippage. According to the new report, MEV builders, searchers, liquidity providers, and validators captured most of the lost value. The update adds execution-path details to the previously reported incident and further underscores liquidity and transaction-routing risks in DeFi.
