Crypto trader loses over $49 million due to AAVE swap error

A user swapped 50.4 million USDT for 324 AAVE worth about $36,200 through the Aave interface, agreeing to an extremely high 99% slippage despite warnings. As a result, most of the funds went to the block builder Titan, who gained more than $34 million in profit. The Aave team is now trying to contact the trader to at least recover the $600,000 commission fee.

This transaction highlights the critical importance of paying close attention to swap conditions in DeFi, especially slippage tolerance. The trader’s mistake led to a massive loss that proved profitable for the block builder. Meanwhile, Aave is taking steps to reach out to the user and resolve the issue, which has drawn significant attention within the platform’s community.

Such incidents may raise awareness of DeFi risks and encourage the adoption of stricter security measures across protocols.
