$50M AAVE Trade Disaster: High Slippage Leaves Trader with Minimal Token Return

A cryptocurrency trader lost $50 million in what is being called the worst AAVE trade ever recorded, after executing a high-slippage transaction that returned only 324 tokens. The trade was executed through the Aave interface and routed via CoW DAO, triggering warnings before completion due to the unusually large order size.

The trader confirmed the transaction on a mobile device despite clear alerts about the extreme price impact and required risk acknowledgment. High slippage occurs when a swap significantly exceeds available liquidity, causing the algorithm to raise the price as the trade progresses, resulting in a sharply divergent final execution price from the initial quote.

Aave founder Stani Kulechov stated that the transaction could not have been completed without the trader explicitly confirming the risk through the interface warning. CoW DAO said there was no evidence of an exploit or malicious activity, with the platform noting that such events can occur in decentralized finance and transactions of this magnitude are rare.

Aave plans to refund approximately $600,000 in fees generated by the trade while attempting to contact the affected user.
