Crypto Trader Loses $50M on AAVE Trade Due to High Slippage

A massive cryptocurrency trade using AAVE tokens and USDT stablecoins ended in disaster for a trader who lost tens of millions of dollars. The transaction, facilitated through CoW DAO, resulted in an unusually high slippage that left the user with only 324 AAVE tokens.

The Aave interface displayed clear warnings about the extreme price impact before the trade was completed, but the user confirmed the transaction on a mobile device, accepting the risk. 'Given the unusually large size of the single order, the Aave interface warned the user about extraordinary slippage and required confirmation,' said Stani Kulechov, founder of Aave.

High slippage occurs when a swap significantly exceeds available liquidity in decentralized finance, causing automated market-making mechanisms to raise prices as the trade progresses. In this case, the large order pushed the price far beyond expected levels, resulting in a significant loss for the trader.

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