Aave Introduces Aave Shield After $50 Million DeFi Swap Loss

Aave plans to launch a new protection feature called Aave Shield after a trader lost over $50 million during a large token swap affected by liquidity constraints.

Decentralized finance protocol Aave said it will introduce a new protection mechanism called Aave Shield following a token swap incident that resulted in a loss of more than $50 million. The feature is designed to prevent users from executing trades with extreme price impact through the Aave interface.

The incident occurred when a trader attempted to swap approximately $50.4 million worth of USDT for AAVE using decentralized exchange infrastructure integrated into the Aave interface. Due to limited market liquidity, the transaction returned only about $36,500 worth of AAVE tokens. The price impact, combined with infrastructure issues and a sandwich attack from a maximal extractable value bot, resulted in a loss exceeding $50 million.

Aave Shield will automatically block swaps with price impact above 25%. Users will still be able to bypass the protection manually, but the default safeguard aims to reduce the risk of severe trading losses. eams behind both Aave and CoW Swap said they are continuing to investigate the infrastructure failures that contributed to the trade execution issue.
