Aave and CoW Swap released drastically different post-incident analyses of a $50 million DeFi trading incident.

CoinFeed reported on March 16th that, according to The Block, Aave and CoW Swap released drastically different post-incident analyses over the weekend regarding the $50 million DeFi trading incident. On that day, a user used the CoW Swap widget on the Aave interface to exchange over $50 million worth of aEthUSDT for approximately $36,000 worth of aEthAAVE. Aave attributed the loss to an "illiquid market," emphasizing that users had manually confirmed 99.9% of price impact warnings and announced the deployment of the "Aave Shield" feature to block swaps with price impacts exceeding 25% by default. CoW Swap revealed a more complex cascading failure: a rigid gas cap caused better offers to be rejected, the optimal solver won two auctions but failed to execute, and the transaction may have been leaked from a private mempool.
