Aave and CoW Swap Disagree on Causes of $50 Million Losses in Slippage Incident

Aave and CoW Swap have published conflicting reports on an incident they describe as a flash loan attack resulting in $50 million in losses. Aave believes the cause was insufficient market liquidity: user orders exceeded available volume, and CoW Swap offered a price 99.9% below expected, which users confirmed. CoW Swap, in turn, pointed to outdated gas limits, missing transactions from the winning solver, and possible transaction leakage from the private mempool, emphasizing that a single security flag is insufficient.
