A 2.85% Minor Deviation, $27 Million in Liquidations: The Full Story of the Aave Price Oracle Incident
A brief 2.85% pricing deviation in wstETH collateral on Aave triggered approximately $27 million in liquidations. The incident occurred because Aave's risk oracle module (CAPO) used outdated parameters, temporarily valuing wstETH at around 1.19 ETH instead of its market price of ~1.23 ETH. This made some borrowing positions appear under-collateralized, activating the protocol's automatic liquidation system.
While the event highlighted the fragility of DeFi oracle systems and how minor technical misconfigurations can lead to significant financial consequences, no bad debt was incurred by the Aave protocol itself. The core issue was not a failure of the primary price oracle or the wstETH token, but an internal configuration error within Aave's additional risk management layer. The incident underscores the critical importance of reliable oracle infrastructure and precise parameter synchronization in decentralized finance.
