About $27 million worth of positions have been lost in decentralized lending protocol Aave in the last 24 hours.
Market watchers said that this may be a temporary price barrier associated with token stack Ethereum (wstETH).
Data tracked by risk management firm Chaos Labs shows a sudden spike in liquidity, raising questions about whether price differences in Aave’s Oracle infrastructure may have misvalued collateral used in short-term loans.

Decentralized lending platforms like Aave rely heavily on price oracles, which feed real-world market data into blockchain applications.
These oracles help determine whether a borrower’s collateral is sufficient to repay their loan. If the value of the collateral falls below the required threshold, the position can be automatically removed.
In this case, some observers believe that the issue is related to wstETH, a token issued by Lido that represents the stake Ethereum (ETH) and receives a reward over time.
At the time of liquidity, the Aave risk oracle appeared to value WstETH at around 1.19 ETH, while the broader market price suggested the mark was closer to 1.23 ETH, according to an analysis shared by LTV Protocol on X.
This difference meant that the protocol temporarily treated the token as less valuable than it actually was, pushing some borrowing positions below their safety limits and creating liquidity.
Trading volume for wstETH remained relatively low during the event, around $10 million in the last 24 hours, making it unlikely that traders took advantage of the price gap before it corrected.
Chaos Labs later clarified that the real danger was the oracle itself working properly. Instead, the liquidity was created by a setting issue in Aave’s CAPO risk oracle system, which regulates how quickly yield-valued assets can increase in value.
The problem is caused by a mismatch between the old parameters stored in the smart contract, including the old reference exchange rate and its timing.
Because these values were not updated simultaneously, the CAPO system temporarily calculated a maximum exchange rate for wstETH that was lower than the actual market price.
