Lending protocol Aave has brought wrapped ether (WETH) collateral rates, which were tightened after the abuse that occurred in April and caused serious losses, back to their previous levels on six major blockchain networks. Aave is known as one of the widely used lending and borrowing protocols in the decentralized finance (DeFi) world and enables loan buying and selling by collateralizing various digital assets.
WETH’s Critical Role Reinforced
As a tokenized form of ether, WETH serves as liquid collateral in DeFi applications. In April, approximately $292 million worth of non-fungible tokens were generated as a result of a hyperlink attack linked to the Kelp DAO’s yield-generating rsETH token. Using these tokens as collateral, $230 million worth of ETH was withdrawn from Aave, causing great damage to the protocol.
During the incident, Aave management reduced WETH’s collateral rate to 0 percent as an emergency measure, so investors could not borrow using WETH as collateral. While this decision aimed to limit systemic risks, it also seriously narrowed liquidity and leverage use in DeFi markets.
Normalization in Collateral Rates
According to documents published by Aave management, the rates before the incident are now re-applied. Accordingly, the collateral rate was updated to 80.5 percent in Ethereum Core, 84 percent in Ethereum Prime, 80 percent in Arbitrum, 80.5 percent in Base, 80.5 percent in Mantle and 80 percent in Linea.
The fact that collateral rates have been reduced to previous levels indicates that Aave believes that the risks in the market are significantly under control. However, there are still uncertainties regarding legal processes and liability regarding frozen assets.
In total, approximately 112,103 unrequited rsETH was generated in the exploit. 89,567 of these were via Aave; A total of 106,993 of them were recovered, 17,426 of which were through the Compound protocol. The remaining approximately 5,200 rsETH gap is expected to be closed by the industry’s leading DeFi United coalition.
Effect on Markets
WETH is considered one of the mainstays of trading with leverage and creating liquidity in DeFi markets. The fact that WETH could not be used as collateral due to emergency measures caused users to not be able to utilize their capital efficiently and create additional liquidity.
Now, granting WETH secured borrowing opportunity again is seen as a signal of normalization in the market. This step is especially valuable for investors who need to borrow money in terms of reusing leverage and liquidity strategies.
At the same time, this development stands out as an important example of how protocols across the DeFi ecosystem intervene against attacks and how crisis management processes are carried out. All eyes are now on how the missing assets will be compensated and how the systemic risk discussions in the markets will evolve.
