Key Takeaways
Aave has restored normal loan-to-value (LTV) ratios for wrapped ether on six networks, signaling the immediate crisis from a $230 million exploit in April has passed after a successful recovery of more than 95 percent of the unbacked assets. The move reverses emergency measures that had disabled WETH as collateral on the DeFi lending platform.
The decision marks a return to normal operations for one of DeFi's most critical collateral assets. According to Aave governance documents, WETH LTVs returned to levels as high as 84 percent on networks including Ethereum, Arbitrum, Base, and Mantle. The emergency settings had previously cut the LTV to zero percent to contain the fallout.
The crisis began when an attacker exploited a LayerZero bridge misconfiguration to mint approximately $292 million in unbacked rsETH, a liquid restaking token from Kelp DAO. Those tokens were then deposited as collateral on Aave to drain about $230 million of ether (ETH). The incident highlighted how bridge vulnerabilities can directly translate into credit market failures.
Restoring WETH's borrowing utility reopens a core financing channel for DeFi users and improves capital efficiency across the ecosystem. The recovery effort has reclaimed 106,993 of the 112,103 unbacked rsETH tokens through a combination of on-chain liquidations on Aave and Compound, with an industry coalition named DeFi United expected to cover the remaining 5,200 rsETH shortfall.
While the restoration signals confidence from Aave's risk managers, the exploit serves as a lesson on the systemic risks of cross-chain infrastructure. The incident proved that when an unbacked asset is accepted as collateral, the lending protocol can become the monetization point for a bridge failure, making cross-chain integrity a crucial part of the DeFi credit risk stack.
