In the aftermath of a $292 million exploit that has left a significant gap in collateral, Aave and several prominent crypto firms have come together to launch a coordinated recovery effort aimed at stabilizing the decentralized finance (DeFi) markets. The initiative, known as 'DeFi United', is focused on restoring the backing of rsETH, a yield-bearing derivative token of ether (ETH), which is at the center of the exploit. Aave has announced that multiple participants have already committed to supporting the effort, with the first being Lido Finance, which has proposed allocating up to 2,500 stETH, valued at approximately $5.7 million, into a dedicated relief fund.
This fund would be used to reduce the shortfall in rsETH backing and help prevent forced liquidations across lending markets. EtherFi has also proposed a 5,000 ETH plan to protect users and prevent bad debt across DeFi.
Aave's founder, Stani Kulechov, has pledged a 5,000 ETH contribution, stating that 'Aave is my life's work and we're working nonstop to find the best possible outcome for users.' The initiative follows the biggest crypto exploit of the year, which has sent shockwaves through DeFi lending markets. The incident occurred due to a vulnerability in KelpDAO's integration with LayerZero, where an attacker minted 116,500 unbacked rsETH tokens by exploiting the bridge's messaging system.
Instead of selling the tokens, the attacker deposited nearly 90,000 rsETH into Aave as collateral, borrowing around $190 million in ETH and other assets across Ethereum and Arbitrum. This left Aave with impaired collateral, triggering a run on deposits as lenders rushed to withdraw available funds, resulting in a $10 billion plunge in the total value of assets on Aave. The total hole is estimated to be over 112,000 rsETH, according to Aave's incident report.
Prior to the DeFi United initiative, there were some early containment efforts, including Arbitrum's security council freezing 30,766 ETH, worth roughly $71 million, tied to the exploit. However, the remaining stolen funds were bridged and swapped into bitcoin via Thorchain, making recovery more complex. The current effort focuses on stabilizing the system with a coordinated bailout to recapitalize rsETH and mitigate losses, rather than attempting to recover the stolen funds.
