In the aftermath of a $292 million exploit, Aave and several prominent cryptocurrency firms have banded together to launch a recovery effort aimed at stabilizing the decentralized finance (DeFi) market. The initiative, known as 'DeFi United' and spearheaded by Aave service providers, seeks to restore the collateral backing of rsETH, a yield-bearing ether (ETH) derivative token at the center of the exploit. Aave has announced that multiple participants have already committed to supporting the effort, with staking provider Lido Finance being among the first to pledge its support. Lido Labs Foundation, a contributor to the Lido ecosystem, has proposed allocating up to 2,500 stETH, valued at approximately $5.7 million, to a dedicated relief fund.
The funds will be utilized to reduce the shortfall in rsETH backing and prevent forced liquidations across lending markets. This was followed by EtherFi's proposal of a 5,000 ETH plan to 'protect users and prevent bad debt' across DeFi.
Aave founder Stani Kulechov has also offered a 5,000 ETH contribution, stating, 'Aave is my life's work, and we are working tirelessly to achieve the best possible outcome for users.' The initiative comes in response to the biggest crypto exploit of the year, which has sent shockwaves through DeFi lending markets. The incident originated from a vulnerability in KelpDAO's integration with LayerZero, where an attacker exploited the bridge's messaging system to mint 116,500 unbacked rsETH tokens.
Instead of selling the tokens, the attacker deposited nearly 90,000 rsETH into Aave as collateral, borrowing approximately $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.
The total value of assets on Aave plummeted by $10 billion following the incident. According to Aave's incident report, the total shortfall is estimated to be over 112,000 rsETH.
Prior to the DeFi United initiative, there have been some early containment efforts. Earlier this week, Arbitrum's security council froze 30,766 ETH, worth roughly $71 million at the time, 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 through a coordinated bailout to recapitalize rsETH and mitigate losses, rather than attempting to recover the stolen funds.
