In the wake of a $292 million exploit, Aave and several prominent cryptocurrency firms have launched a collaborative recovery effort to shore up the decentralized finance (DeFi) market. The initiative, known as 'DeFi United', aims to restore the backing of rsETH, a yield-bearing ether (ETH) derivative token that was at the center of the hack.
Aave has announced that multiple participants have already committed to supporting the effort, with staking provider Lido Finance and EtherFi being among the first to offer aid. Lido Labs Foundation has proposed allocating up to 2,500 stETH, valued at approximately $5.7 million, to a dedicated relief fund. The funds will be used to reduce the shortfall in rsETH backing and 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 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 largest crypto exploit of the year, which sent shockwaves through DeFi lending markets. The incident occurred due to a vulnerability in KelpDAO's integration with LayerZero, allowing an attacker to mint 116,500 unbacked rsETH tokens.
The attacker then deposited nearly 90,000 rsETH into Aave as collateral, borrowing approximately $190 million in ETH and other assets. This left Aave with impaired collateral, triggering a rush of withdrawals and a $10 billion plunge in the total value of assets on the platform. The total shortfall 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 through a coordinated bailout to recapitalize rsETH and mitigate losses, rather than attempting to recover the stolen funds.
