In the aftermath of a devastating $292 million exploit, Aave has joined forces with major cryptocurrency firms to launch a concerted effort aimed at stabilizing the decentralized finance (DeFi) market. The collaborative initiative, dubbed 'DeFi United', seeks to restore the collateral backing of rsETH, a yield-bearing derivative token of ether (ETH) that was at the center of the security breach. 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, a contributor to Lido's 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 move was followed by EtherFi's proposal of a 5,000 ETH plan to 'protect users and prevent bad debt' across DeFi. Aave's founder, Stani Kulechov, has also 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 comes in response to the largest crypto exploit of the year, which has sent ripples across DeFi lending markets.
The incident was triggered by 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 rush of deposit withdrawals as lenders sought to withdraw available funds.
The total value of assets on Aave plummeted by $10 billion in the aftermath of 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 were some early containment efforts, including Arbitrum's security council freezing 30,766 ETH, worth approximately $71 million, tied to the exploit.
However, the remaining stolen funds were bridged and swapped into bitcoin via Thorchain, complicating recovery efforts. The current initiative focuses on stabilizing the system through a coordinated bailout, aiming to recapitalize rsETH and mitigate losses rather than attempting to recover the stolen funds.
