In response to a $292 million exploit that has left a significant dent in the collateral backing of decentralized finance (DeFi) markets, Aave has collaborated with several prominent crypto firms to establish a recovery effort. Dubbed 'DeFi United', this initiative aims to restore the backing of rsETH, a yield-bearing derivative token of ether (ETH) that is central to the exploit. Aave has announced that multiple participants have already pledged their support for the effort, with Lido Finance's ecosystem contributor, Lido Labs Foundation, being the first to propose allocating up to 2,500 stETH, valued at approximately $5.7 million, to a dedicated relief fund. This allocation is intended to reduce the shortfall in rsETH backing and prevent forced liquidations across lending markets.
EtherFi has also proposed a 5,000 ETH plan to safeguard users and prevent bad debt across DeFi. Aave's founder, Stani Kulechov, has personally offered 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 has sent shockwaves throughout DeFi lending markets.
The incident is attributed to 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 used nearly 90,000 rsETH as collateral to borrow approximately $190 million in ETH and other assets across Ethereum and Arbitrum, leaving Aave with impaired collateral and triggering a rush of deposit withdrawals. The total value of assets on Aave plummeted by $10 billion in the aftermath of the incident.
According to Aave's incident report, the estimated total shortfall is over 112,000 rsETH. Prior to the DeFi United initiative, some early containment efforts were made, including Arbitrum's security council freezing 30,766 ETH, valued at roughly $71 million, tied to the exploit. However, the remaining stolen funds were bridged and swapped into bitcoin via Thorchain, complicating the recovery process. 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.
