In the aftermath of a devastating $292 million exploit, Aave and several prominent crypto firms have launched a collaborative recovery initiative to stabilize the decentralized finance (DeFi) market. The effort, dubbed 'DeFi United', aims to restore the collateral backing of rsETH, a yield-bearing ether (ETH) derivative token at the center of the hack. Aave has announced that multiple participants have already pledged their support, with staking provider Lido Finance's ecosystem contributor, Lido Labs Foundation, proposing to allocate up to 2,500 stETH (approximately $5.7 million) to a relief fund. This move is designed 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 committed 5,000 ETH to the cause, stating that 'Aave is my life's work and we're working tirelessly to find the best possible outcome for users.' The initiative follows the largest crypto exploit of the year, which exposed a vulnerability in KelpDAO's integration with LayerZero. An attacker exploited the bridge's messaging system to mint 116,500 unbacked rsETH tokens, depositing nearly 90,000 into Aave as collateral and borrowing approximately $190 million in ETH and other assets. This triggered a run on deposits, with lenders rushing to withdraw available funds, resulting in a $10 billion decline in Aave's total asset value.
The estimated total shortfall stands at over 112,000 rsETH, according to Aave's incident report. Prior to the DeFi United initiative, some early containment efforts were made, including Arbitrum's security council freezing 30,766 ETH (worth roughly $71 million) linked to the exploit. However, the remaining stolen funds were bridged and swapped into bitcoin via Thorchain, complicating recovery efforts.
The current focus is on stabilizing the system through a coordinated bailout to recapitalize rsETH and mitigate losses, rather than attempting to recover the stolen funds.
