In the aftermath of a $292 million exploit, Aave and several prominent cryptocurrency firms have joined forces to launch a recovery effort aimed at stabilizing the decentralized finance (DeFi) market. The initiative, known as 'DeFi United', is led by Aave service providers and focuses on restoring the collateral backing of rsETH, a yield-bearing derivative token of ether (ETH) that was 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 aid. Lido Labs Foundation, an ecosystem contributor, 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 help 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's founder, Stani Kulechov, has contributed 5,000 ETH to the cause, stating that 'Aave is my life's work and we're working nonstop to find the best possible outcome for users.' The incident that prompted this response was the largest crypto exploit of the year, which sent shockwaves through DeFi lending markets. The exploit was made possible by a vulnerability in KelpDAO's integration with LayerZero, allowing an attacker to mint 116,500 unbacked rsETH tokens.

Instead of selling the tokens, the attacker used them 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 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 total shortfall is estimated to be over 112,000 rsETH.

Prior to the DeFi United initiative, there were some early attempts at containment, including the freezing of 30,766 ETH (worth roughly $71 million) by Arbitrum's security council. However, the majority of the stolen funds were bridged and swapped into bitcoin via Thorchain, making recovery more challenging. The current effort prioritizes stabilizing the system through a coordinated bailout, aiming to recapitalize rsETH and mitigate losses rather than attempting to recover the stolen funds.
