In response to a $292 million exploit that has left a significant collateral shortfall, Aave and several prominent crypto companies are collaborating on a recovery effort to stabilize the decentralized finance (DeFi) market. The initiative, known as 'DeFi United', is led by Aave service providers and aims to restore the backing of rsETH, a yield-bearing derivative token of ether (ETH), which is at the center of the exploit. Aave has announced that multiple participants have already committed to supporting the effort, with Lido Finance being the first to propose allocating up to 2,500 stETH, valued at approximately $5.7 million, to a dedicated relief fund.
This will help 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, while Aave founder Stani Kulechov has pledged a 5,000 ETH contribution.
Kulechov stated, 'Aave is my life's work, and we are working tirelessly to find the best possible outcome for users. I am committed to resolving this issue and normalizing market conditions as soon as possible.' Aave plans to announce additional commitments once they are formalized. The initiative follows the largest crypto exploit of the year, which has sent shockwaves through DeFi lending markets.
The incident was caused by a vulnerability in KelpDAO's integration with LayerZero, where an attacker minted 116,500 unbacked rsETH tokens by exploiting the bridge's messaging system. 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 withdrawals as lenders sought to retrieve available funds. The total value of assets on Aave plummeted by $10 billion following the incident.
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 approximately $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.
