Aave and several prominent cryptocurrency firms have joined forces to launch a recovery effort aimed at stabilizing the decentralized finance (DeFi) market, following a $292 million exploit that left a significant collateral shortfall in the sector's largest lender. The initiative, known as 'DeFi United' and led by Aave service providers, seeks to restore the backing of rsETH, a yield-bearing ether (ETH) derivative token at the center of the exploit. Multiple participants have already committed to supporting the effort, according to Aave.
Lido Finance's ecosystem contributor, Lido Labs Foundation, was among the first to pledge support, proposing to allocate up to 2,500 stETH, valued at approximately $5.7 million, to a dedicated relief fund. The funds will be used to reduce the rsETH backing shortfall and prevent forced liquidations across lending markets. EtherFi subsequently proposed a 5,000 ETH plan to 'protect users and prevent bad debt' across DeFi, while Aave founder Stani Kulechov offered a 5,000 ETH contribution. 'Aave is my life's work, and we're working tirelessly to find the best possible outcome for users,' Kulechov stated.
'I'm working to resolve this issue and normalize market conditions as soon as possible.' Aave plans to announce additional commitments once formalized. The initiative follows the largest crypto exploit of the year, which sent shockwaves through DeFi lending markets. The incident originated from 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 run on deposits as lenders rushed to withdraw available funds.
The total value of assets on Aave plummeted by $10 billion following the incident. The estimated total shortfall is 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 roughly $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.
