In response to a $292 million exploit that has left a substantial shortfall in collateral backing, Aave and several prominent cryptocurrency firms are collaborating on a recovery effort to stabilize the decentralized finance (DeFi) market. The initiative, known as 'DeFi United' and led by Aave service providers, aims to restore the backing of rsETH, a yield-bearing derivative token of ether (ETH) that is central to the exploit. Aave has indicated that multiple participants have already committed to supporting the effort, with staking provider Lido Finance and EtherFi being among the first to offer aid. Lido Labs Foundation has proposed allocating up to 2,500 stETH, valued at approximately $5.7 million, into a dedicated relief fund to reduce the shortfall in rsETH backing and prevent forced liquidations across lending markets.
Additionally, EtherFi has proposed a 5,000 ETH plan to 'protect users and prevent bad debt' across DeFi, while Stani Kulechov, founder of Aave, has offered 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 further commitments once they are formalized. The initiative follows the largest cryptocurrency exploit of the year, which has sent shockwaves through DeFi lending markets. The incident occurred due to a vulnerability in KelpDAO's integration with LayerZero, allowing an attacker to mint 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 has left Aave with impaired collateral, triggering a rush of deposit withdrawals and a $10 billion plunge in the total value of assets on Aave.
The estimated total shortfall is over 112,000 rsETH, according to Aave's incident report. Prior to the DeFi United initiative, there have been 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.
