In the aftermath of a $292 million exploit that has left a significant collateral shortfall, Aave and major cryptocurrency firms are collaborating on a recovery effort, dubbed 'DeFi United', aimed at stabilizing the decentralized finance (DeFi) market. The initiative focuses on replenishing the backing of rsETH, a yield-bearing ether (ETH) derivative token at the center of the exploit. Aave has announced that several participants have already committed to supporting the effort, with Lido Finance's ecosystem contributor, Lido Labs Foundation, proposing to allocate up to 2,500 stETH, valued at approximately $5.7 million, to a dedicated relief fund.
EtherFi has also proposed a plan involving 5,000 ETH to protect users and prevent bad debt across DeFi. Aave's founder, Stani Kulechov, has pledged a 5,000 ETH contribution, stating that 'Aave is my life's work and we're working nonstop to find the best possible outcome for users.' The initiative comes in response to the largest crypto exploit of the year, which has sent shockwaves through DeFi lending markets. The exploit was caused by a vulnerability in KelpDAO's integration with LayerZero, allowing an attacker to mint 116,500 unbacked rsETH tokens. The attacker then deposited nearly 90,000 rsETH into Aave as collateral, borrowing around $190 million in ETH and other assets.
This has resulted in impaired collateral, triggering a rush of withdrawals and a $10 billion plunge in the total value of assets on Aave. 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 the freezing of 30,766 ETH by Arbitrum's security council.
However, the remaining stolen funds were bridged and swapped into bitcoin via Thorchain, making recovery more complex. The current effort prioritizes stabilizing the system through a coordinated bailout to recapitalize rsETH and mitigate losses, rather than attempting to recover the stolen funds.
