In the aftermath of a $292 million exploit, Aave and major cryptocurrency firms are joining forces to stabilize the decentralized finance (DeFi) market. The collaborative effort, dubbed 'DeFi United', aims to restore the collateral backing of rsETH, a yield-bearing ether (ETH) derivative token at the center of the exploit. Aave has announced that multiple participants have committed to supporting the initiative, with staking provider Lido Finance and EtherFi being among the first to offer aid. The proposals include allocating up to 2,500 stETH, valued at approximately $5.7 million, and a 5,000 ETH plan to safeguard users and prevent bad debt across DeFi.
Aave's founder, Stani Kulechov, has also pledged 5,000 ETH to support the recovery efforts. The initiative follows the largest crypto exploit of the year, which exposed 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 led to impaired collateral, triggering a rush of withdrawals and a $10 billion decline in Aave's total asset value.
The total shortfall is estimated to be over 112,000 rsETH, according to Aave's incident report. Prior to the DeFi United initiative, some containment efforts were made, including Arbitrum's security council freezing 30,766 ETH tied to the exploit.
However, the remaining stolen funds were bridged and swapped into bitcoin via Thorchain, complicating recovery efforts. 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.
