In response to a $292 million exploit that has left a significant gap in collateral backing, Aave and several prominent crypto firms are spearheading a coordinated recovery effort to stabilize the decentralized finance (DeFi) market. The initiative, known as 'DeFi United', aims to restore the backing of rsETH, a yield-bearing ether (ETH) derivative token at the center of the exploit. Aave has announced 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, to 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 Aave founder Stani Kulechov has pledged a 5,000 ETH contribution. According to Kulechov, 'Aave is my life's work, and we are working tirelessly to find the best possible outcome for users.' The initiative follows the largest crypto 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.
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 withdrawals as lenders sought to access available funds. The total value of assets on Aave plummeted by $10 billion in the aftermath of the incident.
Although early containment efforts have been made, including the freezing of 30,766 ETH worth roughly $71 million by Arbitrum's security council, the remaining stolen funds were bridged and swapped into bitcoin via Thorchain, making recovery more complicated. 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.
