In the aftermath of a $292 million exploit, Aave and several prominent crypto firms have launched a collaborative recovery effort to shore up decentralized finance (DeFi) markets. The initiative, known as '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 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.
This would help 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. Kulechov stated, 'Aave is my life's work, and we're working tirelessly to find the best possible outcome for users.' The initiative follows the largest crypto exploit of the year, which 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 used nearly 90,000 rsETH as collateral to borrow approximately $190 million in ETH and other assets across Ethereum and Arbitrum, leaving Aave with impaired collateral and triggering a rush of deposit withdrawals.
The total value of assets on Aave plummeted by $10 billion in the aftermath. With an estimated total shortfall of over 112,000 rsETH, according to Aave's incident report, the DeFi United initiative prioritizes stabilizing the system through a coordinated bailout to recapitalize rsETH and mitigate losses, rather than focusing on recovering the stolen funds.
