In the aftermath of a $292 million exploit, Aave and several major cryptocurrency firms are working together to stabilize the decentralized finance (DeFi) market. The collaborative effort, 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 committed to supporting the initiative, with Lido Finance's ecosystem contributor, Lido Labs Foundation, being the first to propose allocating up to 2,500 stETH, valued at approximately $5.7 million, to a dedicated relief fund. This allocation is intended to reduce the shortfall in rsETH backing and prevent forced liquidations across lending markets.
Following Lido's proposal, EtherFi suggested 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 effort. 'Aave is my life's work, and we are working tirelessly to find the best possible outcome for our users,' Kulechov stated. 'I am committed to resolving this issue and normalizing market conditions as soon as possible.' Aave plans to announce additional commitments once they are formalized.
The DeFi United initiative comes in response to 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 by exploiting the bridge's messaging system.
Instead of selling the tokens, the attacker used nearly 90,000 rsETH as collateral on Aave, borrowing approximately $190 million in ETH and other assets across Ethereum and Arbitrum. This left Aave with impaired collateral, triggering a rush of withdrawals as lenders sought to retrieve available funds. The total value of assets on Aave plummeted by $10 billion in the wake of the incident. According to Aave's incident report, the total shortfall is estimated to be over 112,000 rsETH.
Prior to the DeFi United initiative, there were some early efforts to contain the damage. Earlier this week, Arbitrum's security council froze 30,766 ETH, worth roughly $71 million at the time, 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.
