In the aftermath of a $292 million exploit, Aave and several prominent cryptocurrency firms have joined forces to launch a recovery effort, aiming to stabilize the decentralized finance (DeFi) market. The initiative, known as 'DeFi United', is led by Aave service providers and focuses on restoring 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 pledged their support for the effort. Lido Finance, a staking provider, was among the first to commit, with its ecosystem contributor, Lido Labs Foundation, proposing to allocate up to 2,500 stETH (approximately $5.7 million at current prices) to a dedicated relief fund.
The funds will be utilized to reduce the shortfall in rsETH backing and help prevent forced liquidations across lending markets. This was followed by EtherFi's proposal of a 5,000 ETH plan to 'protect users and prevent bad debt' across DeFi. Stani Kulechov, founder of Aave, has also offered a 5,000 ETH contribution. In a statement, Kulechov expressed his commitment to finding the best possible outcome for users, stating, 'Aave is my life's work, and we're working nonstop to resolve this issue and normalize market conditions as soon as possible.' Aave plans to announce additional commitments once they have been 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 originated from 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 deposited nearly 90,000 rsETH into Aave as collateral, borrowing approximately $190 million in ETH and other assets across Ethereum and Arbitrum. This left Aave with impaired collateral, triggering a rush of deposit withdrawals as lenders sought to retrieve available funds.
The total value of assets on Aave plummeted by $10 billion following 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 containment efforts.
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, aiming to recapitalize rsETH and mitigate losses rather than attempting to recover the stolen funds.
