In the aftermath of a $292 million exploit, Aave and several prominent crypto companies have launched a collaborative recovery effort, dubbed 'DeFi United', to restore stability to decentralized finance (DeFi) markets and address the significant collateral shortfall. The initiative, led by Aave service providers, focuses on replenishing 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 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 will help reduce the rsETH backing deficit and prevent forced liquidations across lending markets. EtherFi has also 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.

'Aave is my life's work, and we are working tirelessly to find the best possible outcome for 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 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 on Aave, borrowing approximately $190 million in ETH and other assets across Ethereum and Arbitrum.

This resulted in impaired collateral, triggering a rush of withdrawals and a $10 billion decline in Aave's total asset value. The estimated total shortfall is over 112,000 rsETH, according to Aave's incident report. Prior to the DeFi United initiative, some early containment efforts were made, including Arbitrum's security council freezing 30,766 ETH, worth around $71 million, tied to the exploit.

However, the remaining stolen funds were bridged and swapped into bitcoin via Thorchain, complicating recovery efforts. The current focus is on stabilizing the system through a coordinated bailout, aimed at recapitalizing rsETH and mitigating losses, rather than attempting to recover the stolen funds.
