In the wake of a devastating $292 million hack, Aave has teamed up with major cryptocurrency firms to launch a stabilization effort aimed at restoring the integrity of decentralized finance (DeFi) markets. The collaborative initiative, dubbed 'DeFi United', seeks to bolster the backing of rsETH, a yield-bearing ether (ETH) derivative token at the epicenter 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, while EtherFi has suggested a 5,000 ETH plan to 'safeguard users and prevent toxic debt' across DeFi. Aave founder Stani Kulechov has also pledged 5,000 ETH, stating that 'Aave is my life's work and we're working tirelessly to find the best possible outcome for users.' The initiative aims to reduce the shortfall in rsETH backing, prevent forced liquidations, and stabilize lending markets.

The exploit, which occurred due to a vulnerability in KelpDAO's integration with LayerZero, resulted in the attacker minting 116,500 unbacked rsETH tokens. The attacker then deposited nearly 90,000 rsETH into Aave as collateral, borrowing approximately $190 million in ETH and other assets.

This triggered a run on deposits, with lenders rushing to withdraw available funds, and the total value of assets on Aave plummeting by $10 billion. 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 tied to the exploit.

However, the remaining stolen funds were bridged and swapped into bitcoin via Thorchain, complicating recovery efforts. The current initiative focuses on stabilizing the system through a coordinated bailout, aiming to recapitalize rsETH and mitigate losses rather than attempting to recover the stolen funds.
