Aave and several major cryptocurrency companies are collaborating on a recovery effort to stabilize the decentralized finance (DeFi) market following a $292 million exploit that left the sector's largest lender facing a significant shortfall in collateral. The initiative, dubbed 'DeFi United' and led by Aave service providers, aims to restore the backing of rsETH, a yield-bearing derivative token of ether (ETH), at the center of the exploit. Multiple participants have already committed to supporting the effort, with staking provider Lido Finance's ecosystem contributor Lido Labs Foundation proposing to allocate up to 2,500 stETH, worth approximately $5.7 million, into a dedicated relief vehicle. This would help reduce the shortfall in rsETH backing 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 offered a 5,000 ETH contribution. The exploit, which is the largest cryptocurrency heist of the year, has sent shockwaves through DeFi lending markets. It originated from a vulnerability in KelpDAO's integration with LayerZero, where an attacker minted 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 around $190 million in ETH and other assets. This has left Aave with impaired collateral, triggering a rush of withdrawals and a $10 billion plunge in the total value of assets on the platform. 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.
