In response to a $292 million exploit that has left a significant shortfall in collateral backing, Aave and several major crypto firms are working together to stabilize the decentralized finance (DeFi) market through a coordinated recovery effort dubbed 'DeFi United'. This initiative, 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. EtherFi has also proposed a 5,000 ETH plan to protect users and prevent bad debt across DeFi.
Aave founder Stani Kulechov has pledged a 5,000 ETH contribution, stating that finding the best possible outcome for users is a top priority. The initiative comes after the largest crypto exploit of the year sent shockwaves through DeFi lending markets, resulting from a vulnerability in KelpDAO's integration with LayerZero.
An attacker exploited the bridge's messaging system to mint 116,500 unbacked rsETH tokens, depositing nearly 90,000 rsETH into Aave as collateral and borrowing around $190 million in ETH and other assets. This led to impaired collateral, triggering a rush of withdrawals and a $10 billion plunge in the total value of assets on Aave. With an estimated total hole of over 112,000 rsETH, according to Aave's incident report, 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.
