Aave, a prominent lending platform, has successfully raised approximately $160 million to mitigate the $200 million in bad debt resulting from the largest decentralized finance exploit of the year, as reported by Arkham on Saturday. The blockchain analytics platform stated, "Aave has raised $160M to cover the bad debt from the Kelp DAO exploit, via defiunited.eth. The largest contributors, Mantle and Aave DAO, have collectively raised 55,000 ETH, equivalent to $127M." Following a $292 million security breach that left the largest lender in the crypto borrowing sector facing a financial crisis, Aave and several major crypto firms launched a coordinated recovery effort to stabilize DeFi markets.
Dubbed DeFi United and led by Aave service providers, the initiative aims to restore support for rsETH, the yield-bearing derivative token of ether at the core of the exploit. Aave founder Stani Kulecho announced a personal contribution of 5,000 ETH to DeFi United, valued at approximately $11,730,000 at the current ether price of $2,346. The exploit was attributed to a vulnerability in the KelpDAO integration with LayerZero, where an attacker created 116,500 unbacked rsETH tokens, leaving Aave with impaired collateral and triggering a run on deposits as lenders rushed to exit, resulting in $10 billion in withdrawals.
The primary focus of the effort to eliminate the bad debt is on stabilizing the system through a coordinated bailout to recapitalize rsETH and minimize losses. This year's second-largest exploit occurred in late March, when an attacker drained at least $270 million from the Drift Protocol on Solana by exploiting a legitimate feature called 'durable nonces.'
