Aave, a decentralized lending platform, has successfully raised approximately $160 million to mitigate the $200 million in bad debt resulting from the largest DeFi exploit of the year, as reported by Arkham on Saturday. The blockchain analytics platform stated, "To date, AAVE has raised $160M to cover the bad debt from the Kelp DAO Exploit, facilitated through defiunited.eth. The primary 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 prominent crypto firms announced a coordinated recovery effort to stabilize DeFi markets last week. Led by Aave service providers, the initiative, dubbed DeFi United, aims to restore support for rsETH, the yield-bearing derivative token of ether (ETH) at the core of the exploit.
Aave's 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, which was traced back to a vulnerability in KelpDAO's integration with LayerZero, resulted in an attacker minting 116,500 unbacked rsETH tokens, ultimately leaving Aave with impaired collateral and triggering a significant withdrawal of $10 billion.
The primary focus of the effort to eliminate the bad debt is on stabilizing the system through a coordinated bailout, aimed at recapitalizing rsETH and mitigating losses. This incident is the largest DeFi exploit of the year, surpassing the second-largest exploit in late March, where an attacker drained at least $270 million from the Drift Protocol on Solana by exploiting a legitimate feature called 'durable nonces'.
