Aave, a lending platform, has successfully raised approximately $160 million to address 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, facilitated through defiunited.eth. Notably, the largest contributors, Mantle and AAVE DAO, have together contributed 55,000 ETH, equivalent to $127M." In response to a $292 million security breach that left Aave facing a financial crisis, the company and several major cryptocurrency firms launched a coordinated recovery effort last week to stabilize DeFi markets. Led by Aave service providers, the initiative, known as DeFi United, aims to restore support for rsETH, the yield-bearing derivative token of ether at the center of the exploit.
Aave founder Stani Kulecho announced his personal contribution of 5,000 ETH to DeFi United, valued at approximately $11,730,000 at the current ether price of roughly $2,346. The exploit was linked to a vulnerability in KelpDAO's integration with LayerZero, where an attacker created 116,500 unbacked rsETH tokens, resulting in impaired collateral for Aave and triggering a massive withdrawal of $10 billion as lenders rushed to exit. 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.
Earlier this year, the second-largest exploit occurred in late March, when an attacker exploited the Drift Protocol on Solana, abusing a feature called 'durable nonces' to drain at least $270 million, rather than exploiting a code bug or stolen keys.
