Aave has initiated the "DeFi United" rescue effort in response to the $292 million losses from the KelpDAO hack, which exploited a vulnerability in the LayerZero integration. The attack allowed hackers to create uncollateralized rsETH and borrow approximately $190 million in assets on Aave, leading to a significant drop in the platform's total value locked (TVL) by about $10 billion. In collaboration with institutions like Lido Finance and EtherFi, Aave is focusing on capital injections to stabilize the DeFi lending ecosystem. While Arbitrum has managed to freeze some funds, the majority have been moved via THORChain, complicating recovery efforts. The initiative aims to prevent further spread of bad debt and restore confidence in decentralized finance platforms.
