Svmuu reported that in April this year, KelpDAO's LayerZero bridge was exploited in a $292 million vulnerability attack, triggering an $8.45 billion deposit run on Aave within 48 hours, marking the largest capital outflow event in decentralized finance (DeFi) history. Aave founder Stani Kulechov stated that the design of Aave V3 withstood the market test, demonstrating the network's "resilience." However, independent data indicates that Aave's survival primarily relied on $300 million in emergency rescue, including a 25,000 ETH guarantee from the Aave DAO and a personal injection of 5,000 ETH (approximately $8.4 million) by Kulechov.
Kulechov attributed the vulnerability to third-party infrastructure rather than core smart contracts. However, analysts pointed out that this incident exposed deficiencies in Aave's risk architecture and insurance mechanisms, leading the platform to incur significant bad debt (approximately $123.7 million in wETH). To prevent future bridge failures from triggering systemic bank runs, Aave V4 will adopt a modular "hub-and-spoke" architecture, enabling local risk auto-adjustment and collateral freezing. (CoinDesk)
