An attacker exploited Kelp DAO's LayerZero-powered bridge with a phantom message, minting $291M in rsETH on Ethereum without burning the corresponding tokens on Unichain. The stolen collateral was looped through Aave to borrow real assets, pushing WETH pools to 100% utilization, freezing user withdrawals, and triggering $6.2B in net Aave outflows by Sunday morning. Aave froze rsETH markets while Kelp paused contracts across mainnet and several L2s. AAVE dropped 16% to $90.13 and ETH slid 2% to $2,300 on the news.
