Aave states the KelpDAO-related rsETH exploit could leave $123.7 million to $230.1 million in bad debt, with Mantle and Arbitrum facing different WETH shortfalls depending on how losses are accounted for.
Aave said the Kelp DAO cross-chain bridge exploit enabled about $190 million in undercollateralized borrowing after an attacker released 116,500 rsETH, deposited 89,600 rsETH into Aave, and borrowed ETH-related assets before the protocol froze the rsETH market. The protocol now states potential bad debt could total $123.7 million or $230.1 million, depending on how rsETH losses are accounted for. Under its Layer2-focused scenario, Mantle would face a 71.45% WETH shortfall and Arbitrum a 26.67% shortfall, while the final outcome depends on rsETH accounting treatment and LRTOracle exchange-rate updates. The incident had already triggered about $6 billion in TVL withdrawals. In related developments, a whale withdrew 98,032 wstETH and 3,000 cbBTC from Aave, worth about $494 million, and swapped 7,438 aEthWETH for 1,930 stETH and 5,272 ETH, taking a 237 ETH loss while still leaving 10,000 ETH on the protocol. Lido later said its EarnETH vault has roughly 9% exposure to rsETH, or about $21.6 million, following the April 18 bridge attack that stole around 116,500 rsETH worth $292 million.
