Kelp rsETH bridge exploit triggers mass Aave withdrawals — >$5.4B ETH pulled; ~$293M exploit

On April 18, 2026 an attacker exploited a minting flaw in KelpDAO’s rsETH to create uncollateralized rsETH, deposited the inflated tokens into Aave V3 on Ethereum and Arbitrum, and generated bad debt. On-chain investigator ZachXBT flagged six attacker wallets (pre-funded via Tornado Cash) and estimated losses of $280M+ (community estimates $100M–$293M). The exploit pushed AAVE down ~10–13% while KelpDAO had not confirmed the event and analysts continue tracing funds and monitoring attacker wallets.
