The Kelp DAO hack could have been DeFi's 2026 black swan. 116k unbacked rsETH dumped into Aave caused a massive liquidity crunch, but an onchain recapitalization prevented collapse.
The Defi United coalition secured 137,215 ETH to plug the ~$290M hole with Arbitrum, Consensys, and Mantle carrying most of the load.
No forced liquidations. Just DAOs and founders coordinating to cover the bad debt. Crucially, zero user funds were lost, the only ones taking a haircut were the attackers themselves.
