KelpDAO Exploit Explained: How It Happened & How to Prevent It
Contents
The KelpDAO exploit is a major 2026 DeFi security incident involving a cross-chain bridge vulnerability that resulted in approximately $290–293 million in losses and widespread systemic impact across the DeFi ecosystem. The exploit involved rsETH bridging infrastructure and triggered cascading effects across lending platforms — most notably Aave, where the shock caused a $6.2 billion withdrawal panic and emergency suspension of rsETH markets. It is one of the largest DeFi exploits of 2026. Full technical details are still under investigation.
This page covers what the KelpDAO exploit was, how cross-chain DeFi attacks unfold, why every existing security layer failed, and what pre-transaction behavioral detection looks like in practice. Updated as new information becomes available.
