Kelp exploit highlights problem with non-isolated DeFi lending: Crypto execs
TL;DR
The Kelp liquid restaking protocol was exploited, resulting in a loss of approximately $293 million. Crypto executives warn that non-isolated lending in DeFi can lead to widespread ecosystem risks.

The exploit of the Kelp liquid restaking protocol shows how non-isolated lending and integrations in decentralized finance (DeFi) can cause broader ecosystem contagion, according to crypto industry executives and blockchain security firms.
Non-isolated lending on DeFi platforms, including earlier versions of the Aave lending protocol, exposes users to risks from all the various tokens used as collateral on the platforms, according to Michael Egorov, founder of the Curve Finance DeFi protocol.
Kelp was the target of a cyber attack on Saturday, causing the platform to pause smart contracts for its restaking token (rsETH) while it moved to investigate the attack that left the platform drained of about $293 million.
DeFi teams should also vet prospective digital assets to ensure that tokens do not feature single points of failure or attack surfaces before approving tokens as lending collateral on their platforms, Egorov said in an email.

He also warned against using cross-chain bridging architecture to transfer assets from one blockchain protocol to another, which was the root cause of this weekend’s Kelp exploit.
“Cross-chain is hard and potentially risky. Only use cross-chain infrastructure when absolutely necessary, and do it really carefully,” Egorov said.
He said the incident is a learning experience for DeFi, which the sector can use to grow and implement better cybersecurity protections as losses from crypto hacks, code exploits and scams reached $482 million in Q1 2026.

Q&A
What happened to the Kelp liquid restaking protocol?
The Kelp protocol was targeted in a cyber attack that drained about $293 million, prompting the platform to pause its smart contracts.
How does non-isolated lending affect DeFi platforms?
Non-isolated lending exposes users to risks from various collateral tokens, potentially leading to broader contagion in the DeFi ecosystem.
What should DeFi teams do to prevent exploits like the Kelp attack?
DeFi teams should vet digital assets to avoid single points of failure or attack surfaces before approving them as collateral.
