A substantial breach has occurred within Kelp DAO, a cross-chain decentralized finance (DeFi) hub, causing an immediate protocol suspension. The critical exploit resulted in the loss of approximately $292 million in rsETH assets and was linked to a flaw intertwined with LayerZero’s cross-chain mechanisms. This incident has led to a domino effect among platforms integrated with rsETH, prompting urgent crisis management responses.
What triggered Kelp DAO’s rapid response?
Kelp DAO, renowned for its facilitation of cross-chain transactions through rsETH, confirmed the attack at 17:35 UTC on a recent Saturday. Attackers strategically operated a call to LayerZero’s “lzReceive” function within the EndpointV2 contract, resulting in the illicit transfer of assets to various malicious accounts. The breach took advantage of LayerZero’s integrations, enriching the attackers under a veil of anonymity provided by Tornado Cash, a prominent privacy tool used hours before the attack.
Amid the breach, Kelp DAO’s emergency team enacted a complete shutdown of its protocol, including critical functions such as the rsETH token activities and related modules, to staunch further theft. Although attackers attempted further drains valued at $50 million each, timely intervention prevented additional losses, capping the total potential damage just under $400 million.
Earlier today we identified suspicious cross-chain activity involving rsETH. We have paused rsETH contracts across mainnet and several L2s while we investigate. We are working with LayerZero, Unichain, our auditors and top security experts…
As a protocol, Kelp DAO supports liquid restaking across more than 20 blockchain ecosystems including Arbitrum and Base. Kelp’s governance token, rsETH, comprises a significant portion of its total value locked, with high stakes now hanging in the balance following the breach.
How did Aave safeguard its platform?
The aftermath swiftly impacted other DeFi players, notably Aave, a decentralized lending protocol that responded by freezing all rsETH markets on their platforms to mitigate risk associated with tainted liquidity. This protective measure was catalyzed by a 10% dip in AAVE’s market price, showcasing investor concern over potential insolvencies.

Despite the anxiety, Aave assures that their smart contracts remain unimpaired, targeting rsETH’s compromised status as the root of concerns. Although initial dialogue considered leveraging Aave’s safety measures, decisions are postponed pending evaluations of the exploit’s ramifications.
The seized rsETH constitutes around 18% of its circulating supply, escalating fears among asset holders and protocols utilizing rsETH as a secure instrument.
– No additional thefts succeeded post initial halt, demonstrating effective system freeze.
– Rapid reaction by team mitigated extra $99 million in potential loss.
– Assurances of unbreached main protocol build user trust.
While trading for rsETH hovers near $2,500, volatility persists amid doubts about Kelp DAO’s viability. The organization, led by Amitej Gajjala, has yet to release comprehensive findings beyond technical probes and collaborations with key tech partners.
The scale and nature of the exploit reignites critical discussions regarding cross-chain bridge architectural vulnerabilities in DeFi ecosystems. Stakeholders are urged to reassess risk management strategies, as deeper forensic inquiries and asset recovery processes progress.
