Evercrest Technologies, the company behind liquid restaking protocol KelpDAO, has filed a notice of civil claim in the Supreme Court of British Columbia against LayerZero Labs Ltd., LayerZero Labs Canada Inc. and co-founder Bryan Pellegrino over the April 18 exploit of Kelp's rsETH bridge. The claim alleges negligent misrepresentation, negligence and defamation, and seeks compensatory, aggravated and punitive damages. Evercrest says LayerZero reviewed and endorsed the bridge's 1-of-1 decentralized verifier network, or DVN, configuration, told it there was no problem with the default setup and directed it to use the same configuration as another bridge. It alleges LayerZero did not warn Kelp about the risks of relying on a single DVN, despite warning USDT0 about default configurations. The exploit released 116,500 unbacked rsETH worth about $292 million at the time and occurred at about 17:35 UTC, according to the claim. Evercrest alleges social engineering led to malware being installed on a LayerZero developer's computer, compromising the security infrastructure. LayerZero has attributed the incident to Kelp's single-DVN setup and, in its post-incident account, said attackers linked to North Korea's Lazarus Group poisoned RPC infrastructure and caused a verifier to approve a forged cross-chain message. Pellegrino has called the claim meritless. Kelp says users withdrew more than $650 million after the exploit, its sbUSD product was later sunset, and it is migrating rsETH to Chainlink's Cross-Chain Interoperability Protocol. No court has ruled on the allegations.
