KelpDAO Hack Fallout Pushes Another DeFi Protocol Toward Chainlink CCIP Migration

Bitcoin-focused DeFi platform Solv Protocol announced that it is fully migrating to the Chainlink Cross-Chain Interoperability Protocol (CCIP) as part of its updated security strategy for cross-chain transactions.

The move will cover more than $700 million in Bitcoin-related assets across SolvBTC and xSolvBTC.

Solv Ends LayerZero Bridging Support

As part of the transition, Solv said it will discontinue LayerZero bridging support for SolvBTC and xSolvBTC on Corn, Berachain, Rootstock, and TAC. The platform explained that it is reducing risk exposure on its existing bridging stack and standardizing its infrastructure on Chainlink CCIP.

Solv described cross-chain bridges as one of the highest-risk areas in decentralized finance, while noting that vulnerabilities in bridge infrastructure can create significant systemic risks for the sector. The platform also confirmed carrying out a complete updated review of available cross-chain interoperability solutions before selecting Chainlink CCIP.

Commenting on the development, Chainlink Labs’ Chief Business Officer, Johann Eid, said,

LayerZero Breach Fallout Deepens

Solv Protocol’s decision to migrate its cross-chain infrastructure to Chainlink comes weeks after the massive April 18 exploit involving LayerZero-powered KelpDAO, which resulted in losses of roughly $292 million. The attacker, reportedly linked to North Korea’s Lazarus Group, allegedly exploited weaknesses tied to LayerZero’s infrastructure, according to KelpDAO’s public statements.

The DeFi protocol pushed back against claims from LayerZero Labs that the breach stemmed from a configuration issue unique to KelpDAO. Instead, Kelp argued that the setup followed LayerZero’s official documentation and reflected a standard deployment model used by many applications across the ecosystem.

Kelp further claimed that LayerZero’s DVN signed forged transactions worth more than $100 million before the protocol paused its contracts and stopped additional losses. LayerZero later acknowledged in its postmortem that attackers gained access to RPC endpoints connected to its DVN and compromised multiple nodes during what it described as an RPC spoofing attack.

Following the exploit, KelpDAO announced plans to move away from LayerZero’s OFT standard and transition rsETH to Chainlink’s CCIP framework.
