Solv Protocol is migrating more than $700 million in tokenized bitcoin assets from LayerZero to Chainlink’s Cross-Chain Interoperability Protocol (CCIP), marking one of the largest single shifts in cross-chain bridge infrastructure. The migration covers SolvBTC and xSolvBTC, Solv’s wrapped bitcoin products used across DeFi and BTCfi markets, and will deprecate LayerZero bridge support on the Corn, Berachain, Rootstock, and TAC networks.
The decision, first reported by CoinDesk, follows an internal security review prompted by a series of high-profile cross-chain exploits. Solv’s engineering team concluded that Chainlink’s decentralized oracle network and risk management layers provide a stronger architecture against bridge-level attacks. The move comes shortly after Kelp DAO’s shift from LayerZero to Chainlink following an April exploit that drained 116,500 rsETH (approximately $292 million) from a LayerZero-powered bridge.
Kelp and LayerZero traded blame over the exploit: LayerZero said Kelp used a single-verifier configuration contrary to recommendations, while Kelp claimed LayerZero personnel reviewed and approved the setup. The dispute has elevated verifier design to a critical security issue for high-value cross-chain assets. LayerZero later announced it would no longer sign messages for applications using a 1-of-1 model.
Johann Eid, Chief Business Officer at Chainlink, told CoinDesk: “We are speaking to many teams across the industry and there is a clear and accelerating trend where protocols like Solv are migrating to Chainlink in a flight to quality reminiscent of the rapid shifts during DeFi summer.” He added that by choosing CCIP, Solv gains cross-chain infrastructure that is “secure and decentralized by default.”
Together, Kelp and Solv represent over $2 billion in protocol asset value moving to Chainlink’s infrastructure. Solv had already collaborated with Chainlink on real-time collateral verification for SolvBTC pricing. The phased migration is designed to minimize user disruption, and the protocol will provide guidance for any required actions. The move may prompt other protocols managing large tokenized asset pools to reevaluate their bridge dependencies, potentially accelerating CCIP adoption as the standard for secure high-value transfers.
