Solv Protocol has said it is moving more than $700 million in tokenized bitcoin enable Chainlinks Cross-Chain Interoperability Protocol (CCIP) and deprecated LayerZero bridge support across Corn, Berachain, Rootstock and TAC.
The migration covers SolvBTC and xSolvBTC, Solv’s wrapped bitcoin assets used across DeFi and BTCfi markets. Solv said it made the decision following an updated security review and recent cross-chain hacks, pointing to CCIP as its default bridge infrastructure.
Chainlink’s CCIP is a bridge that connects blockchains, enabling the transfer of tokens, messages and data between different decentralized networks.
Solv’s move follows Kelp DAO’s switch from LayerZero to Chainlink after an exploit in April drained 116,500 rsETH, worth about $292 million, from its LayerZero-powered bridge.
Kelp and LayerZero have since swapped blame for the setup behind the exploit. LayerZero said Kelp used a single-verifier configuration despite recommendations to adopt a multi-DVN model, while Kelp says LayerZero staff reviewed and approved the configuration they later blamed for the attack.
The dispute has turned verifier design into a live security issue for valuable assets across chains, as Kelp says the 1-of-1 setup was not an advantageous case. LayerZero says it was an application-level configuration choice and has since said it will no longer sign messages for applications using this model.
Solv’s migration gives Chainlink another post-hack win in cross-chain infrastructure. Kelp moves liquid traded ETH to it, while Solv moves tokenized bitcoin.
Together, Kelp and Solv represent more than $2 billion in protocol asset value moving toward Chainlink’s cross-chain infrastructure.
“We speak 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,” Johann Eid, Chief Business Officer at Chainlink, told CoinDesk.
“The industry’s largest protocols are realizing that they can no longer rely on cross-chain and oracle infrastructure that push responsibility onto users and blame them for systemic failures,” Eid added. “By choosing CCIP, Solv gets cross-chain infrastructure that is “secure and decentralized by default.”
Solv had already worked with Chainlink to offer real-time security verification for SolvBTC prices.
