Solv Protocol’s Transition to Chainlink CCIP
In light of increasing concerns over cross-chain bridge security, Solv Protocol has announced a significant transition away from LayerZero. Following the recent exploit of Kelp DAO, which resulted in a staggering loss of $292 million, Solv is set to move its infrastructure for managing over $700 million in tokenized Bitcoin to Chainlink’s Cross-Chain Interoperability Protocol (CCIP).
Security Reassessment and Strategic Migration
The company’s decision, disclosed in a press release on Thursday, comes as part of a thorough security reassessment of cross-chain technologies. Solv Protocol will eliminate support for its bridging on LayerZero for various platforms, including Corn, Berachain, Rootstock, and TAC, in favor of adopting Chainlink’s CCIP as its standard framework.
Will Wang, Chief Technology Officer of Solv Protocol, emphasized that security is paramount in their operations: “Our transition to Chainlink CCIP showcases our unwavering commitment to security at the highest level. By ensuring that SolvBTC and xSolvBTC cross-chain transfers are fully secured with CCIP, we are providing users with confidence that our infrastructure offers robust, multi-layer defense against potential threats.”
He noted that this switch positions Solv to grow in a market that increasingly demands reliable and secure systems.
Background on Solv Protocol
Solv Protocol, which debuted in 2021 on the Ethereum blockchain, specializes in decentralized finance (DeFi) with its SolvBTC token that mirrors Bitcoin’s value. The platform enables users to deploy wrapped BTC and other Bitcoin derivatives across various blockchains for yield generation.
Concerns Over Cross-Chain Security
This migration follows alarming trends in cross-chain bridge incidents. Notably, the Kelp DAO breach, linked to LayerZero’s technology, highlights vulnerabilities in such infrastructures. Though Solv did not specifically address the Kelp incident, it acknowledged “recent hacks in the cross-chain ecosystem” as part of its motivation for seeking enhanced security measures.
“Through this strategic migration, we aim to minimize our risk exposure by discontinuing SolvBTC and xSolvBTC support for LayerZero in favor of Chainlink CCIP, which is recognized for being the most proven interoperability infrastructure available,” the protocol stated.
Cybersecurity Threats in Cross-Chain Bridges
Cross-chain bridges have become primary targets for cyberattacks, often due to their complex verification systems and significant amounts of locked assets. Previous high-profile breaches include the $622 million attack on Axie Infinity’s Ronin network bridge in 2022 and the $230 million hack of the Indian exchange WazirX in 2024; both were ultimately traced back to hacking groups believed to be linked with North Korea.
LayerZero attributed the Kelp DAO incident to the Lazarus Group of North Korea, highlighting that the project relied on a single-verifier setup contrary to best practices that advocate for multiple validators. Conversely, Kelp DAO contested this claim, accusing LayerZero of enabling the risky setup tied to the exploit. Kelp DAO has also decided to redesign its system, pivoting towards Chainlink CCIP, which employs multiple independent validators to assess transactions instead of relying on a single verifier.
Industry Response
Commenting on Solv’s transition, Chainlink Labs’ Chief Business Officer, Johann Eid, expressed pride in collaborating with Solv to enhance the secure transfer of their wrapped Bitcoin assets across different chains: “This migration exemplifies a broader trend within the DeFi sector, where leading protocols shift to Chainlink to uphold the highest security standards and facilitate the onboarding of the next billion users to blockchain technology.”
