Solv Protocol is migrating over $700 million in tokenized Bitcoin infrastructure from LayerZero to Chainlink's Cross-Chain Interoperability Protocol (CCIP). The move follows the $292 million KelpDAO exploit, which was tied to LayerZero-powered bridge infrastructure and attributed to North Korea's Lazarus Group. Solv stated that the migration is part of a broader security review after recent cross-chain hacks, and it is deprecating LayerZero bridge support for Corn, Berachain, Rootstock, and TAC. Cross-chain bridges have become frequent targets for attackers due to their complex verification systems and large pools of locked funds. Past major bridge exploits include the $622 million Ronin Network hack and the $230 million WazirX hack, both linked to North Korean state-sponsored groups. Solv's chief technology officer emphasized that migrating to CCIP provides users with defense-in-depth security and institutional-grade assurance. For wallet and key holders, this migration underscores the importance of using protocols with robust multi-verifier security. Solv's shift to Chainlink CCIP, which uses multiple independent validators instead of a single verifier, aims to reduce the risk of exploits. Users of SolvBTC and xSolvBTC should be aware of the bridge deprecation and ensure they understand the new infrastructure to avoid potential disruptions.
