Solv Protocol, a DeFi platform focused on Bitcoin-based assets, has announced a full migration to the Chainlink Cross-Chain Interoperability Protocol (CCIP) as part of an upgraded security strategy for cross-chain transfers. The migration will encompass more than $700 million in Bitcoin-related assets across SolvBTC and xSolvBTC.
Solv Ends LayerZero Bridging Support
As part of the transition, Solv announced it will discontinue LayerZero bridging support for SolvBTC and xSolvBTC on Corn, Berachain, Rootstock, and TAC. The platform said this move is intended to reduce risk exposure tied to its existing bridging stack and to standardize its cross-chain infrastructure on Chainlink CCIP.
Solv identified cross-chain bridges as among the highest-risk components of decentralized finance, noting that weaknesses in bridge infrastructure can introduce significant systemic risk across the sector. Before committing to Chainlink CCIP, the team completed a thorough review of available cross-chain interoperability solutions and selected CCIP based on security and operational considerations.
Johann Eid, Chief Business Officer at Chainlink Labs, commented on the migration:
“We are proud to work with the Solv team and support their migration to Chainlink CCIP as the standardized way that their wrapped Bitcoin assets are securely transferred cross-chain. Solv’s migration to CCIP reflects a broader shift across the DeFi industry of leading protocols adopting Chainlink to deliver the highest level of security required to bring the next billion users onchain.”
LayerZero Breach Fallout Deepens
Solv’s decision to switch its cross-chain infrastructure follows a major exploit on April 18 involving a LayerZero-powered protocol, KelpDAO, which resulted in roughly $292 million in reported losses. Public statements from KelpDAO alleged the attacker, reportedly linked to North Korea’s Lazarus Group, exploited vulnerabilities associated with LayerZero’s infrastructure.
KelpDAO disputed LayerZero Labs’ characterization that the breach was the result of a configuration error specific to KelpDAO. Instead, KelpDAO maintained its deployment followed LayerZero’s official documentation and reflected a standard implementation pattern used by many applications in the ecosystem.
KelpDAO further said that LayerZero’s DVN signed forged transactions worth more than $100 million before the protocol paused contracts to halt further loss. In its postmortem, LayerZero acknowledged that attackers had gained access to RPC endpoints connected to its DVN and compromised multiple nodes in what the team described as an RPC spoofing attack.
In the wake of the exploit, KelpDAO signaled plans to move away from LayerZero’s OFT standard and transition assets such as rsETH to Chainlink CCIP. That decision, and similar responses from other protocols, underscores a shifting sentiment in DeFi toward consolidating cross-chain activity under models they consider to offer stronger guarantees and reduced attack surface.
For Solv, the migration to Chainlink CCIP represents both a tactical reduction of immediate bridging risk and a strategic alignment with a widely adopted interoperability framework. By consolidating its wrapped Bitcoin assets onto CCIP, Solv aims to provide more robust safeguards for users and counterparties while maintaining cross-chain functionality across multiple networks.
The move also reflects broader industry pressure to reassess cross-chain trust assumptions and operational practices after high-profile exploits. Protocols and infrastructure providers are increasingly prioritizing formal security reviews, redundancy, and clearer operational models to mitigate the complex failure modes that arise when assets move between chains.
Solv’s change will affect users and partners that rely on SolvBTC and xSolvBTC across the listed networks. The protocol has indicated it will coordinate migration steps and communications to minimize disruption, while continuing to evaluate cross-chain tools and processes that balance interoperability with security.
As the DeFi ecosystem adapts, migrations like Solv’s highlight the trade-offs teams face: preserving cross-chain liquidity and user experience while reducing dependence on components perceived as higher risk. Industry observers will likely watch Solv’s implementation of Chainlink CCIP closely, assessing its operational performance and whether similar migrations accelerate among other protocols handling large volumes of wrapped assets.
