Solv Moves $700 Million Bitcoin Infrastructure to Chainlink CCIP

• Solv Protocol will migrate the wrapped BTC infrastructure from LayerZero to Chainlink CCIP.
• The move followed the $292M Kelp DAO exploit tied to LayerZero-powered bridge systems.
• Solv will phase out LayerZero bridge support for Corn, Berachain, Rootstock, and TAC.

​​​​Solv Protocol is moving more than $700 million in tokenized Bitcoin infrastructure away from LayerZero after recent bridge exploits increased pressure on cross-chain security systems.

​​​​The protocol confirmed that Chainlink’s Cross-Chain Interoperability Protocol (CCIP) will become the default cross-chain layer for SolvBTC and xSolvBTC transfers across supported networks.

​​​​As part of the migration, Solv will remove LayerZero bridge support for Corn, Berachain, Rootstock, and TAC. The company said the move followed a full review of bridge security standards after multiple recent cross-chain attacks.

​​​​Solv Protocol runs Bitcoin-focused DeFi products built around SolvBTC, a wrapped Bitcoin asset that lets users move BTC liquidity across different blockchains while earning yield.

​​​​Chief Technology Officer Will Wang said the migration was built around lowering bridge risk and improving security guarantees for users moving assets between chains.

​​​​The company described Chainlink’s CCIP as a more battle-tested infrastructure layer with stronger defense systems and institutional-grade protection.

Kelp DAO Exploit Increased Pressure on LayerZero

​​​​The migration came weeks after attackers drained roughly $292 million from infrastructure connected to Kelp DAO, which relied on LayerZero bridge technology.

​​​​Kelp DAO later confirmed plans to move its rsETH bridge systems toward Chainlink CCIP as well.

​​​​The April exploit became one of the largest bridge-related attacks of the year. Reports later showed that attackers moved stolen rsETH into Aave v3 as collateral before some funds became frozen.

​​​​LayerZero blamed the attack on North Korea’s Lazarus Group and argued that Kelp DAO used a risky single-verifier setup instead of the recommended multi-validator protection.

​​​​Kelp DAO rejected that explanation and accused LayerZero of previously approving the same verifier structure before the exploit happened.

​​​​The dispute remains unresolved. LayerZero CEO Bryan Pellegrino said Kelp moved away from safer default settings, while Kelp claimed many LayerZero applications operated with similar one-verifier systems.

​​​​Security researchers later added more pressure to the debate. OpenZeppelin said there was no public proof showing a direct smart contract failure in the Kelp DAO exploit. Instead, the company said the issue appeared tied to bridge operations, integration systems, and message verification infrastructure.

​​​​It is important to note that Solv did not directly blame LayerZero in its migration announcement. The company instead pointed to “recent cross-chain hacks” and broader security reviews across the industry.

Chainlink Gains More Ground in Cross-Chain Infrastructure

​​​​Chainlink Labs said Solv’s migration reflects a wider trend inside decentralized finance, where protocols are choosing infrastructure providers with stronger security guarantees.

​​​​Chief Business Officer Johann Eid said Chainlink CCIP now plays an increasingly important role in securing large cross-chain asset transfers. 

​​​​The migration also increases Chainlink’s position inside Bitcoin-based DeFi markets, where wrapped BTC systems depend heavily on secure communication between multiple blockchains.
