Solv Protocol is moving more than 700 million dollars in tokenized Bitcoin from LayerZero to Chainlink’s Cross‑Chain Interoperability Protocol (CCIP). The migration makes Chainlink Solv’s new standard bridge for its wrapped Bitcoin products.
Solv’s move comes after an internal security review and a wave of high‑profile cross‑chain bridge hacks. The team said recent incidents convinced them to upgrade the infrastructure used to move assets between blockchains.
The migration covers SolvBTC and xSolvBTC, which are Solv’s tokenized Bitcoin assets used across DeFi and BTCfi markets. These wrapped BTC tokens live on chains like Ethereum and other networks, are backed by bitcoin, and rely on bridges to move across ecosystems. Solv will now deprecate LayerZero support across Corn, Berachain, Rootstock, and TAC as it standardizes on Chainlink CCIP.
Solv says it chose CCIP for its security features, including Chainlink’s decentralized oracle network and additional risk‑management layers. These systems aim to reduce the chance that a single failure or misconfigured verifier can lead to a large exploit.
Link to KelpDAO Exploit and “Flight to Quality”
The decision follows Kelp DAO’s earlier move to drop LayerZero and migrate liquid-restaked ETH to Chainlink following an April exploit. That attack drained about 116,500 rsETH, worth roughly 292 million dollars, from a LayerZero‑powered bridge. Kelp and LayerZero have since argued over the bridge’s single‑verifier setup, which LayerZero now says it will no longer support.
Together, the migrations by Solv and Kelp shift close to 1 billion dollars in assets toward Chainlink CCIP. Chainlink’s chief business officer, Johann Eid, described the trend as a “flight to quality” in cross‑chain infrastructure. He argued that large protocols no longer want bridges that push liability onto users when things go wrong.
For Chainlink, Solv’s decision is a second major win after the Kelp switch. Kelp is moving liquid restaked ETH, while Solv is moving tokenized Bitcoin, giving CCIP a bigger role in both ETH and BTC‑based markets.
Solv has not given a precise end date for the migration, but it says the process will happen in phases. The team plans to keep existing positions accessible and issue clear instructions for any user actions, such as switching bridge routes or updating contracts. As a result, the protocol expects limited disruption for most holders of SolvBTC and xSolvBTC
