Headline: Solv relocates $700M+ in tokenized BTC to Chainlink’s CCIP, dropping LayerZero amid cross‑chain security concerns
Solv Protocol announced it is migrating more than $700 million worth of its tokenized Bitcoin — SolvBTC and xSolvBTC — to Chainlink’s Cross‑Chain Interoperability Protocol (CCIP), and will deprecate LayerZero bridge support across Corn, Berachain, Rootstock and TAC. The assets being moved are Solv’s wrapped Bitcoin products used across DeFi and BTC‑fi markets.
Why the switch? Solv said an updated security review and a string of recent cross‑chain hacks prompted the decision, with CCIP chosen as the protocol’s standard bridge infrastructure. Chainlink’s CCIP is a cross‑chain messaging and transfer network that lets blockchains send tokens, messages and data securely between one another.
The move follows Kelp DAO’s similar pivot after an April exploit drained 116,500 rsETH (about $292 million) from a LayerZero‑powered bridge. Kelp and LayerZero have publicly traded blame over the incident: LayerZero says Kelp used a single‑verifier (1‑of‑1) configuration against its recommendation to adopt a multi‑verifier design, while Kelp says LayerZero reviewed and approved the setup it later faulted. The dispute has elevated verifier architecture into a live security debate for high‑value cross‑chain assets; LayerZero has since said it will no longer sign messages for applications using a 1‑of‑1 model.
Solv’s migration hands Chainlink a second notable post‑hack win in the cross‑chain space: alongside Kelp’s move of liquid restaked ETH, the two projects together represent more than $2 billion in protocol assets shifting toward Chainlink’s infrastructure.
“We are speaking to many teams across the industry and there is a clear and accelerating trend where protocols like Solv are migrating to Chainlink in a flight to quality reminiscent of the rapid shifts during DeFi summer,” Johann Eid, Chainlink’s chief business officer, told CoinDesk. “The industry’s largest protocols are realizing they can no longer rely on cross‑chain and oracle infrastructure that push liability onto users and blame them for systemic failures. By choosing CCIP, Solv gets cross‑chain infrastructure that is secure and decentralized by default.”
Solv had already been working with Chainlink for real‑time collateral verification used in SolvBTC pricing, smoothing the transition onto CCIP. The move underscores how recent bridge failures are reshaping where large protocols choose to custody and move assets across chains.
