Solv Protocol said it is migrating its entire tokenized bitcoin portfolio, including SolvBTC and xSolvBTC, from Layerzero to Chainlink’s Cross-Chain Interoperability Protocol (CCIP). The move covers roughly $700 million in assets and will affect bridge deployments on Corn, Berachain, Rootstock, and TAC networks, with Layerzero support being deprecated in phases.
Solv said it completed an “extensive security review” and is deprecating its Layerzero bridges. The team said SolvBTC and xSolvBTC are now “officially powered by Chainlink CCIP across all supported chains.”
Solv also said CCIP had already been part of its collateral verification stack, describing the migration as a consolidation rather than a full replacement.
Re (re.xyz), an onchain reinsurance protocol, also chose Chainlink CCIP as the exclusive cross-chain infrastructure for reUSD, its yield-bearing stablecoin. Re said reUSD has more than $160 million in market cap, and it reported protocol TVL above $475 million.
Re cited several CCIP features, including redundant validation by 16 or more independent node operators, native rate-limit circuit breakers, and SOC 2 Type 2 compliance.
Both decisions follow an April 18, 2026 exploit that drained approximately 116,500 rsETH, worth about $292 million at the time, from a Layerzero-powered bridge used by KelpDAO. KelpDAO said attackers used the stolen assets as collateral on Aave v3.
KelpDAO attributed the breach to a 1-of-1 verifier configuration within Layerzero’s infrastructure, which it described as creating a single point of failure. Layerzero disputed that framing, saying KelpDAO manually selected a non-recommended single-verifier model against Layerzero guidance and that it would no longer support such configurations.
The public dispute renewed scrutiny around how Layerzero’s Omnichain Fungible Token standard handles verifier setup and whether default configurations provide adequate protection.
Chainlink CCIP uses a different model, according to the article. Each bridge lane relies on multiple independent Decentralized Oracle Networks, with 16 or more security-reviewed node operators handling validation. The system uses separate codebases for execution and risk, and built-in rate limits are intended to act as circuit breakers if anomalous transfer volumes appear.
Huma Finance, a PayFi network, selected CCIP as the exclusive bridge for its PST yield product. Unlike Solv, Re, and KelpDAO, Huma was not migrating from an active Layerzero deployment, and its decision was described as forward-looking infrastructure selection following similar security reviews.
The combined scale of these shifts is described as nearly $1 billion when counting Solv and KelpDAO alone. The article says the moves have strengthened Chainlink’s position as a preferred cross-chain standard for protocols managing institutional-grade or high-value assets, with Chainlink executives characterizing the trend as a “flight to quality” toward infrastructure that includes default protections rather than configurations that place security responsibility on individual operators.
“Glad to see all the hard work that Chainlink has put into generating real security is being recognized as valuable by more and more teams in our industry,” Chainlink founder Sergey Nazarov remarked on X.
“It seems that focusing on making the secure and reliable solution is what wins in an industry where securing value is a key feature of everyone’s product.”
Nazarov added: “We have seen the trend of low quality data oracles with poor security being switched out for Chainlink for many years now, with that trend continuing on a regular basis.”
Holders of rsETH, SolvBTC, xSolvBTC, and reUSD are largely unaffected during the transition. Each protocol said it is structuring its migration in phases, with minimal required action from users in most cases.
Premium gym chains are entering a “golden era” that is ending or already in decline, as rising operating costs collide with shifting consumer preferences toward more flexible, community-based ways to exercise. Long-term memberships are shrinking, margins are pressured by higher rents and facility expenses, and competition from smaller, more personalized…
