Solv Protocol Ditches LayerZero for Chainlink, Moving $700M in Tokenized Bitcoin
Solv Protocol announced on May 7, 2026 that it is migrating approximately $700 million in tokenized bitcoin infrastructure from LayerZero to Chainlink's Cross-Chain Interoperability Protocol (CCIP), citing a security review and the $292 million Kelp DAO bridge exploit that rattled DeFi markets in April.
The migration covers SolvBTC and xSolvBTC, the protocol's bitcoin-pegged liquid staking tokens. These tokens allow holders to earn yield on their bitcoin across multiple blockchains without selling the underlying asset. Solv will deprecate LayerZero support on four networks: Corn, Berachain, Rootstock, and TAC. Kelp DAO also migrated to Chainlink CCIP following the April exploit; the two protocols together have shifted nearly $1 billion in assets away from LayerZero within weeks of each other.
The Hack That Triggered the Shift
On April 18, 2026, Kelp DAO was drained of approximately $292 million worth of rsETH (a liquid restaking token), representing roughly 18% of the token's total circulating supply, making it the largest DeFi exploit of the year so far. According to post-mortems from Halborn Security and Chainalysis, attackers attributed to North Korea's Lazarus Group compromised two RPC nodes feeding data to LayerZero's transaction verifier, then launched a distributed denial-of-service attack on backup nodes to isolate the compromised sources. With no clean data left, the attackers injected a fabricated cross-chain message and the bridge released the funds. Kelp's emergency multisig froze contracts 46 minutes after the drain.
A public dispute followed over who bore responsibility. LayerZero argued that Kelp had used a 1-of-1 DVN (Decentralized Verifier Network) configuration, meaning only a single validator was required to approve cross-chain messages, against LayerZero's own recommendations for multi-validator redundancy. Kelp countered that LayerZero's quickstart guide, default GitHub templates, and onboarding documentation all pointed to that same single-validator setup, and that a LayerZero team member had explicitly told Kelp there was "no problem on using defaults either."
Kelp also argued the configuration is not unusual: roughly 40% of protocols currently deployed on LayerZero use the same single-DVN arrangement.
Chainlink community manager Zach Rynes accused LayerZero of "deflecting responsibility" and "throwing Kelp under the bus for trusting a setup LayerZero itself supported."
Why Solv Moved and Where It Landed
Solv Protocol manages over $2.8 billion in total value locked. SolvBTC alone accounts for more than $1.9 billion of that, backed by over 28,000 BTC deposited by more than 537,000 users globally. Cross-chain messaging is core to the protocol's operation: SolvBTC must move between networks like Ethereum, BNB Chain, Arbitrum, and others for the product to function. Solv had already integrated Chainlink for real-time collateral verification and SolvBTC pricing before this announcement; this migration extends that relationship to cover the bridge layer itself.
The decision also follows a separate security incident at Solv earlier in 2026, when an exploit drained approximately $2.7 million from a Bitcoin yield vault. That breach made the team especially attentive to re-evaluating bridge infrastructure across the protocol.
"Security is the foundation of everything we build at Solv, and our migration to Chainlink CCIP reinforces that commitment at the highest level," said Will Wang, Solv's CTO.
Chainlink CCIP uses a dual DON (Decentralized Oracle Network) architecture, where multiple independent oracle networks each validate cross-chain messages. A separate Risk Management Network monitors activity and can pause transfers if anomalies are detected. The protocol also enforces a timelock on infrastructure upgrades, requiring a review window during which node operators can veto changes. Chainlink holds SOC 2 Type 1, SOC 2 Type 2, and ISO/IEC 27001:2022 certifications audited by Deloitte & Touche LLP. The protocol's infrastructure has facilitated more than $18 trillion in on-chain transaction value.
Johann Eid, Chief Business Officer at Chainlink Labs, called the Solv migration part of "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" (the mid-2020 period of rapid DeFi protocol adoption and liquidity growth).
Implications for Emerging Markets
For users in South Asia and Africa, where BTCfi adoption is growing alongside record-high overall crypto engagement, this migration has direct implications. India ranks first globally in the 2026 Chainalysis Global Crypto Adoption Index; Nigeria ranks second; Pakistan ranks eighth; Ethiopia and Kenya both entered the top 15 this year.
Users in these markets likely include holders of wrapped bitcoin products such as SolvBTC, given that the protocol counts more than 537,000 global users and that countries including India and Pakistan have large populations of BTC holders increasingly exploring DeFi yield strategies. Country-level user data for Solv is not publicly available, but that broader regional context suggests meaningful exposure. Cross-chain transfers of SolvBTC will now route through Chainlink CCIP, changing the underlying security model for those transactions.
Rootstock (RSK) is notable among the four chains losing LayerZero support. RSK is a Bitcoin sidechain widely used in Latin America and by Bitcoin-native communities across sub-Saharan Africa. Users and developers on Rootstock should monitor Solv's documentation for timeline details on bridge continuity under CCIP.
For Web3 developers in Lagos, Nairobi, Bangalore, or Karachi building applications on top of SolvBTC, the practical requirement is a contract-level migration: any application using LayerZero's OFT (Omnichain Fungible Token) standard to move SolvBTC will need to update to CCIP-compatible interfaces. As of publication, Solv has not yet published a firm deprecation timeline for the four affected chains.
What Comes Next
Industry observers note that the combined weight of Kelp and Solv leaving LayerZero, representing roughly $1 billion in assets, signals sustained pressure on LayerZero to address its default configuration practices publicly and substantively.
The $13 billion in TVL that exited DeFi platforms in the two days following the Kelp hack underscores how quickly user confidence moves when a major bridge fails. Whether other protocols currently using single-DVN configurations follow Solv's lead will be one of the more consequential infrastructure storylines in DeFi for the remainder of 2026.
