BitGo Selects Chainlink CCIP for WBTC Migration
BitGo is migrating Wrapped Bitcoin to Chainlink CCIP and will use the protocol exclusively for all future BitGo-issued digital assets.
BitGo is overhauling the cross-chain infrastructure behind Wrapped Bitcoin (WBTC), selecting Chainlink’s Cross-Chain Interoperability Protocol (CCIP) as its exclusive interoperability solution. The move replaces the token’s previous reliance on LayerZero’s OFT standard and reflects a growing industry focus on stronger security models following several high-profile bridge exploits.
With a market capitalization of approximately $7.4 billion, WBTC remains the largest wrapped Bitcoin token and one of the most widely used assets across decentralized finance (DeFi). BitGo said the transition will also establish Chainlink CCIP as the default cross-chain standard for all future BitGo-issued assets, extending the decision beyond WBTC alone.
BitGo Prioritizes Security in Cross-Chain Infrastructure
The announcement comes as crypto infrastructure providers place greater emphasis on institutional-grade security and risk management for cross-chain asset transfers.
BitGo CEO and co-founder Mike Belshe said the company selected Chainlink because its architecture aligns with the firm’s long-standing security priorities.
“BitGo has long been built around a simple principle: security comes first. As we expand support for BitGo-issued assets across more chains, Chainlink CCIP gives us a proven, institutionally adopted interoperability standard that aligns with the controls, reliability, and risk management our clients expect from BitGo.”
The company confirmed that all future BitGo-issued digital assets will rely exclusively on Chainlink CCIP for interoperability, marking a significant endorsement of the protocol within institutional crypto infrastructure.
The decision also continues a broader migration trend across the industry. In recent months, several projects have adopted Chainlink CCIP, including Kraken’s kBTC, as well as Solv Protocol’s SolvBTC and xSolvBTC.
Why the Migration Matters
The transition is significant because WBTC accounts for roughly 45% of the entire wrapped Bitcoin market, making it the largest asset to move away from LayerZero’s OFT framework.
While Coinbase’s cbBTC has grown into the second-largest wrapped Bitcoin with a market capitalization of around $6 billion, other competing wrapped Bitcoin assets remain substantially smaller, with the next-largest valued below $500 million.
For the broader ecosystem, the migration highlights three major trends:
- Higher security expectations for cross-chain protocols following recent bridge exploits.
- Growing standardization around a smaller number of interoperability solutions.
- Increasing institutional demand for audited, compliance-focused infrastructure.
As more regulated custodians expand support across multiple blockchains, interoperability standards are becoming a critical component of digital asset infrastructure rather than simply a technical feature.
Security Models Under Increasing Scrutiny
The decision follows heightened attention on bridge security after the $292 million KelpDAO exploit earlier this year.
The incident targeted rsETH’s LayerZero bridge, which had been configured with a 1-of-1 Decentralized Verifier Network (DVN). Because only a single verifier operated by LayerZero Labs was responsible for validating cross-chain messages, attackers were able to compromise the off-chain RPC infrastructure supplying data to that verifier and forge a fraudulent message that enabled the theft.
Following the exploit, LayerZero updated its security model to prevent similar configurations from being used in the future.
Chainlink CCIP takes a different approach. According to Chainlink, each CCIP bridge is secured by a minimum of 16 independent, security-reviewed node operators, providing multiple layers of validation instead of relying on a single verifier.
The protocol also includes rate limits, configurable transfer controls, and, according to the announcement, is the only cross-chain protocol holding both SOC 2 Type 2 and ISO 27001 compliance certifications.
WBTC Continues to Evolve
Launched in 2019, WBTC pioneered the concept of bringing Bitcoin liquidity into Ethereum-based DeFi and once represented virtually the entire wrapped Bitcoin market, with more than $15 billion in circulation at its peak.
The token later faced increased scrutiny after BitGo partnered with BiT Global, a custody firm linked to Justin Sun, under a multi-jurisdictional custody arrangement introduced in 2024. Under that structure, BiT Global received two of the three multisignature keys controlling WBTC’s Bitcoin reserves.
The arrangement prompted Coinbase to delist WBTC, citing its listing standards, before introducing its own wrapped Bitcoin product, cbBTC. BiT Global subsequently filed an antitrust lawsuit against Coinbase but later withdrew the case after a federal judge ruled that the exchange had the right to remove the asset from its platform.
Despite those developments, BitGo continues to retain full ownership and control of WBTC’s token contracts, while the token’s circulating supply has remained relatively stable even as its market value declined alongside Bitcoin’s price since late 2025.
As institutional participation in digital assets continues to expand, security, compliance, and interoperability are increasingly becoming competitive differentiators. BitGo’s decision to standardize on Chainlink CCIP suggests that large custodians are prioritizing resilient cross-chain infrastructure over flexible but more configurable models, potentially accelerating broader adoption of standardized interoperability solutions across the crypto ecosystem.
