BitGo Moves $7.4B WBTC to Chainlink CCIP as Security Drives Infrastructure Shift

• BitGo adopted Chainlink CCIP for Wrapped Bitcoin, replacing LayerZero while making security its interoperability standard for future assets exclusively forward.
• KelpDAO exploit exposed verification weaknesses, prompting LayerZero to strengthen configurations while Chainlink emphasized certified safeguards and transfer controls.
• WBTC remains the largest wrapped Bitcoin token despite custody controversy, while BitGo retains ownership of token contracts amid growing institutional adoption.

 

BitGo has adopted Chainlink’s Cross-Chain Interoperability Protocol (CCIP) as the new cross-chain standard for Wrapped Bitcoin (WBTC), making the $7.4 billion token the largest asset to migrate from LayerZero. The decision also establishes CCIP as the interoperability solution for all future BitGo-issued assets.

According to BitGo, the migration reflects its long-standing emphasis on security as institutional clients demand stronger safeguards for assets moving across multiple blockchain networks.  BitGo CEO Mike Belshe explained that security remains the firm’s guiding principle, adding that Chainlink CCIP provides the controls, reliability, and risk management expected by institutional customers.

Moreover, the company confirmed that every future BitGo-issued asset will launch with CCIP instead of LayerZero’s Omnichain Fungible Token standard, where WBTC previously operated as the largest asset.

Several blockchain projects, including Kraken’s kBTC and Solv Protocol’s SolvBTC and xSolvBTC, have already selected Chainlink CCIP for interoperability, making WBTC the largest wrapped Bitcoin to join that migration.

Security concerns accelerate migration toward Chainlink CCIP

The latest migration follows increased scrutiny of bridge security after the $292 million KelpDAO exploit exposed weaknesses in cross-chain infrastructure. Attackers targeted the rsETH bridge by compromising off-chain systems supporting LayerZero’s verification process.

At the time of the exploit, the affected bridge relied on a single Decentralized Verifier Network configuration, allowing attackers to forge cross-chain messages after gaining control of the supporting infrastructure. LayerZero later updated its security framework to eliminate similar configurations, while Dune Analytics data showed that nearly half of LayerZero OApp contracts previously relied on the same 1-of-1 verification model.

Meanwhile, Chainlink highlighted several protections built into CCIP, including independent node operators, configurable transfer controls, transaction rate limits, and automated safeguards designed to reduce operational risks.

Furthermore, BitGo noted that CCIP remains the only cross-chain protocol holding both SOC 2 Type 2 and ISO 27001 compliance certifications, strengthening its appeal among institutions seeking regulated blockchain infrastructure.

Wrapped Bitcoin retains market leadership despite custody debate

WBTC remains the largest wrapped Bitcoin token, representing roughly 45% of the sector’s total market capitalization. Coinbase’s cbBTC follows with an estimated $6 billion market value, while competing wrapped Bitcoin products remain considerably smaller.

BitGo’s custody structure attracted criticism after partnering with Justin Sun-linked BiT Global during 2024. Under that arrangement, BiT Global received two of the three multisignature keys securing WBTC’s Bitcoin reserves.

Coinbase later removed WBTC from its platform and introduced cbBTC as an alternative. BiT Global challenged that decision in court before withdrawing the lawsuit following a federal ruling supporting Coinbase’s right to delist the token.

Despite the controversy, BitGo emphasized that it retains full ownership and control of WBTC’s token contracts. The company also noted that WBTC’s circulating supply has remained relatively stable despite the decline in Bitcoin’s market price.

Conclusion

BitGo’s decision places the largest wrapped Bitcoin token within Chainlink’s interoperability network while reinforcing the industry’s stronger emphasis on cross-chain security. The migration also highlights how infrastructure providers are prioritizing risk management as institutions evaluate blockchain connectivity solutions.
