BitGo has selected Chainlink as its exclusive partner for cross-chain infrastructure, moving $7.4 billion in WBTC and enhancing security measures.
BitGo, a leading cryptocurrency custodian, has announced its decision to partner with Chainlink for cross-chain infrastructure for its Wrapped Bitcoin (WBTC), marking a significant departure from its previous use of LayerZero.
Security comes first. Always has.

All future assets issued by BitGo will automatically be supported by Chainlink's Cross-Chain Interoperability Protocol (CCIP).
The new system will establish a single version of WBTC across various blockchains, eliminating the need for multiple derivative copies that were previously created. BitGo will maintain control over the token contracts, including transfer limits and parameters between networks.
“BitGo has long been built around a simple principle: security first,” stated CEO Mike Belshe.
BitGo's shift to Chainlink is driven by the latter's robust security framework, adherence to institutional standards, and its built-in control features. Transfers will be managed by at least 16 independent node operators to enhance security and reliability. Furthermore, the protocol allows issuers to specify transfer speed restrictions.
The timeline for fully implementing this transition across BitGo's supported networks with Chainlink remains undisclosed. However, Chainlink's catalog currently includes WBTC pools with CCIP support for both Ethereum and Ronin.
LayerZero Faces $15 Billion Exodus
The total value of assets that have transitioned from LayerZero to Chainlink, including WBTC, has surged to nearly $15 billion, a significant jump from approximately $7.2 billion before this announcement.
Other projects making similar transitions include Kraken with its kBTC token, the Bitcoin platform Solv Protocol, and additional entities such as Mantle, Lombard, Aave, and Kelp.
This trend follows a security breach involving the rsETH bridge in the LayerZero-based Kelp protocol, where hackers exploited vulnerabilities and stole $292 million due to reliance on a single-verifier security model. Consequently, LayerZero has since modified its security protocols.
It's important to note that while BitGo had integrated LayerZero in 2024 for transactions involving Avalanche and BNB Chain, it employed a dual verification system that helped ensure its transaction security.
The incident prompted LayerZero to reevaluate its security measures, acknowledging earlier mistakes in their single-verifier approach.
