Bitgo Shifts WBTC Infrastructure to Chainlink in Security Push

Crypto infrastructure firm Bitgo is replacing Layerzero with Chainlink as the exclusive cross-chain infrastructure provider for wrapped bitcoin (WBTC), marking a major change in how the $7.7 billion token will move across blockchain networks.

Moving assets between blockchains requires cross-chain infrastructure, sometimes called a bridge. These systems transfer tokens or messages from one blockchain to another, making them a critical part of the broader digital asset ecosystem. Because bridges have historically been frequent targets for hackers, security has become one of the industry’s highest priorities.

In the announcement, Bitgo said standardizing WBTC and future assets on Chainlink CCIP will give it a more consistent security model while allowing the company to manage transfers and operational policies through a single infrastructure platform.

Bitgo cited several factors behind its decision, including Chainlink’s security architecture, institutional compliance standards, and built-in risk controls.

According to the company, each CCIP bridge route is supported by at least 16 independent node operators spread across different organizations, geographic regions and hosting providers. That distribution is designed to reduce the likelihood that a single failure or coordinated attack could disrupt transfers.

The protocol also supports issuer-controlled transfer limits and configurable transaction controls. Bitgo said those features can function as automated safeguards by slowing or restricting transfers if suspicious activity is detected before a broader incident develops.

Bitgo also plans to use the Chainlink Cross-Chain Token standard to establish unified versions of WBTC across supported blockchains. Rather than maintaining separate implementations, the company said the approach provides a consistent and verifiable security model while preserving Bitgo’s ownership of its token deployments.

On Tuesday, Chainlink detailed that its infrastructure has supported more than $32 trillion in transaction value, secures more than $110 billion across cross-chain applications and DeFi, and powers roughly 70% of the global DeFi ecosystem. Bitgo’s migration adds one of the industry’s largest wrapped bitcoin products to that network.

The next milestone for users and institutions will be Bitgo’s rollout of WBTC onto Chainlink CCIP and the migration of future Bitgo-issued assets to the same cross-chain framework, providing a clearer picture of how quickly the company completes the transition away from its legacy infrastructure.
