BitGo is moving about $7.4 billion worth of Wrapped Bitcoin, WBTC, onto Chainlink’s Cross-Chain Interoperability Protocol, replacing LayerZero as its exclusive cross-chain provider. This isn’t a token upgrade, it’s a fundamental change to the plumbing that lets WBTC move between blockchains.

In wrapped assets like WBTC, trust comes from two places: custody of the underlying bitcoin and the system that transports the token representation across networks. In this case, BitGo is changing that transport layer for the largest wrapped bitcoin product in the market.

The timing also lands as bridge security faces sharper attention after the roughly $292 million Kelp DAO exploit, which intensified scrutiny of LayerZero-based setups. So this migration stands out not just for its size, but for what it says about how much weight the market now puts on cross-chain infrastructure and security design.

For users and counterparties, trust in WBTC’s movement across chains will now rest on Chainlink CCIP rather than LayerZero, alongside BitGo’s bitcoin custody.
