BitGo, a cryptocurrency custodian, has chosen Chainlink as its exclusive provider for cross-chain infrastructure for Wrapped Bitcoin (WBTC), moving away from LayerZero.
Security comes first. Always has.

All future assets from the firm will also automatically receive CCIP support.
Under the Chainlink Cross-Chain Token standard, there will be a single BitGo version of WBTC on each blockchain, replacing the derivative copies previously created by the bridge. The company retains control over token contracts, transfer limits, and inter-network parameters.
“BitGo has long been built around a simple principle: security first,” said CEO Mike Belshe.
The company cited the protocol's security architecture, compliance with institutional standards, and built-in control mechanisms as reasons for the transition. Each transfer direction is serviced by at least 16 independent node operators, distributed across different organizations, regions, and hosting providers. Additionally, the protocol allows the issuer to set transfer speed limits.
Details regarding the completion timeline for the transition across all supported networks of BitGo and Chainlink have not been disclosed. The Chainlink catalog already lists WBTC pools with CCIP support for Ethereum and Ronin.
Outflow from LayerZero Nears $15 Billion
Including WBTC, the total value of assets whose issuers have announced a transition from LayerZero to Chainlink has reached nearly $15 billion, up from approximately $7.2 billion prior to this announcement.
Similar decisions have been made by Kraken for its kBTC token, the Bitcoin platform Solv Protocol, as well as Mantle, Lombard, Aave, and Kelp.
The impetus for these moves was the hacking of the rsETH bridge on the LayerZero-based Kelp protocol. The platform used a single verifier (1/1 DVN), which was LayerZero Labs itself. Hackers compromised external RPC servers, submitted fake data, and stole $292 million.
In response, LayerZero revamped its security and abandoned the single-verifier scheme.
However, this incident did not impact the WBTC bridge: BitGo integrated LayerZero in 2024 for operations with Avalanche and BNB Chain, but each transaction required dual verification—one from BitGo's validator and one from either LayerZero or Polyhedra.
It is worth noting that in May, the project team acknowledged that using a single-verifier configuration to secure large transactions was a mistake.
