BitGo has migrated $7.4 billion in Wrapped Bitcoin from LayerZero to Chainlink's Cross-Chain Interoperability Protocol, bringing total assets moving away from LayerZero to nearly $15 billion. The migration reflects growing institutional preference for Chainlink's oracle-backed bridge architecture over LayerZero's messaging-layer approach, driven by security and counterparty risk concerns following scrutiny of cross-chain bridge vulnerabilities.
For Armada's crypto repo desk, WBTC is a potential collateral form for BTC-exposed counterparties such as market makers and miners who hold wrapped positions. A change in the underlying bridge protocol introduces new smart contract and settlement dependencies. Armada must verify that Fireblocks custody policies and SOC 2 attestations cover WBTC under the new Chainlink CCIP architecture before accepting it as eligible collateral.
