Overview
- BitGo announced on Tuesday that it will use Chainlink’s Cross‑Chain Interoperability Protocol (CCIP) and the Cross‑Chain Token (CCT) standard as the exclusive cross‑chain infrastructure for WBTC, the largest wrapped‑Bitcoin product.
- The move covers roughly $7.3 billion in WBTC and pushes the total value of publicly announced migrations from LayerZero to Chainlink to about $14.5–$14.6 billion.
- BitGo said it will keep issuer control over token contracts, transfer rate limits and other operational settings under the CCT standard rather than handing those controls to an external bridge operator.
- The migration wave accelerated after a $292 million exploit of a LayerZero‑powered bridge earlier this year, prompting multiple projects to reconfigure cross‑chain setups and select CCIP for messaging and transfers.
- No detailed rollout schedule was disclosed, which leaves timing and transition risk open and concentrates systemic DeFi liquidity flows on a single interoperability protocol that market participants will now watch closely.
