BitGo announced on August 4 that it will replace LayerZero with Chainlink Cross-Chain Interoperability Protocol (CCIP) as the exclusive cross-chain provider for $7.3 billion of wrapped bitcoin (WBTC), pushing the total value of announced LayerZero-to-Chainlink migrations to nearly $15 billion.
The shift marks a major infrastructure realignment following the $292 million exploit of Kelp DAO’s LayerZero-powered bridge earlier in 2026, which intensified scrutiny of LayerZero bridge configurations. BitGo will standardize WBTC deployments using Chainlink’s Cross-Chain Token standard and deploy CCIP by default for future assets.
BitGo initially selected LayerZero in 2024 to expand WBTC across Avalanche and BNB Chain. That configuration required BitGo’s own verifier and either LayerZero or Polyhedra to approve each cross-chain transfer. The new Chainlink arrangement consolidates decision-making under a single provider.
Broader Migration Wave
BitGo’s announcement reflects a broader shift in cross-chain infrastructure. Mantle, Lombard, Solv Protocol, Virtuals, Re, and Kraken have all announced LayerZero-to-Chainlink migrations. The earlier announcements covered $7.24 billion in value, with BitGo’s $7.3 billion addition bringing the total to approximately $14.5 billion.
WBTC represents a tokenized version of bitcoin designed to track its value and enable use in decentralized finance applications on other blockchains. The asset supports trading, lending, and collateral functions across multiple networks. According to CoinMarketCap, WBTC holds a market capitalization of $7.4 billion.
Control and Rate Limits
BitGo will retain control of WBTC token contracts and set rate limits and other controls governing transfers between blockchains. Chainlink’s directory already lists CCIP-enabled WBTC pools on Ethereum and Ronin, indicating infrastructure readiness for expanded deployments.
The migration does not specify a completion timeline for the broader WBTC transition to Chainlink CCIP across all supported networks.
