BitGo has selected Chainlink's Cross-Chain Interoperability Protocol (CCIP) as the exclusive cross-chain provider for Wrapped Bitcoin (WBTC), replacing LayerZero in a move that brings the total value of publicly announced migrations from LayerZero to Chainlink's infrastructure to roughly $14.6 billion. WBTC, with a market capitalization of about $7.4 billion, is the largest tokenized version of Bitcoin and a cornerstone of decentralized finance applications across multiple blockchains.
The migration will standardize WBTC deployments around Chainlink's Cross-Chain Token (CCT) standard, with BitGo retaining direct control over token contracts, transfer limits, and other operational settings. "BitGo has long been built around a simple principle: security comes first," said CEO Mike Belshe. "Chainlink CCIP gives us a proven, institutionally adopted interoperability standard that aligns with the controls, reliability, and risk management our clients expect." BitGo will also exclusively use CCIP for all future BitGo-issued assets.
The switch follows a wave of migrations after the $292 million exploit involving Kelp DAO's LayerZero-powered bridge earlier this year. Dozens of projects—including Kraken’s kBTC, Solv Protocol’s SolvBTC, Mantle, Lombard, and Aave—have moved to Chainlink CCIP. LayerZero's configurable Decentralized Verifier Network (DVN) had allowed clients to set a 1-of-1 verification, which attackers exploited in the KelpDAO incident. Analysts noted that 47% of LayerZero contracts were using such configurations at the time. Chainlink CCIP, by contrast, is secured by a minimum of 16 independent node operators and holds SOC 2 Type 2 and ISO 27001 certifications, with transfer protections like rate limits acting as circuit breakers.
The migration is part of BitGo's broader institutional push, which recently included the launch of treasury management platform BitGo Link and quantum-risk management tools for Bitcoin multisignature wallets. While the company has not disclosed a timeline for full deployment across all supported networks, the change reinforces the ongoing shift toward more robust cross-chain security in the wrapped Bitcoin market, where WBTC still accounts for about 45% of total market capitalization.
