Points of Focus
- BitGo is migrating $7.4 billion WBTC from LayerZero to Chainlink CCIP, pushing total announced migrations to nearly $15 billion.
- The move follows the $292-million KelpDAO bridge exploit that triggered a broader reassessment of LayerZero’s security model.
- Chainlink CCIP will become BitGo’s default cross-chain infrastructure for future tokenized assets.
BitGo is replacing LayerZero with Chainlink’s Cross-Chain Interoperability Protocol (CCIP) as the cross-chain standard for Wrapped Bitcoin (WBTC), marking one of the largest infrastructure migrations in decentralized finance (DeFi) and bringing the total value of announced LayerZero-to-Chainlink migrations to nearly $15 billion.
The move covers WBTC, the largest wrapped Bitcoin token with a market capitalization of roughly $7.4 billion. BitGo also said Chainlink CCIP will become the default interoperability layer for all future digital assets issued by the company, extending the partnership beyond WBTC.
NEW: @BitGo (NYSE: BTGO) migrates $7.7B+ Wrapped Bitcoin (WBTC) to Chainlink CCIP.
After a rigorous review, BitGo deprecated its legacy bridging provider & chose CCIP as its exclusive cross-chain infra given it’s the only solution that meets institutional security requirements. https://t.co/ceIBKawZm8 pic.twitter.com/oEYtZtNuFU

The transition represents a major shift for tokenized Bitcoin infrastructure. WBTC has long been the dominant wrapped Bitcoin asset, allowing Bitcoin (BTC) holders to use their coins across DeFi applications for lending, borrowing, trading, and collateral while maintaining a one-to-one backing with native Bitcoin.
Security concerns accelerate the shift away from LayerZero
BitGo’s decision comes after months of growing scrutiny surrounding LayerZero following the $292-million exploit of KelpDAO’s rsETH bridge earlier this year.
The attack targeted a LayerZero bridge configured with a single Decentralized Verifier Network (DVN). After compromising the offchain infrastructure supporting the verifier, attackers were able to forge a cross-chain approval message and drain hundreds of millions of dollars in assets.
Although LayerZero maintained that the incident resulted from an application-specific security configuration rather than a flaw in the underlying protocol, the exploit prompted many projects to reassess their bridge architecture.
Subsequent ecosystem analysis found that a significant share of LayerZero applications relied on similar single-verifier configurations, raising broader concerns about implementation risk rather than protocol design itself. LayerZero later introduced changes to eliminate one-of-one verifier setups, but by then, several high-profile protocols had already begun planning migrations.
Before BitGo’s announcement, projects including Mantle, KelpDAO, Lombard, Solv Protocol, Virtuals, Re, and Kraken had already committed to migrating cross-chain infrastructure to Chainlink’s CCIP. With WBTC joining that list, the cumulative value of announced migrations has climbed to $14.6 billion.
WBTC strengthens Chainlink’s institutional footprint
For BitGo, the migration extends beyond replacing one bridge provider with another.
Under the new structure, BitGo retains ownership and control of WBTC while using Chainlink CCIP to move tokens across supported blockchains. The company can continue managing transfer limits, permissions, and token issuance while relying on CCIP for message verification and interoperability.
Chainlink has positioned CCIP as infrastructure built for institutional assets, emphasizing decentralized validation, configurable rate limits, and multiple security layers designed to reduce the risk of large-scale bridge exploits.
The migration also follows growing institutional adoption of CCIP across tokenized assets, stablecoins, and real-world asset (RWA) platforms, as traditional financial firms increasingly prioritize security over speed when selecting interoperability infrastructure.
Bridge security has become the industry’s biggest battleground
Cross-chain bridges have historically represented one of crypto’s largest attack surfaces, accounting for billions of dollars in losses over recent years.
As more institutions bring tokenized assets onchain, infrastructure providers are increasingly being evaluated on their security models rather than transaction throughput or blockchain coverage alone.
BitGo’s decision illustrates that shift. Instead of focusing primarily on expanding WBTC to additional networks, the company is prioritizing a security architecture designed for large-scale institutional assets.
For Chainlink, adding WBTC significantly strengthens its position in the rapidly growing interoperability market. For LayerZero, the departure of the largest wrapped Bitcoin token underscores how security incidents can reshape infrastructure decisions long after the underlying vulnerability has been addressed.
The migration also reflects a broader industry trend. As tokenized assets continue expanding beyond cryptocurrencies into stablecoins, private credit, and traditional financial products, interoperability providers are increasingly competing on trust, resilience, and institutional-grade risk management rather than simply connecting more blockchains.
