Chainlink touts $15B in cross-chain migrations to CCIP

@chainlink says announced migrations to its Cross-Chain Interoperability Protocol (CCIP) have now crossed $15 billion, a milestone the network confirmed on Thursday after months of issuers pulling their cross-chain infrastructure away from rival providers.

The move that tipped the tally over the line came from BitGo, which announced on August 4, 2026 that it would shift $WBTC transfers away from LayerZero and use Chainlink CCIP by default for future assets it issues. The decision covers more than $7.7 billion of Wrapped Bitcoin, the largest omnichain fungible token by market capitalisation.

A Security Shock That Reshaped the Market

The migration wave has its roots in a single damaging incident. The rsETH bridge exploit on April 18, 2026 resulted in $292 million in losses, making it the largest DeFi exploit of 2026, with attackers draining 116,500 rsETH from the bridge escrow by forging a cross-chain message. The root cause was the protocol's 1-of-1 verifier configuration: only a single node was responsible for checking cross-chain messages before releasing funds, meaning the attacker only had to fool one verifier to approve a massive, fake transaction.

Attackers linked to North Korea's Lazarus Group carried out the theft, targeting off-chain infrastructure rather than smart contract code itself. The incident forced a broad reassessment of bridge security standards across the industry.

Various projects, including Mantle, Kelp, Lombard, Solv Protocol, Virtuals, Re, and Kraken, have since announced moves to Chainlink's CCIP. Mantle migrated more than $2.5 billion of MNT, Lombard Finance moved over $1 billion in Bitcoin assets, and Solv shifted more than $700 million in tokenised Bitcoin.

CCIP's Security Model as the Draw

Issuers citing security as the deciding factor have pointed to structural differences in how CCIP validates cross-chain transfers. BitGo CEO Mike Belshe framed the decision around risk, saying Chainlink CCIP offers "a proven, institutionally adopted interoperability standard" as the firm expands support for issued assets across more chains.

Chainlink's CCIP recorded more than $7 billion in token value migrating to its infrastructure during Q2 2026 alone, while quarterly CCIP volume reached $4.90 billion, up 353% year over year. The $15 billion figure reflects announcements rather than fully completed transfers, and BitGo has not said when its own migration will finish.

Industry tallies now put close to $16 billion of wrapped Bitcoin on CCIP, representing roughly 70% of all wrapped Bitcoin by circulating value.
