BitGo Shifts $7.4B of Wrapped Bitcoin to Chainlink as LayerZero Exodus Nears $15B

BitGo selects Chainlink CCIP for wrapped bitcoin transfers

BitGo has named Chainlink CCIP as the cross-chain infrastructure for Wrapped Bitcoin (WBTC), the largest bitcoin-backed token in decentralized finance. The custody firm announced on 4 August 2026 that it would move WBTC transfers away from its previous provider, LayerZero. BitGo plans to use Chainlink's Cross-Chain Interoperability Protocol (CCIP) by default for future assets it issues. The change does not affect how WBTC is backed or redeemed for bitcoin.

A $292 million bridge exploit triggered the migration wave

The switch follows a wave of departures from LayerZero across the industry. According to CoinDesk, the trend accelerated after a $292 million exploit of Kelp DAO's LayerZero-powered bridge earlier in 2026. That incident increased scrutiny of how cross-chain bridges are configured and secured. BitGo said security concerns drove its review of interoperability providers, and the company completed that review before making the switch public.

LayerZero-to-Chainlink migrations now approach $15 billion

BitGo's move adds WBTC to a growing list of assets leaving LayerZero. According to The Block, the announcement pushes the total value of announced LayerZero-to-Chainlink migrations close to $15 billion. Earlier migrations had already accounted for roughly $7.2 billion of that total. The figure reflects announcements rather than completed transfers, and BitGo has not said when its own migration will finish.

Wrapped bitcoin carries a $7.4 billion market cap

WBTC traded at $64,161 at the time of publication, up 0.7% over the past 24 hours (CoinPaprika, 5 August 2026). That price gave the token a market capitalization of about $7.4 billion. The token's price closely tracks bitcoin, which it holds on a one-to-one basis. WBTC launched in 2019 and remains a common way to use bitcoin inside Ethereum-based applications.

BitGo retains control of its token contracts

BitGo will standardize WBTC using Chainlink's Cross-Chain Token (CCT) standard, which lets the issuer keep ownership of its token contracts. The arrangement allows BitGo to set rate limits and other controls on transfers between blockchains. Each CCIP route is secured by at least 16 independent node operators, spread across different organizations and regions. BitGo said the design reduces the risk that a single failure could disrupt transfers.

"BitGo has long been built around a simple principle: security comes first. As we expand support for BitGo-issued assets across more chains, Chainlink CCIP gives us a proven, institutionally adopted interoperability standard that aligns with the controls, reliability, and risk management our clients expect from BitGo.", 4 August 2026. — Mike Belshe, CEO, BitGo

WBTC leads the wrapped bitcoin market

WBTC accounts for about 45% of the wrapped bitcoin market by value, according to The Block. Its closest rival, Coinbase's cbBTC, carries a market cap near $6 billion. WBTC has circulated since 2019 and once reached more than $15 billion at its peak. The move keeps WBTC's on-chain versions consistent across the networks that support it.
