Circle has deployed native USDC and its Cross-Chain Transfer Protocol (CCTP) on X Layer, the Ethereum layer-2 network operated by OKX. The Friday launch gives users and developers on X Layer direct access to Circle-issued USDC rather than a bridged or wrapped version, along with the ability to move the stablecoin between X Layer and every other chain CCTP supports without relying on third-party bridges.
X Layer is built as an EVM-compatible network, meaning Ethereum-based applications can deploy there with minimal changes to their existing code. CCTP works by burning USDC on the source chain and minting an equivalent amount natively on the destination chain, a design meant to avoid the liquidity fragmentation and security risks associated with wrapped-asset bridges.
A Bigger Push for Onchain Payments and DeFi
Circle positioned the integration as enabling a wider range of uses on X Layer, including payments, DeFi lending and borrowing, trading and crosschain transfers, with eligible businesses able to access USDC on- and off-ramps through Circle Mint. The move plugs X Layer into a stablecoin network that, by Circle's own account, already spans roughly 30 blockchains and has processed more than $126 billion in CCTP transfers to date — making native USDC one of the more consistently expanding pieces of crypto infrastructure through 2026.
For OKX, the integration adds another layer of liquidity depth to an exchange ecosystem that CoinMarketCap data placed fourth by spot trading volume, with roughly $975 million traded over the prior 24-hour period. USDC itself remains the second-largest stablecoin by market capitalization behind Tether's USDT, and expanding its native footprint across more layer-2s has been a consistent theme of Circle's strategy this year as it works to keep pace with rival stablecoin issuers moving onto the same networks.
Part of a Broader CCTP Overhaul
The X Layer rollout also comes as Circle pushes the ecosystem toward CCTP V2, which the company has established as the canonical version of the protocol and which adds a faster-than-finality transfer path along with deeper crosschain composability through what Circle calls Hooks. The legacy V1 version of CCTP began its phase-out on July 31, with a full contract pause to follow at the end of the deprecation window, meaning integrations like the one on X Layer are being built on the newer, more capable standard from the outset rather than requiring a later migration.

The deployment underscores how stablecoin issuers are increasingly treating layer-2 network support as table stakes, with Circle's native-first approach aimed at keeping USDC liquidity unified rather than splintered across a growing number of chains.
