Circle has introduced native USDC and its Cross-Chain Transfer Protocol (CCTP) on OKX's X Layer, extending the reach of its dollar-backed stablecoin to an Ethereum-compatible layer-2 network. The integration targets developers, businesses, and blockchain applications looking to access stablecoin-based payments, decentralized finance (DeFi), and other financial services without relying exclusively on bridged versions of USDC.

X Layer, developed by OKX, is built to support Ethereum-based applications while offering lower transaction costs and faster settlement times. Its infrastructure is designed for a broad range of use cases, including DeFi, payments, real-world asset tokenization, and emerging artificial intelligence applications. OKX ranks among the world's largest cryptocurrency exchanges by volume, giving X Layer a potential on-ramp to a substantial existing user base.

With the addition of native USDC, applications running on X Layer can now utilize USDC issued directly by Circle rather than bridged representations, improving access to Circle's payment and financial infrastructure. The launch follows a pattern Circle has pursued on other networks—including Arbitrum, Optimism, and Avalanche—where the company has progressively replaced bridged USDC tokens with natively issued versions to reduce counterparty and bridge risk.

Native USDC Expands Financial Applications

Native USDC can be deployed across DeFi platforms, payment services, trading applications, and other blockchain-based financial products. The integration also provides eligible businesses with access to USDC issuance and redemption through Circle Mint on X Layer, creating a direct connection to Circle's stablecoin infrastructure. Uniswap, the largest decentralized exchange by volume, supported native USDC on X Layer from launch, providing immediate liquidity venues for users.

The availability of native USDC is notable because bridged assets can introduce additional infrastructure requirements and dependencies when tokens are moved between blockchain networks. By supporting USDC directly on X Layer, Circle aims to simplify stablecoin usage for applications and businesses operating on the network.

X Layer will continue to support bridged USDC originating from Ethereum. However, Circle and X Layer ecosystem participants are encouraging applications and users to gradually transition to native USDC where appropriate.

The launch comes amid growing competition among blockchain networks to attract stablecoin liquidity and financial applications. Native stablecoins offer developers a more direct foundation for building payment systems, trading platforms, and decentralized applications that require reliable dollar-denominated liquidity. USDC remains the second-largest stablecoin by market capitalization behind Tether's USDT, and Circle's multi-chain expansion strategy reflects an effort to deepen USDC's presence across emerging networks.

CCTP Connects USDC Across Blockchains

In addition to native USDC, Circle has deployed its Cross-Chain Transfer Protocol (CCTP) on X Layer. The protocol enables USDC to move between supported blockchain networks without relying on traditional wrapped versions of the token.

CCTP operates by burning USDC on one supported network and minting an equivalent amount of native USDC on the destination network. This mechanism allows applications to transfer the stablecoin across participating chains while maintaining a native form of USDC on the receiving network.

Following the X Layer launch, CCTP is now available across 26 blockchains, and native USDC is supported on 36 networks. This gives developers broader access to USDC liquidity across multiple blockchain ecosystems.

The expanded connectivity is particularly relevant for applications operating across multiple networks that need to transfer stablecoin liquidity between them. It also supports developers building cross-chain financial products without requiring users to depend on multiple wrapped versions of USDC.

USDC Targets Payments and AI Transactions

Circle's expansion onto X Layer also supports payment-focused applications, including services from fintech companies, payment providers, and decentralized applications. The stablecoin can additionally be used by AI agents for automated transactions and settlement, extending USDC's potential applications beyond conventional blockchain finance.

Our Wallet now supports a native @USDC on X Layer. Send, receive, use, and move USDC cross-chain via CCTP, with access across the broader X Layer DeFi ecosystem. Fully reserved, 1:1 redeemable, and MiCA-compliant. Supported from day 1 by @uniswap. — OKX Wallet (@wallet) August 7, 2026

The MiCA compliance referenced in the announcement aligns with the European Union's Markets in Crypto-Assets regulation, which establishes licensing and reserve requirements for stablecoin issuers operating in the bloc. Meeting these standards positions USDC for regulated use within EU markets as the framework takes effect.

The integration connects with X Layer's x402 ecosystem, designed to facilitate automated payments between AI agents and digital services. Developers can use USDC in transactions involving application programming interfaces (APIs), software-based services, and other automated activities.

For businesses meeting Circle's eligibility requirements, access to Circle Mint on X Layer offers an additional channel for issuing and redeeming USDC, which could support institutional settlement and other commercial applications requiring dollar-denominated digital assets.

The X Layer integration strengthens USDC's role across DeFi, payments, and automated AI transactions while providing businesses with a direct route to Circle's stablecoin infrastructure.

The launch forms part of Circle's broader blockchain infrastructure expansion. The company has also announced founding validators for its Arc blockchain, including major financial and technology firms. The continued development of these networks reflects Circle's strategy of expanding USDC connectivity and infrastructure as demand for blockchain-based payments and financial applications grows.
