Now Available: Native USDC and CCTP on X Layer

We’re excited to announce that USDC¹ and CCTP are live on X Layer.

X Layer is a Layer-2 (L2) blockchain from OKX that is EVM compatible and supports a wide range of use cases including payments, AI-native workflows, DeFi activity, and more. With over 120 million global OKX exchange users, Circle’s new X Layer integrations aim to bring expanded utility by delivering trusted, interoperable, and regulated¹ stablecoin infrastructure to OKX’s large and established trading ecosystem.

With the launch of native USDC and CCTP, X Layer gains access to a widely used and regulated¹ dollar stablecoin. This unlocks dollar-denominated payments, crosschain money movement, agentic commerce, DeFi lending and borrowing, and more on a blockchain designed for transaction efficiency and speed, EVM compatibility, and AI-friendly and institutional-grade workflows.

Benefits of USDC on X Layer:

• Regulated,¹ fully reserved stablecoin redeemable 1:1 for USD²
• Institutional on/offramps with Circle Mint³ for qualified businesses
• Easy integration with X Layer apps and protocols
• Dollar-denominated payments, DeFi activity, and AI-powered transactions

CCTP on X Layer enables developers to:

• Securely and efficiently move USDC between X Layer and other supported blockchains

Key use cases of USDC on X Layer

Native USDC can help establish a trusted dollar-denominated ecosystem on X Layer. With MiCA compliance, full reserve backing, and 1:1 redeemability for dollars,² USDC supports settlement, crosschain money movement, AI-powered workflows, and DeFi lending and borrowing. Establishing deep liquidity for USD/USDC trading pairs can support lower-slippage DeFi activity, settlement, and AI-driven applications at the scale institutions and enterprises need. Through CCTP, users and developers can move USDC securely across ecosystems.

Together, native USDC and CCTP can give businesses and developers on X Layer access to regulated¹ fiat rails for institutional-grade trading, programmable payments, and DeFi activity.

Popular X Layer apps include: OKX and OKX DEX Bridge.

Bridged vs native USDC on X Layer

X Layer also supports bridged USDC (USDC_Bridged), a non-native version of USDC that is bridged to X Layer from Ethereum. USDC_Bridged is not issued by Circle. The X Layer team plans to work with ecosystem apps and protocols to smoothly migrate USDC_Bridged liquidity to native USDC over time.

This gives X Layer the same native stablecoin features that are already available on other supported chains. There is no immediate impact to existing bridges and they will continue to operate normally. Bridged USDC will remain clearly labeled as “USDC_Bridged” in block explorers, app interfaces, and documentation.
