Native USDC And CCTP Introduced On OKX's X Layer

Circle Brings Native USDC to OKX's X Layer

@Circle's native $USDC stablecoin and its Cross-Chain Transfer Protocol (CCTP) are now live on @XLayerOfficial, the Ethereum Layer 2 network developed by @OKX. The integration gives X Layer direct access to a fully regulated, dollar-backed stablecoin and removes the need to rely on wrapped or bridged versions of USDC.

According to Circle, CCTP works by burning USDC on the source chain and minting fresh native USDC on the destination chain. There is no wrapped representation, no locked vault, and no third-party bridge custodian involved. The result for users and protocols on X Layer is native USDC that carries the same regulatory standing as USDC on any other supported network.

The launch enables 24/7 regulated settlement for DeFi applications and treasury management across 36 chains, with no exposure to the counterparty risks typically associated with bridged tokens. Circle reported that CCTP had processed $126 billion in cumulative volume as of December 2025, reflecting the protocol's growing role as core cross-chain infrastructure.

Powering the x402 Network and Machine Payments

Beyond standard DeFi and treasury use cases, the X Layer integration is designed to equip the x402 network, an emerging standard for machine-to-machine and HTTP-native payments. By providing native $USDC liquidity on X Layer, the launch aims to support automated commerce and programmatic payment flows that require a stable, interoperable settlement layer.

The move continues Circle's broader push to expand CCTP across high-performance blockchain ecosystems. CCTP V2, released in March 2025, added Fast Transfers settling in roughly 8 to 20 seconds, programmable post-transfer hooks, and Solana support. The protocol now connects more than 13 mainnet chains, with X Layer representing the latest addition to that network.
