Build Trusted, Interoperable Payment Systems with USDC and CCTP V2 on Codex

With the launch of native USDC and CCTP V2 on Codex Chain, developers now have access to a trusted, high-performance foundation for building payment-centric applications. This enables secure, interoperable, and permissionless onchain financial services, all powered by a regulated¹ digital dollar.

Codex, a purpose-built stablecoin native Layer 2, now supports natively issued USDC, backed 100% by cash and cash equivalent assets, and CCTP V2, the canonical protocol for moving USDC across supported chains via native minting and burning. Together, these two Circle technologies form the engine of a new generation of apps for interoperable payments, remittances, FX, and onchain financial infrastructure.

Native USDC: Secure, Trusted Dollar Access

USDC on Codex is not bridged or wrapped, and is backed by transparent high-quality reserves. For developers, this means direct access to the world’s largest regulated¹ digital dollar with instant composability on a chain optimized for stablecoin use.

Why it matters:

• Eliminates third-party bridge risk and wrapped asset fragmentation
• Provides secure, permissionless dollar access on a deterministic execution layer
• Enables composable payment, FX, and financial flows backed by trusted reserves

CCTP V2: Fast, Programmable, Canonical Transfers

CCTP V2 enables USDC to be burned on a source chain and minted natively on a destination chain, removing the need for synthetic assets or wrapped tokens. With support for Fast Transfers and Hooks, developers can build automated multichain money flows that can settle in seconds.

Why it matters:

• Enables secure cross chain USDC transfers between supported networks
• Supports programmable Hooks to trigger logic after funds arrive
• Forms the canonical infrastructure layer for multichain USDC movement
