Struct USDC 

pub struct USDC;

Marker struct for USDC token deployment implementations.

This struct is used as a type parameter for chain-specific traits (e.g., KnownNetworkEip155, KnownNetworkSolana) to provide per-network USDC token deployment information.

Usage

Chain-specific crates implement traits for this marker struct to provide USDC token deployments on different networks. For example:

• x402-chain-eip155 implements KnownNetworkEip155<Eip155TokenDeployment> for USDC
• x402-chain-solana implements KnownNetworkSolana<SolanaTokenDeployment> for USDC
• x402-chain-aptos implements KnownNetworkAptos<AptosTokenDeployment> for USDC

Example

use x402_chain_eip155::{KnownNetworkEip155, Eip155TokenDeployment};
use x402_types::networks::USDC;

// Get USDC deployment on Base mainnet
let usdc_base: Eip155TokenDeployment = USDC::base();
assert_eq!(usdc_base.chain_reference.value(), 8453);
