USDC (USD Coin) is a stablecoin issued by Circle whose value is pegged 1:1 to the US dollar. Each USDC in circulation is backed by a corresponding dollar held in regulated US financial institutions, with monthly third-party attestations. USDC is widely used in DeFi, cross-border payments, and institutional settlement due to its regulatory clarity and transparent reserve structure.

USDC on Noxpay

Noxpay supports USDC on three networks:
Currency codeNetworkNotes
USDCEthereum (ERC-20)Uses 0x... addresses.
SOL_USDC_PTHXSolanaUses base58 addresses.
USDC_AVAXAvalanche C-ChainUses 0x... addresses — same format as Ethereum.

​
Cross-network risk

Ethereum and Avalanche C-Chain both use 0x... address format. A USDC (ERC-20) address and a USDC (AVAX) address are syntactically identical. Sending USDC on Ethereum to an address that is only configured on Avalanche (or vice versa) will result in the funds being broadcast on the source network but not credited on the destination. The funds cannot be recovered. Always confirm the target network with your recipient before withdrawing.
