What is USDC

USDC is a stablecoin issued by Circle and intended to follow the US dollar. In a payment flow it is a digital asset on a particular network. A dollar order price and a USDC transfer remain different quantities: one describes the purchase price, the other the tokens sent.

For integration, distinguish the issuer's token on a network from representations transferred through bridges. Similar names do not make those assets interchangeable for a particular invoice. Check the network and exact identifier, rather than only the USDC label in a wallet.

Before paying, verify the recipient details and the option selected in the invoice. Preserve the returned address, amount, expiry and additional payment details without rebuilding them yourself. Network fees may require another asset and are not necessarily deducted from the USDC amount. Changing a token label cannot repair a wrong-network transfer.

In Cryptanio, use only options available for the particular operation. Circle's directory helps verify token identity, but does not establish integration readiness or network availability in your project. A page visit or sender's message does not complete payment: reconcile the transaction and confirmed state. Exchanging USDC for other assets is separate from accepting payment.
