Supported USDC Networks
How USDC Payment Gateway Works
Our USDC payment gateway handles the entire transaction lifecycle. It generates a unique deposit address per order, monitors the chosen network for incoming funds, and notifies your backend via webhook the moment payment lands. USDC stays at $1, so there is no exchange rate calculation on your end.
Get Started-
1
Customer Selects USDC at Checkout
Your checkout page presents USDC as a payment option. The customer picks their preferred network from Ethereum, Solana, Polygon, or Arbitrum and sees the exact dollar amount to send.
-
2
We Generate a Unique Payment Address
Our API issues a dedicated deposit address on the chosen network, tied to the order amount, your merchant account, and a payment expiry window.
-
3
Customer Sends USDC
The customer sends USDC from any wallet to the generated address. We monitor all supported networks simultaneously and track the payment in real time.
-
4
You Get a Webhook and Funds Are Settled
As soon as the USDC transfer confirms on-chain, we send a signed webhook to your callback URL. Funds are credited to your merchant account right away.
