Network fee for moving the coinsPaid in POL from your gas balance, with nothing added for sweeps. If the gas balance runs out, it's taken from the payment being moved.
Sent on another networkMay be lost for good. Customers must send USDC on Polygon, as the invoice shows.
Waits are typical times from the network's block interval, not guarantees. Every live coin and network: coins and networks.

What does a 100 USDC payment cost?

Our fee is 1 USDC (1%), so 99 USDC is credited to your balance. The Polygon network fee for moving the payment into your pool wallet is paid in POL from your gas balance, so it doesn't come out of the 99 USDC while your gas balance covers it.

Network fees change with how busy a network is, so we don't quote a fixed amount: how network fees work. Every price is on the pricing page.

Which USDC network should customers use?

Whichever one their wallet or exchange can send on, as long as you accept it: the network has to match the invoice. Crypto Merchant accepts USDC on 6 networks:

Network fees differ between networks and change with demand, so this table doesn't list amounts. Crypto network fees explained covers what each fee is and who pays it. You choose the networks you accept in the portal, and customers see only the ones you turn on.

How do USDC payments on Polygon work?

  1. 1

    Create an invoice or share your checkout

    Price it in your own currency. Send customers to your hosted checkout page, share a payment link, or create the invoice with the API.

  2. 2

    The customer picks USDC on Polygon

    The invoice shows the exact USDC amount, its own deposit address with a QR code, and a reminder to send only USDC on Polygon.

  3. 3

    Crypto Merchant waits for 64 confirmations

    That usually takes about 2 minutes. Then the invoice is marked paid, and your webhook, if you use one, is called.

  4. 4

    The payment is credited, and you pay out when you like

    Your balance grows by the payment less 1%. Pay out any time with no minimum, in USDC or swapped into one holding coin. See payouts and swaps.

Frequently asked questions

How long does a USDC payment on Polygon take to confirm?
Crypto Merchant waits for 64 confirmations on Polygon, which usually takes about 2 minutes. The invoice page updates on its own once the payment is confirmed.
Do I need POL to accept USDC on Polygon?
No. Moving USDC on Polygon costs a network fee in POL, and Crypto Merchant pays it from your gas balance, which starts with your one-time $25 go-live payment. If the gas balance runs out, the network fee is taken from the payment being moved.
What happens if a customer sends USDC on another network?
The invoice asks for USDC on Polygon only. The same coin on two networks is not interchangeable, and coins sent on another network may be lost for good, so customers should check the network before they send.
What does it cost to accept USDC on Polygon?
1% of each paid invoice, deducted in USDC when the payment is credited. There is no monthly or setup fee, and expired or cancelled invoices cost nothing. Going live takes a one-time $25 payment, credited in full to your gas balance, which isn't refunded as cash if you close your account.
What if the customer pays too little or too much?
If a payment is short by no more than your underpayment tolerance, it counts as paid. If it is short by more, the customer can send the rest to the same address or get a refund of what they sent, less the refund's network fee. If they overpay by more than $5, they can withdraw the extra from the invoice page; an overpayment of $5 or less goes to the Crypto Merchant platform pool and isn't returned.
Can I be paid out in another coin?
Yes. Pay out USDC to an address you save for it, or have your balance swapped into one holding coin first. Swap rates are based on live market prices and include a service margin. The network fee for a USDC payout is paid from your gas balance.
Do I need ID documents to start?
We don't ask for identity documents when you create an account: you sign up with an email address and a business name, from any country. The Terms of Service still apply, including the businesses and uses they prohibit.
