> How a BigCommerce store takes USDC and USDT with Mintage Pay, and how we connect it with you.

BigCommerce only lets its approved payment partners add a payment method inside the checkout. So on BigCommerce,
Mintage Pay works as **order first, then pay**: the customer places the order with a payment method named "Pay with
USDC/USDT (Mintage Pay)", the order confirmation page sends them to the Mintage Pay payment page, and the order moves to
**Awaiting Fulfillment** by itself when the payment is final.

There is nothing to download. We connect your store with you, one store at a time. To start, write to
[hello@mintagepay.com](mailto:hello@mintagepay.com) with your store's address.

Tested on 3 and 5 October 2026 on a BigCommerce trial store priced in US dollars, against the sandbox: install, link,
a guest order placed in the storefront, the hand-over to the payment page, payment, the return to the store, and the
order moving to Awaiting Fulfillment. A store priced in another currency and a cancelled order have not been run yet.

## What you need

- The store owner's login, to install an app.
- **Optimized One-Page Checkout** turned on. The hand-over from the order confirmation page needs it.
- A shipping method switched on for your customers' countries. Without one, BigCommerce's checkout stops at the
  shipping step.
- A store currency Mintage Pay supports: USD, EUR, GBP, CAD, AUD, CHF, JPY, MXN, BRL, INR, SGD, AED, PLN, SEK, NOK, DKK,
  NZD, ZAR, TRY, KRW, HKD, NGN, ARS, PHP, IDR, VND, PKR, EGP, BDT, KES, GHS, TZS, COP, CLP, PEN, UYU, PYG, BOB, DOP, GTQ, CRC, THB, MYR, TWD, LKR, NPR, KZT, UAH, ILS, SAR, QAR, CZK, HUF, RON, ISK, XAF or XOF. Your customers always pay in US dollar stablecoins: a price in another currency is
  converted when the order is placed. The customer must be charged in the currency the store shows them.
- A Mintage Pay account with at least one payout address set.

## Connect your store

1. We send you an install link for the **Mintage Pay** app. Open it as the store owner and install the app.
2. The app's page in your control panel shows **Connect to Mintage Pay**. Click it and sign in to your Mintage Pay
   dashboard. The store now appears there under **Store connections**.
3. In the control panel, go to **Settings > Payments > Offline payment methods**. Switch one on, for example Bank
   Deposit, and rename it **Pay with USDC/USDT (Mintage Pay)**. The name must contain the word "Mintage Pay": that is how
   your orders are recognised.
4. Place a small test order and choose that method. The order confirmation page opens the payment page. Pay, and check
   that the order becomes **Awaiting Fulfillment** with a staff note.

## Try it first with test money

Ask us for a sandbox connection. Your store is then linked to a free account at
[sandbox.mintagepay.com](https://sandbox.mintagepay.com), the payment page shows a **Test mode** banner, and you
pay with free test money. The page has a button to get some. When you are happy, we link the store to your live
account.

## What you will see

| What happened | Order status |
|---|---|
| Order placed with the Mintage Pay method | Awaiting Payment |
| Paid in full | Awaiting Fulfillment, with a staff note naming the payment |
| Order cancelled or refunded in BigCommerce | Left as it is. A payment that arrives afterwards does not reopen it, and you get a notice |

The customer is sent to the payment page a few seconds after the order confirmation page loads, and comes back to
your store when the payment is seen.

Mintage Pay never holds your money, so it cannot send a refund for you. Send the refund from your own wallet and record
it in the Mintage Pay dashboard.

## If something is wrong

- **Checkout stops before payment:** no shipping method is switched on for the customer's country
  (**Settings > Shipping**).
- **The order confirmation page does not open the payment page:** check that Optimized One-Page Checkout is on, and
  that the payment method's name contains "Mintage Pay".
- **An order was paid and did not update:** check under **Store connections** in the Mintage Pay dashboard that the
  store is still connected, then write to us with the order number.
- **The control panel asks you to update the app:** click **Update** on the app's page. This happens when we change
  what the app may do.

## Disconnect

Uninstall the app in your BigCommerce control panel. The store is disconnected from Mintage Pay and the script on the
order confirmation page is removed. Then switch off the renamed offline payment method.
