Crypto top-ups that credit themselves

Give every customer their own top-up address. They send USDT, BTC or another coin whenever and as often as they like, and CoinsPay finds each payment, credits it with the customer’s id and tells your site. Made for hosting, VPN, games and any service with a user balance.

Why services use permanent addresses

  • Customers pay when it suits them

    The address stays with the customer. They save it in their wallet and top up as often as they like, without asking you for a new link.

  • Every payment tagged

    Whatever lands on the address, CoinsPay credits on its own and tags with the customer or order number. No more matching transfers against a statement.

  • Your site knows right away

    A webhook with the customer id reaches your server as soon as the payment is credited. Balances top up without an operator.

  • A widget that matches your site

    Colors, font, corner radius and texts adjust to your design. The customer sees their address and QR code right on your top-up page.

Code for your top-up page

A block with the customer’s data and a script that inserts the widget and fits its height. Your server signs the customer id with the widget secret (HMAC-SHA256); samples for Node.js, PHP, Python and Go are in the dashboard.

HTML
<div data-cpay-widget="WIDGET_ID"
     data-customer="CUSTOMER_ID"
     data-signature="SIGNATURE"></div>
<script src="https://widget.coinspay.app/widget.js" async></script>

What addresses and the widget can do

Settings that spare you manual reconciliation and support tickets.

  • An address per customer or per order

    Give a customer one address for all top-ups, or issue a new one for every order to see at once what the money was for.

  • One address for all EVM networks

    An Ethereum address also receives payments from BNB Smart Chain. If a customer picks the wrong network, the payment is still credited, on its own network and flagged.

  • An address page

    Every address has a payment page with the QR code, network, an amount calculator and payment history. Just send the customer the link.

  • Amount in the widget

    Turn on the amount field and the customer sees how many coins to send. For Bitcoin, Litecoin and Solana the amount goes into the QR code too.

  • Only the coins you want

    Offer every coin, stablecoins only or a list of your own.

  • A separate domain for the widget

    The widget loads in an iframe from a separate domain that has no dashboard sign-in and none of your data.

Frequently asked questions

All questions
How is a permanent address different from an invoice?

An invoice is a one-off payment with an amount and a deadline. A permanent address accepts any amount any number of times, which suits balance top-ups and recurring payments.

How does my site know who topped up?

Every payment arrives as a payment.* webhook with the customer or order number in the reference field. Your site credits the money by it.

Do I need a developer?

The widget needs access to your server, which signs the customer id with the widget secret. Ready-made signing code for Node.js, PHP, Python and Go is in the dashboard.

What if a customer sends coins on the wrong network?

On EVM networks the address is the same, so a payment from BNB Smart Chain to an Ethereum address is still credited, on its own network. On other networks the widget and the address page clearly say which network to use.

Can I accept top-ups in stablecoins only?

Yes. Choose “Stablecoins only” in the widget, and customers can top up only in USDT or USDC.

How many widgets can I create?

Up to 20 per shop. For example, one for balance top-ups and another for subscription payments.

How much does it cost?

Nothing extra: it comes with the plan. You only pay a fee from 0.3% per payout, and the rate goes down as your volume grows. For the first 10 days after your first payment, payouts up to $500 carry no fee.
