Payment handling

CryptumPay helps customers complete their payments

Underpayments get topped up

If a customer sends too little, the checkout issues a top-up invoice for the difference — fees included — right in the payment window.

Overpayments get refunded

If a customer pays too much, they tap "Refund the excess" in the payment window and we handle the return with them directly. It never lands on your support desk.

The amount is worked out for them

Customers pick a coin, and the exact amount for that coin and network is calculated automatically — nothing to convert or mistype.

Any wallet customers use works

No app and no account to set up. Customers pay from whatever wallet they already use.

How it works

Customers pay in crypto, you always receive USDT

Website, Telegram bot, app, or a payment link — wherever you sell, it's the same four steps:

Customer pays

Major coins, from any wallet.

Confirmed on-chain

Your server gets a signed callback the moment it settles.

Credited as USDT

Converted as soon as it arrives, so your balance never sits in a volatile coin.

You withdraw

To your own wallet. Anytime, no minimum.

Q&A

Frequently asked questions

How much do I pay?

1% per successful payment. Down to 0.5% at higher volumes. You decide who covers the fees — you or your customer.

Always USDT. Whatever coin your customer pays, it's converted to USDT as it arrives, so your balance never rides the market.

Your balance is in USDT, and you withdraw to your own wallet whenever you want — no minimum. Withdrawals open once your project has passed review, usually within a business day of signing up.

The checkout handles it. If they underpay, it issues a top-up invoice for the difference, fees included. If they overpay, they tap "Refund the excess" in the payment window and we sort the return out with them directly — it never lands on your support desk.

For your customer, the rate is locked while they pay — the checkout timer runs on that rate. On your side, the incoming coin is converted to USDT the moment it arrives, so your balance never depends on the market. And the 1% fee is the only fee: what you see credited is what you keep.

No. They pay from any wallet they already have — through the widget, an invoice, or a payment link.

It’s paused before it reaches your balance, and you get a notification. Our team reviews the payment and resolves it — clean funds are credited, and anything risky stays isolated, so it never puts your balance or withdrawals at risk.

Popular coins and networks: BTC, ETH, USDT, TRX, BNB, SOL, TON, XRP, and more — including USDT across several networks.

Links need no integration — create one in the console and send it. The widget is one button that opens the full checkout on your site. The API is for building payments into your own product — your own interface, deposits, or backend.

Yes — you verify your domain with one DNS record. It’s a safeguard: your checkout can’t be used on someone else’s site.

Yes. Right after sign-up, create an invoice for a few cents and check the widget, the payment and the callbacks. Withdrawals open once your project has passed review.
