How to accept crypto payments for digital products

Crypto is the one common way to pay that a buyer’s bank can’t reverse. For digital products, which arrive in seconds and can’t be sent back, that matters more than it does for a parcel. Crypto also reaches buyers whose cards get declined abroad and buyers who would rather not type card details into a store they just found. The trade-offs are real too: prices move, network fees rise and fall, and every refund is a transaction you send yourself. This page covers both sides and how to set up a crypto checkout that delivers on its own.

Why accept crypto payments for digital products

• No chargebacks from a bank. A card payment can be disputed weeks later. A confirmed crypto payment stays where it landed. ShopFast can’t pull it back either: refunds go out from your wallet or your processor.
• Buyers anywhere. A wallet works the same in every country, with no card network deciding whether a cross-border payment goes through.
• Paid straight to you. With your own wallet, the money never sits with a processor waiting for a payout.

What it costs you: some buyers have never sent crypto, a coin’s price can move between checkout and the moment you sell it, and a wrong network or a mistyped amount turns into a support conversation. Unless your buyers already hold crypto, offer it next to a card or PayPal option rather than as the only way to pay. Payment methods for digital products compares every option.

Your own wallet or a crypto payment gateway?

There are two ways to take crypto: watch your own wallet for incoming payments, or let a processor run the payment page and report back.

Setup	Custody	What you connect	Fees
Your own wallet	Self-custody: coins land in your wallet	Your wallet’s xpub or a receiving address	No processor fee and no ShopFast fee
BTCPay Server	Self-custody, on a server you run	Your server’s address, store ID and API key	Your own hosting
NOWPayments	Set by the processor’s terms	API key and IPN secret key	The processor’s own fees
Cryptomus	Set by the processor’s terms	Merchant ID and Payment API key	The processor’s own fees
Heleket	Set by the processor’s terms	Merchant ID and API key (Heleket approves you first)	The processor’s own fees

A self-custody crypto checkout means nobody can freeze or hold your balance, and also nobody can recover it if you lose your keys. Processors can offer more coins and their own dashboards and payout options; read each one’s terms and fee page before you pick. With a processor, buyers pay on its page and come back to their order afterward.

Which coins to accept

Wallet-to-wallet payments on ShopFast take BTC, LTC, ETH, USDC and USDT. They behave differently:

• Bitcoin (BTC) is the coin most buyers know. Confirmations take a while and network fees climb when the network is busy, which makes it a poor fit for very small orders.
• Litecoin (LTC) is usually quicker and cheaper to send, which suits small purchases.
• Ethereum (ETH) is widely held; its network fees move with demand.
• USDC and USDT are stablecoins meant to track the US dollar, so what you receive keeps its value while you hold it. For a store that prices in dollars, they remove most of the price risk.

Stablecoins exist on more than one blockchain, and coins sent on the wrong network are hard or impossible to recover. Tell buyers to send on exactly the network the payment page asks for.

What an xpub is, and how to share it safely

An xpub (extended public key) is a read-only key for one account in your wallet. Software that has it can work out that account’s receiving addresses and see payments arrive, but it can’t spend anything. That is why a checkout asks for an xpub and never for anything secret.

1. Never paste a seed phrase or private key into any website, ShopFast included. A checkout never needs them.
2. Use a separate wallet account for the store. An xpub reveals every address and balance of its account, so keep personal funds somewhere else.
3. Keep your backup safe. With self-custody, your recovery phrase is the only way back into the wallet.

If your wallet can’t export an xpub, a single receiving address works too.

Network fees, underpayments and late payments

Some wallets take the network fee out of the amount sent, so a payment can arrive slightly short. In Money → Payments → Crypto, under Price lock and edge cases, you choose how short a payment may be and still count: a share of the order, or a fixed amount for small orders where a share is only cents. A payment short by more than that waits: the buyer sees what arrived, what is still due and a countdown to send the rest. If the rest never comes, the payment is marked partly paid and waits for you to accept it or send the coins back.

Slow confirmations don’t cost you the sale either: a checkout that only ran out of time still delivers when its exact total arrives late. ShopFast watches the chain and hands over the key, file or access as soon as the payment counts, the same automatic delivery every other method gets.

Tiny crypto orders can cost the buyer more in network fees than the product is worth. Order limits let you offer crypto only from an amount, and cards only up to one (order limits).

Refunds and disputes when buyers pay in crypto

A crypto payment can’t be reversed by the buyer, their bank or ShopFast. A refund is a new transaction from your wallet or processor, so get the buyer’s refund address in writing and check it before you send anything.

Decide ahead of time whether you refund the coin amount or the price in your store’s currency, since the two drift apart when the price moves, and write that into your refund policy.

That same finality makes crypto a fraud tool for you. Fraud Shield’s chargeback shield can steer a risky checkout away from cards and toward crypto or store credit, and you can price crypto lower so buyers take the switch (Fraud Shield). The full playbook is in how to prevent chargebacks on digital goods.

Set up crypto checkout on ShopFast

1. Create a separate account in your wallet for store payments.
2. Open Money → Payments → Crypto and paste the xpub or a receiving address for each coin you take.
3. Set how short a payment may be, and a smallest crypto order in Checkout rules if you want one.
4. Place a small order on your store and pay it in crypto. It is marked paid, and delivered, once the payment counts.

Prefer a processor? Connect NOWPayments, Cryptomus, Heleket or BTCPay Server from the same page with the credentials in the table above (connect your own gateway). ShopFast takes no fee on orders paid to your own wallet or processor.

Crypto fits products that should arrive the second they’re paid, like license keys. For buyers who want to pay with crypto but don’t have a wallet, gift card payments with Binance USDT cards are a slower, reviewed alternative.
