Cryptain lets your business take payments in BTC, ETH, USDT, USDC, BNB, POL, LTC, DOGE, SOL, BCH, XRP, TON and more. You create an invoice, a payment link or a button, or install a plugin; your customer pays from any wallet or exchange; we watch the blockchain and tell your website the moment the payment is confirmed.

Most businesses take their first payment the same day:

1. Open an account and confirm your email.
2. Add your website as a store. You get API keys and a webhook secret.
3. Install the plugin for your platform, paste the keys, and make a small test payment.

No website? Skip step 3 and send a payment link instead.

No. They pick a coin, scan a QR code or copy the address, and pay. Nothing to sign up for and no app to install.

Yes. Create a payment link or an invoice in the dashboard and send it by email, WhatsApp, Telegram or social media. You can also embed a donation button on any page.

Yes. Open Point of sale on any phone or tablet, type the amount in your currency and turn the screen to the customer. The page changes to "Paid" as soon as the payment is seen on the network. Staff can have their own cashier logins.

Yes. Our team installs and configures Cryptain on your website for a one-time $199, and makes the first test payment with you. Book the integration service.

BTC, ETH, USDT, USDC, BNB, POL, LTC, DOGE, SOL, BCH, XRP, TON, plus USDT and USDC on several networks. The full list is on the supported currencies page. You choose which ones each store shows at checkout.

The crypto amount is locked when the customer chooses a coin and stays fixed for the invoice's payment window. If they pay late, the invoice is marked late and your store settings decide whether to accept it at the original amount.

The invoice records exactly what arrived. You choose a small tolerance so a few cents of network fees never block an order. A real shortfall shows as underpaid, and the customer can top it up; an overpayment is marked so you can refund the difference.

It depends on the network. Tron, Solana, TON, Base and Arbitrum usually confirm in seconds; Bitcoin takes a block or two. Each network's confirmation count is shown on the currencies page.

The checkout shows the network in large type, with a warning, to prevent this. If it still happens, send the invoice link and transaction hash to support. Some mistakes can be recovered, some cannot; we will tell you which and what it costs.

Yes, when the checkout shows one. It is how we match the payment to the invoice. Customers paying from an exchange must enter the memo or tag in the withdrawal form.

Prices can be set in 20 currencies, including USD, EUR, GBP, INR, AED and more. The customer still pays in crypto; the amount is converted at checkout.

Yes. Set up a recurring invoice weekly, monthly, quarterly or yearly. We email the customer a payment link when each one is due, and they can see every bill in their customer portal.

Starter has no monthly fee: you pay 1% on each payment into your balance. Paid plans send payments straight to your own wallets with no per-payment fee. See the pricing page for the current plans.

The customer pays the network fee on the payment they send. When you withdraw from your balance, the network fee is shown before you confirm and taken from the amount sent. With own-wallet settlement there is no withdrawal at all.

With balance settlement payments land in your Cryptain balance and you withdraw when you like. With own-wallet settlement each payment goes directly to an address you control; we never hold it. Many merchants start with the balance and move to their own wallets as they grow.

Save a withdrawal address under Wallets, then choose Withdraw, enter the amount and confirm with two-factor authentication. New addresses are locked for 0 hours before first use, which protects you if someone gets into your account.

Yes. Turn on auto-withdraw for a coin and choose a threshold. When the balance reaches it, we send it to your saved address.

Yes. On plans with mass payouts, upload a CSV of addresses and amounts, check the preview, and confirm once with two-factor authentication.

Not through Cryptain. We settle in the coin your customer paid. If you want local currency, accept stablecoins such as USDT or USDC and convert them with an exchange you already use.

WooCommerce, WordPress, Easy Digital Downloads, WHMCS, Blesta, ClientExec, PrestaShop, OpenCart, Magento 2, Shopify and XenForo, plus SDKs for PHP, Node.js and Python. See all integrations.

Yes, a REST API with signed requests, idempotency keys and signed webhooks. You can create invoices, payment links and payouts, and read balances and rates. Read the API docs.

We retry failed webhooks with increasing delays for about a day. You can see every delivery and resend any of them from the dashboard, and you can always ask the API for an invoice's current status.

Yes. Each store can have its own logo, colour and name on the checkout. On supported plans you can also serve the checkout from your own domain, such as pay.yourshop.com.

Yes. Invite people with a role: owner, admin, finance, developer, support or cashier. Each person signs in with their own login and two-factor authentication, and every action is logged.

Yes. Connect Telegram to get a message for every payment and withdrawal, and to check balances from a chat.

Two-factor authentication, passkeys, alerts for new sign-ins, locks on new withdrawal addresses, signed API requests and webhooks, encrypted secrets and a full audit log. Details are on our security page.

Never. Own-wallet settlement only needs public addresses or an extended public key. Anyone asking for your seed phrase is trying to steal from you.

Depending on your volume and the way you settle, we may ask for ID and business documents before you can withdraw. It takes a few minutes. Our AML and Identity Policy explains why.

Anything illegal, plus a short list of high-risk businesses such as unlicensed gambling and financial schemes. Read the Acceptable Use Policy, or ask us before you start.

No. Confirmed blockchain payments are final, so there are no chargebacks. If you want to give money back, you send a refund from the invoice.

Open the invoice and choose Refund. Enter the customer's wallet address on the same network and confirm with two-factor authentication. The network fee is taken from the amount refunded.

Usually yes. Tax rules for crypto vary by country. Download your statements and CSV exports from the dashboard and give them to your accountant.

Use the chat in the corner, open a ticket from your dashboard, or send a message. For larger projects you can book a call with our team.
