Most crypto payment tools were built for crypto people. Cryptain is built for businesses: the hosting company chasing renewals from customers whose cards keep failing, the software shop selling licences in forty countries, the agency that waits two weeks for an international transfer to clear.
Here is what you get on day one.
A checkout customers finish
The customer picks a coin, sees the exact amount, the network in plain words and a QR code. The page updates by itself when the payment is seen on the blockchain, and again when it is confirmed. No sign-up, no browser extension, no "please email us your transaction hash".
Prices stay in your currency. The crypto amount is locked when the customer chooses a coin, so a price swing in the middle of paying never turns into an argument.
Thirteen networks, the stablecoins people actually hold
Bitcoin, Ethereum, Tron, BNB Smart Chain, Polygon, Solana, TON, Arbitrum, Base, Litecoin, Dogecoin, Bitcoin Cash and the XRP Ledger. USDT and USDC are available on every network where they have real liquidity, which matters: a customer holding USDT on Tron will not bridge it to Ethereum to pay you.
Two ways to settle
- Balance settlement. Payments land in your Cryptain balance. Withdraw whenever you like, to addresses you have saved and locked.
- Own-wallet settlement. Each payment goes straight to an address you control, derived from your extended public key or taken from your list. We never touch the funds.
You can choose per store, so a marketplace can keep seller funds in balance mode while its own subscription revenue goes straight to a hardware wallet.
Plugins for what you already run
WooCommerce, WordPress, Easy Digital Downloads, WHMCS, Blesta, ClientExec, PrestaShop, OpenCart, Magento 2, Shopify and XenForo. Developers get a signed REST API, signed webhooks with automatic retries, and SDKs for PHP, Node.js and Python.
The rest of the toolkit
Payment links and donation buttons for when there is no shop. Invoices and recurring invoices with a customer portal. A point-of-sale page that turns any tablet into a terminal. Mass payouts from a CSV file. Team roles, two-factor authentication everywhere, a full audit log and Telegram alerts.
Start small
Opening an account costs nothing. Create a store, send yourself a one-dollar invoice, pay it from your own wallet on a cheap network such as Tron or Solana, and watch it land. Open an account, or book a call if you would like us to walk you through it.
