Stablecoin Checkout is StablePay’s hosted checkout product for one-time stablecoin payments. It gives merchants a payer-facing checkout experience for USDT and USDC without requiring the merchant to build wallet connection, chain selection, transaction monitoring, QR/address payment logic, or exception handling from scratch. Merchants create a checkout session from their backend, redirect the payer to a StablePay-hosted checkout page, and receive payment status updates through the dashboard and webhooks. StablePay handles the checkout UX, wallet and transfer instructions, on-chain monitoring, payment status detection, and exception visibility.Documentation Index

When to use it
Use Stablecoin Checkout when a customer is paying once for a defined purchase or balance update. Common fit examples include:- Ecommerce orders from a website or custom storefront.
- App or game top-ups where the payer needs a clear hosted payment page.
- Digital goods, content, services, bookings, and one-time account credits.
- Custom commerce flows where your backend owns order creation and fulfillment.
- Merchant systems that need stablecoin payment acceptance without building wallet infrastructure.

How it works
- Your backend creates a checkout session with amount, currency, order context, and redirect URLs.
- StablePay returns a hosted checkout URL.
- The payer opens checkout and selects a supported payment method, such as wallet connection or transfer / QR-style payment.
- StablePay presents payer-facing instructions and monitors the on-chain payment.
- StablePay updates the session status and sends webhook events so your system can fulfill the order.

Payment status and exceptions
Stablecoin Checkout is built for the realities of on-chain payments. Payers may send too little, send too much, pay after a session expires, or cancel before paying. StablePay detects and exposes these outcomes so merchants can avoid treating every chain transaction as a simple success or failure. Use webhook events and dashboard status together to decide when to fulfill, when to contact the customer, and when a manual review is needed.Important notes
- Stablecoin Checkout is for one-time payments only. It does not create subscriptions or future automatic charges.
- Payers do not need to create a StablePay account to complete payment.
- Blockchain payments are final once confirmed. StablePay can provide transaction records and event logs for merchant-customer communication.
- StablePay Checkout wallet and transfer payment coverage is maintained in Supported Wallets.
