Below is a good example of what details at your Cashier might look like:
Please note what details are shown to the customer:
QR code. To generate a QR code, it is necessary to use the content of the uri
parameter, which you received in your response when creating the invoice: "uri":"bitcoin:3Gtvf2EVxN8XJ4DHriRt9q9LkdVCpQZEeSd?amount=0.010268"
The QR code allows customers to make payments using a mobile device if the wallet is installed on it. The customer simply scans the QR code and the device opens the wallet with an automatically pre-filled payment destination address, which is a rather convenient method in the UX context
Payment amount in BTC
The address the payment should be sent to
The “Copy” buttons opposite the payment amount and address for customers’ convenience
Timer with a countdown of the time during which the payment is to be made
You can download cryptocurrency icons here. Alternatively, you can insert a ready hosted page with all the necessary payment details into your UI, which looks like this.
