I am getting x-cart 5 for my online store. However, I would like to accept dogecoin or similar like cryptocurrency. Therefore, I need an extra module that build onto it. That module must have certain standard and comparable to other x-cart modules found there for me to accept it. Since I am selling digital goods most of the time, the payment module needs to be able to automate the whole process instead of pending for my approval. Flowchart: The payment module must allow me to upload .csv which contains a list of doge public addresses, and then assign each product with one doge public address and display that QR code next to it. It shall be one time used only. Whenever a buyer want to checkout and make a payment, the payment module must be able to check whether that assigned public address received that amount of doge coins from blockchain explorer usually with 6 confirmations then only release the digital product to the buyer. The digital product could be in the form of downloadable image/file/etc or one time used voucher code. So, the buyer has the choice to get it immediately from my site or receive it via email. It must be compatible with x-cart 5. You may get the closest module there and modify it to my needs.
To bid this project, the core requirement is you need to have extensive knowledge in X-Cart 5, Dogecoin and Block Explorer
