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. 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
