There is only client integration in Shopify, No bitcoin based payment processing service in the Shopify backend. Shopify is still debt based e commerce world where the assumption that you actually have money to run your business with is a fallacy. It is basically designed to trick people into advertising on google facebook, Kind of an accuracy through volume strategy where you can count on stupid people scrolling on their couch to buy stuff they don’t need. Very little consideration for capital efficiency. LNBITS is the closest thing to a bitcoin store and that only offers custodial wallet solutions. Really wish there was a btcpay server integration for LNBITS to send payments directly to cold storage. I think I saw a section for a reduced price sale event in the Shopify platform, I think it would be a way to offer a bitcoin discount. When you are clicking through it is the very last page when you are checking out, Where on other sites you enter your card information that you have the option to pay in bitcoin. I think open node is the client Shopify uses most to integrate bitcoin payment. Whole thing is a debt based e commerce scam designed to make people take on debt in my opinion. Stupid people will buy anything. I was going to sell products featuring my art and realized how much money I was going to waste advertising instead of stacking. The “clear web” is a surveillance platform designed to sell people things they may or may not need and should be approached with skepticism.
