What's there? A simple script that fetches for you the prices from CoinGecko and creates a QR code.
You've to create a manual payment in your shopify store called "Crypto Payments" and add the script:
https://github.com/turinglabsorg/crypto-shopify/blob/master/src/ShopifyCode.md in your settings (custom scripts)
Add your own address just editing the first row:
window.CryptoAddresses = {
bitcoin: 'YOUR_BTC_ADDRESS',
kalkulus: 'YOUR_KLKS_ADDRESS',
ethereum: 'YOUR_XLM_ADDRESS',
binancecoin: 'YOUR_BNB_ADDRESS'
};
The only important things is that the first part (for ex. bitcoin) matches the coingecko one, you can try just putting your coin in this link:
https://api.coingecko.com/api/v3/coins/yourcoin
Here's a guide created by PirateChain that explains all the steps to activate the script (the guide is with the old version, but the steps are the same): https://medium.com/piratechain/piratechain-raises-anchor-on-the-shopify-plugin-6c5819726f07
