Vertcoin is almost a drop-in replacement for Bitcoin so if you already support Bitcoin, Vertcoin should be trivial to support. You can add yourself to our merchant list by visiting us on discord or on the Vertcoin subreddit.
Payment gateways accept Vertcoin on your behalf and give you your national currency in return. CoinPayments is currently the preferred method of accepting Vertcoin for your online business. CoinPayments charges a 0.5% fee for its services and has integrations with various popular e-commerce platforms including WooCommerce, Shopify, Xcart, drupal and wordpress.
