Paid communities, cohort courses, private channels and member areas all come down to the same thing: after paying, the buyer needs a way in. That might be an invite link to a private Discord or Telegram group, a course enrolment link, or a unique access code for your members' area.
On ZappSell you add that link or code as the product's stock. When a buyer pays in crypto and the payment confirms, the access is emailed to them automatically. You host the community or course wherever it already lives; ZappSell handles the storefront, the crypto checkout and the delivery.
