What is NullCart?

NullCart is a free, open-source crypto shop you host yourself. You run it on your server with built-in non-custodial wallets - no payment processors in the middle. Buyers pay in crypto without accounts, and the storefront runs without JavaScript. You manage products and orders from a merchant CMS, on clearnet and Tor.
