“Squeak Road” is a new app in the Umbrel app store that lets anyone run their own darknet market.
Just go to the app store and install the app, and you are now the admin of a darknet market.
You can share the onion address publicly so that buyers and sellers can find your market.
All payments and withdrawals use lightning network.
As the admin of your market, all you have to do is set the fee rate, and approve/reject listings from sellers.
