Tochka Market

T•chka, rebranded as Point Marketplace, was a hidden service on the Tor Network that allowed you to buy and sell your items instantly—similar to Facebook Marketplace—without needing to communicate with other parties. Buy or sell the coordinates of your buried treasures, and finalize the trade only if you are satisfied with your purchase, or get your money back otherwise.
