Rexpax is World's largest platform for sharing items. The Rexpax app is a new service that makes the world better. It materializes the idea of the sharing economy. You distribute all the items in your home onto virtual “shelves” and “rooms” so that your neighbors feel free to share them with you. You rent out, give away, sell and share items from your virtual rooms to your neighbours and strangers. All the transactions are stored in the blockchain register and it stimulates the participants to honest dealing.
