A lightweight, server-friendly marketplace mod that lets players trade with each other – no villagers, signs or commands required.
Drop a Bartering Station, choose what you want to sell, set a price, stock it, and you’re open for business!
The shops are protected from explosions and player griefing. Only operators or players with the luckperms permission "shoppy.admin.break_shop" can break shops that don't belong to them.
