Aukcion
by PelTuber
Aukcion adds a player auction house to a Fabric server, where players list items for sale and buy listings from each other through a shared trading screen.
What it does
Trading runs through a balance system: players pay and receive diamonds as a virtual currency, and a command converts diamonds into that balance and back, with a withdrawal menu for taking the currency out again. The auction itself opens with the aukcion command and gathers every listed item in one place that all players on the server can reach.
Server owners can run their own auction server with the mod, and admins get a cleanup routine that removes listings older than 24 hours, which keeps the house from filling with stale stock. A maxpredmetauk setting limits how many items each player may list. The mod is for servers that want a player economy around diamonds without an external shop, and it needs Fabric on the server and on each client. Files exist for 1.21.1 only, with 1.0.0 as the latest build, and the code is released under the MIT License, though the project is not open source.
Key features
Diamond-based balance
Diamonds convert into a virtual balance that pays for purchases and can be withdrawn again through a menu.
Item search
The aukcion search command lets players find listed items by name instead of scrolling the whole house.
Listing limit
The maxpredmetauk setting caps how many items each player can have on the market at one time.
Automatic cleanup
Listings older than 24 hours are removed by an admin cleanup system, keeping the auction house uncluttered.
