Coin System
by xitspvpxx
Coin System is a server-side economy mod for Fabric that adds a coin balance, a shop, duels and death penalties to a Minecraft server.
What it does
Players earn coins from mob rewards, mining, quests and the other coin sources a server owner configures, and spend them in a shop with a UI that lists whatever items the server owner adds. Purchases check the player's inventory first: a buy only goes through when there is room for every item, and the player is charged only for the items actually received. A player with partial space gets only what fits, and the rest of the cost stays in their balance.
The mod ships with more than 15 commands for managing the economy, the shop and duels, along with tools for death-coin penalties. Server owners can change the shop layout and item list through configuration, though the author notes that manual UI editing is required for some changes. Coin System needs external libraries to run, which the author lists as a requirement alongside the Fabric loader.
Environment: only the server needs it, so players join without installing anything. Released under the MIT License, the code is not open source. The latest Fabric file is 2.0.0, built for 1.21.11 and published on 2026-08-27, and the project was first released on 2026-05-17. The author also keeps a public issue tracker and a wiki.
Key features
Shop with inventory checks
Buying checks free inventory space before charging, so players are never billed for items they cannot receive.
Coin sources
Coins come from mob rewards, mining, quests and other sources the server owner sets up.
Duels and death penalties
Duels between players and coin penalties on death can be enabled as part of the server's economy rules.
Commands for server control
More than 15 commands cover the economy, shop management and duel control, so administration stays on the server.
