Uykucu's Coins
by uykucu
Uykucu's Coins adds a tier-based coin economy in which players convert currency between denominations with right-click and shift-right-click actions.
What it does
Coins come in several tiers with a clear order of progression. A higher-tier coin is crafted from lower-tier ones, and the reverse conversion is always possible by sneaking. Conversions are triggered with a plain right-click, while shift-right-click covers the reverse direction, and a GUI can also handle currency conversion at exchange rates the server owner sets.
The mod is built for economy-based servers, roleplay worlds, medieval-themed maps and custom trading systems. Its structure leaves room for later additions such as banker NPCs or exchange blocks. It is lightweight, keeps vanilla behavior intact, and is meant to be added to existing worlds and modpacks without much setup.
Files exist for Fabric and Forge, both for 1.21.1. Every player and the server need a copy of the mod. The mod is released under the MIT License and is not open source.
Key features
Tiered coin progression
Several coin tiers with clear progression, so players can move between denominations as their economy grows.
Right-click exchanges
Right-click and shift-right-click actions convert coins, and higher tiers are created by combining lower-tier coins.
Safe conversion
If the inventory is full during a conversion, the remaining items are dropped on the ground rather than lost.
GUI currency conversion
A GUI-based conversion screen applies configurable exchange rates between the coin tiers.
