About this project
What does Rat Currency add?

Rat Currency
Tiered coins, pouches, and loot for a basic currency system. Configurable for a dedicated server / modpack environment if desired.
Note: Requires RatLib, a library mod to function properly.
Overview
Rat Currency adds a coin economy that other mods can share. Hostile mobs drop copper-value coins. You convert those coins up a ten-tier ladder, stash them in pouches and cases, and spend them anywhere a compatible mod asks for payment.
The point of the mod is not a shop of its own. It's to add a common currency with basic storage for it and a small API so traders, quests, and loot in other packs can all use the same coins.
Coins auto-combine as you pick them up. Wear or carry a pouch, and drops go straight into it instead of filling your inventory.
Coins
Ten coin tiers. Coins stack to 100 & will auto-convert to 1 of the next tier.

Copper → Silver → Gold → Platinum → Sapphire → Emerald → Ruby → Diamond → Obsidian → Netherite
- Craft 100 lower-tier coins into 1 next-tier up coin. Coins stack to 100.
- Craft 1 higher-tier coin back into 100 previous tier coins.
- Picked up coins will automatically craft into the next tier.
Compatibility
Required
- RatLib 1.0.7 or newer — shared library this mod registers its coin service with. Used by my other mods as well--always use latest unless stated otherwise.
Optional
- Curios 5.4 or newer
- Adds a Currency equipment slot
- Coin Pouch: Currency slot and Belt
- Coin Case: Currency slot and Hands
Tested with 500+ Forge mods, if you encounter any conflicts with other mods, please report the issue.
Custom Advancements
- "Hey, a wallet!" - Obtain a coin pouch
- "Time to buy Porygon" - Obtain a coin case
- "Greed" - Hold 100 Netherite Coins
Q & A
Will other Versions be supported?
Possibly. Definitely neighboring Forge & I could see a 1.21 NeoForge port in the future.
Can I use this in my modpack?
Absolutely! Just please credit if you do, but I encourage modpack use :)
