FabricClient and serverMIT LicenseOpen source1.21.4 – 1.21.11

What it does

Polym adds a coin system to the game, so servers that need a shared currency can use coins in place of trading by barter. Each coin is crafted from a recipe, and the mod includes 9 coin recipes plus one recipe that turns a common material into another item. The mod requires Create, which players may need to trade currency with each other.

Key features

  1. Coin currency

    Coins act as the currency players exchange for goods, which helps when a server lacks a common medium of trade.

  2. Nine coin recipes

    Nine crafting recipes produce coins, so players can make the currency from materials they already gather.

  3. Material crafting

    One recipe converts a base material into a crafted item, and other items can be crafted from the coins.
