ZMC's Currency Mod

Players hold a balance of points that can be stored digitally through an ATM. A bank card is crafted from 3 lapis lazuli and 3 white concrete, and it is protected by a PIN. Each card holds its own deposit, so money stored on one card cannot be reached with another card. The ATM block, crafted from 4 iron ingots around redstone dust, can register new cards, deposit and withdraw money, reset a PIN and re-register a card that still holds funds. A counter in the top left corner of the screen shows the total amount in the wallet.

Server owners set the value of items with the conversionitem command, for example conversionitem minecraft:diamond 10, which makes one diamond worth 10 points. Moderator permission is required to run it. Exchange machines then convert items into points and points back into items at that rate. A point conversion block, crafted from 4 iron ingots around a diamond, lets players break points into smaller bills or combine them, such as turning a 100 point bill into 100 bills worth 1 point each.

The mod runs on the server alone, so players join without installing anything. It is published for NeoForge only, with 0.1.0 for 1.21.4 as the one release so far, and the author describes it as an early beta. Bugs can be reported to the author, and other loaders or versions may follow depending on demand. The code is not open source; it is released under All rights reserved.
