Notch Currency Mod

A server-side economy mod for Fabric 1.20.1 with ATMs, player trading, and NPC shop integration.

Heavily inspired by the Origin Realms economy system. The core concept isn't mine, but all the code and assets are written from scratch. I'm still fairly new to modding so development may be slow — open to collaboration if anyone's interested.

• Auto-deposit when Notch Chips are placed in an ATM
