SG-Economy API
by SirGrantd
SG-Economy API gives mods, modpacks and servers one shared way to store, read and change a numeric balance tied to each player's data.
What it does
The API defines an extensible economic system that other mods can use to define currencies, store balances and synchronize them to players. Balances are a persistent number kept with player data, so querying, setting, adding and removing values all go through the same interface. Developers can build custom economic systems on top of it, and the balance is a virtual wallet rather than a stack of in-game items, which means its name and purpose depend on the modpack that uses it.
Configuration files control how the economy behaves, including the currency format and how the balance is stored. Integer or decimal values can be chosen, which allows currencies with cents or other subdivisions. The documented classes and methods are supported by a GitHub repository with practical examples and implementation guides. Optional in-game commands let server owners manage balances, transfer them between players, and turn the commands on or off, while an optional display shows the balance in the inventory or on screen.
The mod runs on NeoForge for 1.21.1 only, with a single file, 1.0.5, published on 2026-05-31. It is released under a custom license and is not open source. It is one of 630 Economy mods that have NeoForge files for 1.21.1, and Magic Coins requires it.
Key features
Unified balance API
Mods read and change player balances through one interface, so each economy does not need its own storage code.
Custom currencies
Developers define their own economic systems, with currency names and value formats chosen by the modpack.
Integer and decimal values
Balances can use whole numbers or decimals, which allows currencies with cents or similar subdivisions.
Optional commands and display
In-game commands for managing balances and an inventory or on-screen balance display can each be enabled or disabled.
Documented developer resources
Documented classes and methods, plus examples and implementation guides in the GitHub repository, support integration work.

How it compares
EcoFlow is a client-side mod for NeoForge 1.21.1 under All rights reserved, and it needs the client but not the server, unlike SG-Economy API, which requires both. RC Economy and Createrington Currency both run on client and server for NeoForge 1.21.1, RC Economy under the MIT License and Createrington Currency under All rights reserved. Real Economy is server-side only, open source under the GNU General Public License v3.0 only, and covers Fabric, Forge and NeoForge for 1.21 – 1.21.10.
