Overview
Tycoon Shop is a server-side economy mod for NeoForge 1.21.1. It adds a currency system, an admin-managed shop, a player-to-player marketplace, and wallet management tools.
Currency
Five coin tiers exist, each worth a configurable multiple of the one below it (default 100:1):
Copper Coin → Iron Coin → Gold Coin → Diamond Coin → Netherite Coin Coins are physical items that can exist in your inventory. When you deposit them into your wallet, they auto-convert upward — 100 copper automatically becomes 1 iron, and so on. When spending, higher-tier coins are broken down automatically to cover the cost.
Wallet
Every player has a personal wallet stored on the server. It persists through deaths and restarts.
Interacting with the wallet:
Left-click the wallet HUD button — opens the withdraw screen to take coins out as items Shift + Left-click the HUD button — deposits all coin items from your inventory into the wallet Right-clicking a coin item — deposits that stack directly into the wallet If FTB Teams is installed, teammates share a single wallet.
Tycoon Shop
An admin-managed store where players can buy items for coins. The shop is organized into categories and entries.
Admins open the shop with /tshop, then enable Edit Mode to:
Create, rename, reorder, and delete categories Add, edit, reorder, and delete item entries with custom prices and currencies Save the current shop layout as the server default Changes are applied live — no restart needed.
Player Market
A player-to-player marketplace where anyone can list items for sale.
Create a listing — select an item from your inventory, set a price and currency Buy a listing — coins are deducted from your wallet, item goes to your inventory Cancel a listing — the item is returned to your inbox Inbox — if you're offline when your item sells or you cancel a listing, coins and items wait in your inbox until you claim them Listings expire automatically after a set period Tax: every sale deducts a 5% tax from what the seller receives (minimum 1 coin for prices of 2+). Taxed coins are destroyed, reducing the money supply over time.
