MMO Econ Mod (1.21.11, 1.21.1) – Trade Items and Run Server Shops

MMO Econ Mod brings a complete economy system with menu-based shops and player trading to your world. It runs on the server side, so players do not need to install any files on their game clients. You can trade items through graphical shop menus, list goods on a public auction house, and send money directly to other players. The mod also tracks balances on a leaderboard and lets server owners build custom shop categories using text files.

• Adds an interactive graphical shop for buying and selling blocks and items.
• Lets players send money directly to each other through chat commands.

• Displays a richest player leaderboard to show off top balances.
• Introduces sell wands that players can buy and use to clear chests for money.
• Grants money rewards to players automatically based on their playtime.
• Features an auction house menu where players trade items with each other.
• Works with modded items and Minecraft color formatting codes in shop files.

• /bal or /money: Displays your current balance.
• /pay <playername> <amount>: Sends money from your balance to another player.
• /bal top: Shows a list of the richest players on the server.
• /shop: Opens the main shop menu.
• /sell hand: Sells the item in your main hand if it is listed in the shop.
• /sell inv: Sells all shop-listed items currently in your inventory.
