Commands

Player Commands

• /bal [<player|selector>|top] - Check balances or view the top balances.
• /pay <player> <amount> - Transfer money to another player.
• /daily - Claim a daily login bonus.
• /shop - Player-driven marketplace where players list items for sale.
  • list <price> [<amount>] - List the item in your hand. Omit <amount> to list up to a full stack.
• /servershop - Server-managed shop with unlimited supply. Prices can be edited in config/economycraft/prices.json.
• /sell [<amount>|all|everything] - Sell the item in your hand. Use all to sell all matching items from your inventory, or everything to sell your entire inventory. If an open /orders request pays more per item than the server would, the sale goes there first (best-paying order first), falling back to the server price for any remainder.
• /orders - Request-based trading system. Click a request to fulfill it fully/partially.
  • request <item> <amount> <price> - Create an item request.
  • claim - Claim items bought or requested while offline.

Hover a filled shulker box and press Ctrl+Q to preview its contents before buying, selling, or fulfilling.

Admin Commands

• /eco addmoney <player|selector> <amount> - Add money to a player.
• /eco setmoney <player|selector> <amount> - Set a player’s balance.
• /eco removemoney <player|selector> [amount] - Remove money from a player.
• /eco removeplayer <player|selector> - Remove a player from the economy system.
• /eco toggleScoreboard - Toggle the balance sidebar for all players.

Notes:

• Non-admin commands such as /pay or /daily are standalone by default and also work under /eco (e.g., /eco pay).
  Set standalone_commands to false in config.json to require the /eco prefix.
• Admin commands use /eco unless standalone_admin_commands is enabled.

Configuration

Configuration and player data are stored in config/economycraft/.

Default config.json

{
  "startingBalance": 1000,
  "dailyAmount": 100,
  "dailySellLimit": 10000,
  "taxRate": 0.1,
  "pvp_balance_loss_percentage": 0.0,
  "standalone_commands": true,
  "standalone_admin_commands": false,
  "scoreboard_enabled": true,
  "server_shop_enabled": true,
  "sell_enabled": true,
  "balance_separator": "."
}

• startingBalance - initial money for new players. Default: 1000.
• dailyAmount - money given by /daily. Default: 100.
• dailySellLimit - maximum money a player can earn per day via selling. 0 disables the limit. Default: 10000.
• taxRate - percentage tax applied to trades and orders (decimal factor, e.g. 0.1 = 10%). Default: 0.1.
• pvp_balance_loss_percentage - percentage of a player’s balance lost on PvP death and transferred to the killer (decimal factor, e.g. 0.1 = 10%). 0 disables this feature. Default: 0.
• standalone_commands - enable standalone /pay, /daily, etc. Default: true.
• standalone_admin_commands - enable standalone /addmoney, /setmoney, etc. Default: false.
• scoreboard_enabled - show the balance sidebar by default. Can be toggled with /eco toggleScoreboard. Default: true.
• server_shop_enabled - enables the server shop (/servershop and /eco servershop). Default: true.
• sell_enabled - enables the /sell command (selling farmed items directly to the server). Set to false to steer players toward supply-driven trading via /shop and /orders. Default: true.
• balance_separator - thousands-separator character used wherever a balance is displayed (commands, menus, %economycraft:balance_formatted%). Only the first character is used, e.g. "," for $1,000. Default: ".".

Server Shop Prices (prices.json)

Each entry is keyed by an item id (vanilla or modded):

{
  "minecraft:enchanted_book": {
    "category": "enchantments",
    "stack": 16,
    "unit_buy": 800,
    "unit_sell": 200,
    "components": {
      "minecraft:stored_enchantments": {
        "minecraft:mending": 1
      }
    }
  }
}

• category - groups the entry in the shop menu. Use top.sub (e.g. blocks.wood) for a subcategory.
• stack - item's stack size
• unit_buy / unit_sell - price per single item; 0 disables that direction.
• components - optional, only needed for an item with specific NBT (custom name, enchantments, a shulker box with contents, etc.).
  • Tip: create the item as a /shop listing first, then copy its components object out of config/economycraft/data/shop.json.

A JSON key can only be used once, so normally you can only have one entry per item id. If you want to sell several versions of the same item (e.g. two different loot shulkers, swords with different enchantments, etc.), add a #label after the id to keep the JSON keys distinct; the label is discarded once the entry is read and never shown to players:

{
  "minecraft:shulker_box#loot_common": {
    "category": "custom",
    "unit_buy": 5000,
    "components": {
      "minecraft:custom_name": {"text": "Loot Box"},
      "minecraft:container": [
        {"slot": 0, "item": {"id": "minecraft:diamond", "count": 5}},
        {"slot": 1, "item": {"id": "minecraft:emerald", "count": 10}}
      ]
    }
  },
  "minecraft:shulker_box#loot_rare": {
    "category": "custom",
    "unit_buy": 15000,
    "components": {
      "minecraft:custom_name": {"text": "Rare Loot Box"},
      "minecraft:container": [
        {"slot": 0, "item": {"id": "minecraft:netherite_ingot", "count": 3}}
      ]
    }
  }
}

Placeholders

EconomyCraft can expose economy data to other mods through Text Placeholder API on Fabric, or its unofficial Placeholder API NeoForge port on NeoForge.

Both are optional and not bundled with EconomyCraft, the mod runs fine without them, but you must download the jar matching your Minecraft version/loader and drop it into your server's mods folder yourself before any placeholder below will resolve:

• Fabric: Text Placeholder API on Modrinth
• NeoForge: Placeholder API NeoForge on Modrinth

Placeholder	Description
%economycraft:balance%	Raw numeric balance of the viewed player (e.g. 1000).
%economycraft:balance_formatted%	Balance formatted with currency symbol and thousands separator (e.g. $1.000).
%economycraft:daily_sell_remaining%	Remaining amount the player can earn from /sell today before hitting dailySellLimit. Shows ∞ if the limit is disabled.
%economycraft:top_name 1%	Name of the player ranked 1 on the balance leaderboard (1 = richest). Not tied to the viewed player.
%economycraft:top_balance 1%	Raw numeric balance of the player ranked 1.
%economycraft:top_balance_formatted 1%	Formatted balance of the player ranked 1.

The top_* placeholders take the rank as an argument, separated from the placeholder name by a space (e.g. %economycraft:top_name 3% for 3rd place). If fewer players exist than the requested rank, the placeholder resolves as invalid.
