Config Settings Explained

General

• defaultBalance: How much money new players start with when they first join.
• currencySymbol: The symbol shown next to money amounts (e.g. "$", "€", "Coins").
• symbolBeforeAmount: If true, output shows $100. If false, output shows 100$.
• enableSellCommands: Turns the /worth, /buy, and /sell server market on or off.
• enableChestShops: Turns the player chest shop sign system on or off.

Storage Options

Controls how player balances are saved.

• storage.type: Choose how to save player balances. JSON is the default and is perfect for standard servers. Change this to MYSQL or POSTGRESQL if you run a large network.
• storage.host / port / database / user / password: Fill these in only if you are using MYSQL or POSTGRESQL.
• storage.tablePrefix: The prefix used for the database tables (default savs_eco_).

Redis Network Sync (Optional)

If you run a multi-server network, turn this on to sync balances between your servers.

• redis.enabled: Turn this to true to enable sharing balances across servers.
• redis.host / port / password: Your Redis server login details (Port is usually 6379).
• redis.channel: Make sure every server in your network has the EXACT same text here so they can talk to each other.

Chat Notifications

Controls how transaction messages appear to players. Set these to ACTION_BAR (shows briefly above the hotbar), CHAT (standard chat message), or NONE.

• apiNotificationMode: Messages triggered automatically by other plugins.
• commandNotificationMode: Messages from player commands like /pay.

Permissions & OP Levels

The mod supports LuckPerms (Recommended) and the Fabric Permissions API.

If you aren't using a permissions manager, we gracefully fall back to standard Vanilla OP Levels. Open the config/savs-common-economy/permissions.json file to easily change what OP level is required for each command. Most standard player commands default to OP level 0 (everyone), while admin commands default to OP level 2.

Here is a list of all current permission nodes you can change in the config:

Player Command Nodes (Default: Level 0)

• savscommoneconomy.command.bal: Access to /bal for checking your own balance.
• savscommoneconomy.command.bal.others: Access to /bal <player> for checking someone else's balance.
• savscommoneconomy.command.pay: Access to /pay.
• savscommoneconomy.command.withdraw: Access to /withdraw.
• savscommoneconomy.command.baltop: Access to /baltop.
• savscommoneconomy.command.worth: Access to /worth and /worth all.
• savscommoneconomy.command.sell: Access to /sell and /sell all.
• savscommoneconomy.command.buy: Access to /buy.

Shop Command Nodes (Default: Level 0)

• savscommoneconomy.shop.create: Access to create both buy and sell chest shops.
• savscommoneconomy.shop.info: Access to check shop details.
• savscommoneconomy.shop.list: Access to see all your active shops.
• savscommoneconomy.shop.remove: Access to safely break your own shops.

Admin Command Nodes (Default: Level 2)

All powerful administrative features are grouped securely under one single node constraint.

• savscommoneconomy.admin: Controls access to all admin features including /givemoney, /takemoney, /setmoney, /resetmoney, /shop admin, and /ecolog.

Chest Shops Setup

Chest shops allow players or admins to buy and sell items directly from chests.

How to create a Shop:

1. Place any chest container and insert items (if making a sell shop).
2. Look precisely at the chest while holding the precise matching item you wish to market.
3. Run /shop create sell 100 to create a shop that sells items to players for $100 per interaction unit.
4. Or, run /shop create buy 50 to create a shop that purchases items from players for $50 per interaction unit.

How to trade with a Shop:

1. Right-click any physical shop sign to begin a transaction.
2. Type in the chat the amount you want to buy or sell (e.g. type 10 or type all) and press enter.
3. Receive your items or money.
