✅ Minimum requirements

Layer	Requirement	Supported range	Note
☕ Java	JDK / JRE	17 LTS or 21 LTS	The JAR is distributed in two flavors: vault-2.1.0-java17.jar and vault-2.1.0-java21.jar. Do not mix versions.
📦 Server	Spigot / Paper / Purpur / Folia	1.8.8 – 1.21.x	api-version: 1.13 in plugin.yml, but the plugin shims handlers for 1.8.8.
🔌 SoftDepends	LuckPerms, PlaceholderAPI, SkinsRestorer	(any stable)	Not mandatory; if present, Vault auto-integrates.
🗄️ Database	YAML (default) / MySQL 8.0+ / MariaDB 10.6+	optional	MySQL requires storage.use_mysql: true and a schema + user with CREATE / INSERT / SELECT / UPDATE / DELETE privileges.
💾 RAM heap	Recommended minimum	1 GB for active MySQL	Default HikariCP pool = 10 connections.

📥 Installation (step by step)

1. Choose the correct JAR

   • For Java 17 servers → vault-2.1.0-java17.jar
   • For Java 21 servers → vault-2.1.0-java21.jar

2. Stop the server and place the JAR in your plugins/ folder:

   my_server/
   ├── spigot-1.21.1.jar
   ├── plugins/
   │   ├── PlaceholderAPI/
   │   ├── LuckPerms/
   │   └── Vault/           ← created on first boot
   │   └── vault-2.1.0-java21.jar   ← PASTE HERE
   └── ...
   

3. (Optional) Install neighboring plugins to activate integrations:

   • PlaceholderAPI.jar → enables %vault_balance_formatted%, etc.
   • SkinsRestorer.jar → heads in /pay work even if the server is in offline mode.
   • LuckPerms.jar → to manage vault.* permissions comfortably.

4. Start the server. You will see in console:

   [Vault] ========================================
   [Vault]   Vault v2.1.0 (Java 21 build)
   [Vault]   Internal economy + Vault API bridge
   [Vault] ========================================
   [Vault] Locale: en  → messages_en.yml loaded
   [Vault] Storage: YAML  (balances.yml)
   [Vault] PlaceholderAPI detected → registered 40+ placeholders
   [Vault] SkinsRestorer detected → enabled head resolution
   [Vault] Update check: latest = v2.1.0  (you are up to date)
   

5. Stop and edit plugins/Vault/config.yml with your values (see Config Reference →).

6. Start again and run from in-game or console:

   /eco give YourName 10000
   /balance

🔧 First boot: generated files

The first /reload confirm or first boot creates inside plugins/Vault/:

# Default structure (v2.1.0)
config.yml                  # General settings, currency, storage, loans, bank, discord
balances.yml                # YAML balance storage (when use_mysql: false)
bank.yml                    # Banking system balances (bank_balance per UUID)
loans.yml                   # Active / closed loans (YamlLoanStorage)
transactions/               # Folder with daily JSON logs (DailyJsonLogWriter)
    ├── 2026-09-02.json

✅ Post-installation checks

Run this checklist in-game (with OP or vault.admin):

Step	Command	Expected result
1	/balance	Shows Your balance: 0.00 $
2	/eco give Steve 5000	Steve +5000.00 $ (admin give)
3	/pay Steve 1000	If Steve is online, 1000 arrives instantly
4	/vault top	#1 Steve 5000.00 $
5	/vault bank deposit 3000	Deposited: 3000.00 $
6	/vault bank balance	Wallet: 3000.00 $ · Bank: 3000.00 $ · Total: 6000.00 $
7	/vault withdraw 500	You receive a paper (PhysicalNote) in inventory
8	/vault reload	Vault reloaded (language: en)

If everything works → proceed to configure Config Reference → and choose your language in Languages →.

⚙️ Enable MySQL (optional)

Edit config.yml:

storage:
  use_mysql: true
  mysql:
    host: db.myserver.com
    port: 3306
    database: vault_prod
    username: vault_user
    password: "YourSecurePassword123!"
    pool_size: 10

Restart and look in the log: Vault: MySQL connection pool OK (10 idle). If you see SQLException, check credentials, firewall, and that the schema exists (the plugin does not create the database; it does create the balances and tx_log tables).
