+    money: 100
     commands:
-      - "eco give %player% 100"

-Commands run as the console, so no Vault/economy plugin is required by BlockParty itself —
-if you reference an economy command (like `eco give`) you need that plugin installed
-separately. `%player%`, `%arena%` and `%round%` are replaced before dispatch.
+Two independent reward mechanisms fire on a win, both optional:
+
+- **`money`** is deposited straight into the winner's balance through the
+  [Vault](https://www.spigotmc.org/resources/vault.34315/) Economy API — no console command
+  string parsing involved. This requires Vault **and** an economy plugin that registers a
+  Vault `Economy` provider (e.g. EssentialsX, CMI). If Vault or an economy provider isn't
+  present, BlockParty logs one warning and simply skips the money portion — it never crashes
+  and console-command rewards still run normally. Set `money: 0` to disable this entirely, or
+  `integrations.vault: false` to force-disable it even with Vault installed.
+- **`commands`** run as the console with `%player%`, `%arena%` and `%round%` substituted, for
+  anything beyond currency (items, permissions, external plugin hooks, announcements, etc.).
+
+Vault is declared as a `softdepend` in `plugin.yml`, so BlockParty starts up fine whether or
+not it's installed; the Economy service lookup happens fresh each time a reward is dispatched
+(not cached at startup), so plugin load order relative to your economy plugin doesn't matter.
