Turn ordinary barrels into interest-bearing vaults: deposit an item and it compounds every Minecraft day. Three flavors teach the full arc from saving to investing to getting scammed - a hands-on money lesson for a family or community server.
Three vault types (the recipe trim picks the type)
| Vault | Trim | Behavior |
|---|---|---|
| Savings | wood slabs | Fixed growth, compounds, never loses. |
| Stock | gold ingots | Volatile daily returns; red days remove items; rare market-wide crashes. |
| Hot Tip | gold blocks | "Guaranteed" absurd returns that periodically collapse to zero. The scam lesson. |
Features
• Per-deposit lots (like tax lots) reward dollar-cost averaging.
• Floating holograms show each vault's live balance (no resource pack needed).
• Every player gets an in-game Vault Investor's Handbook.
• One-switch difficulty: realistic / fun / crazy / custom, changeable live with /ibvault mode.
• Fully configurable rates, growable items, and recipes.
Install
Drop the jar into your server's plugins/ folder, restart the server fully (not /reload), then craft a barrel with the item to grow in the center and the trim that picks the type.
