Global Item Transfer System (Personal Chest & Safe Trading)

This suggestion adds a system to transfer limited items between worlds in Minecraft. An Additional Chest (global inventory) appears as an icon near the crafting area with 9 slots. Players can store items here and access them in other worlds, similar to how skins are saved.

Add a new item named “Personal Chest.” It is a placeable block. When a player first right-clicks it, it becomes locked to that player, and only they can access it.

A new Trading Table allows safe trading. Two players place items, and the trade only completes when both confirm, preventing scams.

XP can become an interactable item and be used as a currency. Players can store and trade XP along with items, creating an economy system.

To maintain balance, this system is disabled in Creative mode. Options like “Survival Chest Mode” and “Hardcore Chest Mode” restrict transfers between similar worlds.

A new button in world creating menu “Lock External Items” option can disable use of transferred items,if you want a new fully survival world and don't wanna use items from any other world.

This improves multiplayer with safer trading, connected worlds, player-run shops, jobs, and server economies.You could make your friends work for you if you are rich in Minecraft.
