Portable Storage Unit (PSU) — Bedrock 1.21.131
Tired of overflowing chests and messy inventories? The Portable Storage Unit adds a craftable, handheld storage item that lets every player carry a personal stash anywhere — plus a built-in auction house for trading items with other players.
Key Features
-
Personal storage per player — your PSU inventory is yours and yours alone!
-
10 stack-slots of storage (each slot behaves like a real 64-stack; partial stacks fill first).
-
Safe storage rules — shulker boxes are blocked to prevent “storage-in-storage” abuse!
-
Market / Auction House built in
-
List trades like “6 diamonds for 20 copper Ingots”
-
10 active listings per player, cancel anytime before it sells (items drop back to you)
-
Global market (supports tons of sellers — listings aren’t capped by server, only per-player limits)
-
Offline-safe payouts — if you log out, sales still complete and your rewards wait to be claimed when you return.
-
Exact-match trading support
-
Trade specific enchanted books (exact enchant + level)
-
Trade tipped arrows and potions (exact effect)
-
Durability preserved and shown on listings (no “sell/buy to repair” exploits)
-
XP costs for fairness
-
Selling costs 2 levels
-
Buying costs 1 level
-
No XP = no transaction
