Digital Chest

Digital Chests are infinite server-side storage blocks. Each chest can hold up to 9.2 quintillion of any item type — all hidden behind a clean GUI with search, sorting, and in-chest crafting. Everything works on vanilla clients via Polymer.

Getting Started

Craft a Digital Chests Handbook from a Book and an Ender Pearl to get the full in-game guide.

The base Digital Chest stores up to 90 unique item types. Upgrade it through four tiers using the smithing table to unlock more slots and faster automation.

Tier System

Digital Chests have four upgrade tiers. Each tier increases the number of unique item types the chest can store:

Tier	Max Item Types	Upgrade Material
Iron (Base)	90	—
Diamond	450	Diamond
Emerald	1,800	Emerald
Netherite	Unlimited	Netherite Ingot

Every item type can hold a full Java long count (9,223,372,036,854,775,807). Breaking a chest retains its full inventory.

Color Channels

Digital Chests use 16 dye color channels to link chests together. Dye a chest with any of the 16 Minecraft dyes to assign it to that channel — all chests on the same channel share inventory.

Link a chest to a channel by right-clicking with an Ender Pearl . Unlink by sneak-clicking with an empty hand.

Private Channels

Shift-right-click a linked chest with a Digital Key to make it private. Private channels are per-player — only you can access them. A whitelist GUI lets you grant access to other players.

Metal Chests

For players who want traditional slot-based storage, Metal Chests offer expanded vanilla-style inventories:

Metal Chest	Slots
Iron Chest Iron Chest	36
Gold Chest Gold Chest	45
Diamond Chest Diamond Chest	54

Metal Chests can also be linked to color channels with an Ender Pearl.

Digital & Quantum Keys

Digital Key Digital Key — Soulbound remote access to your linked chest. Works within the same dimension.
Quantum Key Quantum Key — Cross-dimensional access. Force-loads the chest’s chunk briefly to complete transfers.

Quantum Hopper

The Quantum Hopper is the automation backbone. Place it adjacent to any inventory and configure it for one of three modes:

Mode	Color	Behavior
INPUT	Green	Pushes items from the adjacent inventory into your Digital Chest channel
EXTRACT	Orange	Pulls items from your channel into the adjacent inventory
STOCK	Cyan	Maintains a target item count in the adjacent inventory

Each hopper has a 9-slot filter (whitelist or blacklist). Transfer rates scale with tier:

Tier	Items/Transfer	Tick Interval
Iron	1	8 ticks
Diamond	4	6 ticks
Emerald	16	4 ticks
Netherite	64	2 ticks

Quantum Furnace

The Quantum Furnace is a networked smelting block. It reads items from your Digital Chest channel, smelts them, and returns results — all automatically.

It has three filter rows and three operating modes (AUTO, IMPORT, EXPORT). Block controls let you configure which items to smelt without opening a GUI.

GUI Features

The Digital Chest GUI shows 45 item slots per page with full mouse-wheel scrolling. Features include:

Sort — by name, count, or mod
Search — real-time text filter
Deposit All — dump your inventory into the chest
Hologram Toggle — show/hide floating item labels above the chest
Crafting Terminal — a built-in 3×3 crafting grid that pulls materials from the channel. Shift-click to craft the maximum possible stack.

Pipe Integration

All Digital Chest blocks expose the Fabric Transfer API for seamless integration with Polymer Pipes and any other Transfer API-compatible mod.
