About this Mod

📦 Digital Chest (Fabric 1.21.11)

🚀 Next-Gen Storage, Zero Client-Side Hassle

Digital Chest redefines server-side storage by bridging the gap between powerful logistics and the vanilla experience. Built on the Polymer framework, it delivers a high-tech storage suite that requires no client-side mod installation.

Players can join with a standard vanilla client and immediately interact with tiered chests, shared networks, and advanced sorting GUIs.


💎 The Evolution of Storage

Forget cluttered basements filled with wooden crates. Digital Chest introduces a tiered progression system that scales with your resources.

Start with the expanded capacity of Metal Chests (Iron, Gold, and Diamond) and graduate to the Digital Chest: a high-density unit that can be upgraded from Iron all the way to Netherite, which offers unlimited storage.

Pro Tip: Need to reorganize? Apply an Ender Pearl upgrade to any chest to enable Inventory Retention, allowing you to break and move your entire storage setup without spilling a single item.


🎨 Global Connectivity: Dye-Linked Channels

The true power of Digital Chest is its Color Linking system. By applying dyes to your chests, you create private, frequency-based networks.

  • Shared Inventories: Every chest on the same color channel shares the exact same inventory.
  • Remote Synchronization: Build a deposit station at your mob farm and access those items instantly at your main base.
  • Team Collaboration: Coordinate with your faction by sharing specific color channels for communal resources.

⚙️ Advanced Automation: The Quantum Hopper

Take your technical builds to the next level with the Quantum Hopper, a dedicated block that interfaces directly with your color channel network.

Three Operating Modes

  • INPUT (Green): Extract items into the network
  • EXTRACT (Orange): Pull items out of the network
  • STOCK (Cyan): Keep a target inventory precisely filled

Precision Filtering

  • Utilize the built-in 9-slot whitelist filter to control exactly what enters or leaves your system.

Scaling Transfer Rates

Your automation speed upgrades with your storage tier:

  • Iron: 1 item / 8 ticks
  • Netherite: up to 64 items / 2 ticks

🔐 Security & Cross-Dimensional Access

Whether you are collaborating with a faction or guarding your personal loot, Digital Chest gives you complete control.

Private Chest System

Right-click any linked chest with a Digital Key to privatize the channel. You can easily grant or revoke access using a whitelist GUI that displays online player heads.

Remote Access

The Soulbound Digital Key lets you remotely open the last Digital Chest you interacted with in the same dimension.

The Quantum Key

Upgrade your Soulbound Digital Key to a Quantum Key using a Netherite Template to unlock cross-dimensional access. It force-loads the target chunk so you can pull your gear from the Overworld while exploring the End.


🖥️ A Smarter Interface & Built-in Crafting

The custom GUI is designed for speed and clarity. Instead of hunting through rows of items:

  • Integrated Search Bar: Quickly find what you need using anvil-based text input filtering
  • Smart Sort: Organize by type, count, or mod origin (settings persist per-player)
  • Deposit All: Instantly move matching items from your inventory into the chest
  • Toggleable Holograms: Project item counts and types directly above the chest for at-a-glance information

Digital Crafting GUI

No need to constantly back out of your storage to craft.

The integrated 3x3 grid features:

  • Seamless drag-and-drop functionality
  • Live recipe resolution
  • Shift-click to craft-all directly within the interface
