Description
Bigger, upgradable chests for Minecraft. Ten tiers from Christmas to Netherite, on Fabric and NeoForge.

Requires
- Iron Core Utilities (Fabric or NeoForge); for v3.0.0 and later
- Fabric API (Fabric only)
Chests
Each tier is a full block with a larger inventory than the last:
| Chest | Slots | Notes |
|---|---|---|
| Christmas | 27 | Vanilla-sized, festive |
| Dirt 9000! | 126 | Dirt only |
| Copper | 45 | |
| Iron | 54 | |
| Gold | 81 | |
| Diamond | 108 | |
| Emerald | 108 | |
| Crystal | 108 | See-through, contents visible from outside |
| Obsidian | 108 | Blast-resistant |
| Netherite | 126 | Blast-resistant |
Row counts are configurable per tier in config/ironchest.json. Each chest breaks like the material it's named after. An openUnderSolidBlocks setting in the same file lets chests open with a solid block above them.

Upgrades
Craft a Chest Upgrade and Shift + Right-Click a chest to upgrade it to the next tier, inventory included. No breaking, no moving stacks by hand. Works step by step from a vanilla chest all the way up.

Locks
Craft a Container Key and Shift + Right-Click a chest to lock it. Only you, players on the key, and operators can open, break, or upgrade it. Keys hold a trusted list editable at any time; one edit updates every linked chest. Locked chests block hoppers and all other automation.
Copper golems
Copper golems deposit carried items into any tier. They will only deposit dirt into the Dirt Chest 9000! Deposits can be switched off with copperGolemInteraction in config/ironchest.json.
