Installation

Requirements

Mod	Version
Lightman's Currency	exactly 1.21-2.3.0.5
One of:
FTB Chunks + FTB Teams + FTB Library	2101.1.21 / 2101.1.10 / 2101.1.32 or newer
Open Parties and Claims	0.27.5 or newer
NeoForge	21.1.234 or newer
Minecraft	1.21.1

If both FTB Chunks and Open Parties and Claims are installed, only the FTB integration is active — economy features that depend on FTB Teams (wars, bounties, marketplace, Pioneer Bonus, per-chunk permissions) won't be available through OP&C in that setup.

Version pinning

This mod hooks internal implementation details of Lightman's Currency and of whichever claim backend you use — not just their public APIs — and checks versions on startup:

• Lightman's Currency is checked as an exact match. It's a required dependency this mod is compiled against a large API surface of, where even a small version bump is more likely to carry a breaking change.
• FTB Chunks and Open Parties and Claims are checked as a minimum version. Earlier releases pinned these to an exact point version too, which meant every routine bugfix release of either mod broke this mod's loading until it was manually re-pinned. Since 4.4.0, any version at or above the minimum listed works.

If a requirement is missing or doesn't satisfy its check, the mod refuses to start and logs exactly which mod and version is wrong — check your log rather than guessing.

Steps

1. Download the mod jar and place it in your mods/ folder.
2. Install Lightman's Currency (exact version above) and either the full FTB Chunks/Teams/Library trio or Open Parties and Claims (minimum versions above) into the same mods/ folder.
3. Start the server (or single-player world). The config file is generated automatically on first launch at:

   world/serverconfig/lc_claim_economy-server.toml
   

   If a required companion mod is missing or too old, startup fails with a clear error naming the problem.
4. Tune the config to your liking — see Configuration.
5. In-game, follow Getting Started to walk through claiming, upkeep, and (if using FTB) wars and bounties.

Both sides required. Install the mod on every client as well as the server — it registers custom network payloads and client-side UI.
