What does it do? I’ve built a server-authoritative currency system for multiplayer Minecraft servers. Coins are numeric , stored per player server-side (can’t be spoofed client-side). Admins define exchange rates It works with weird denomination sets where greedy would fail It uses what the player actually has Players can exchange items into coins using a smart bounded knapsack solver It gets as close as possible to the requested value without going over Players can pay each other , and admins can mint coins . Rates are world-persistent , viewable by players, removable by admins, and now hardened to avoid legacy ID issues. Commands Admin / OP Commands (Requires Permission Level 2) Command Syntax Expected Result Quick Set (Hand) /coinhand [value] If value is empty: identifying the item ID in your hand. If value is set: Sets the exchange rate for the item currently in your main hand. Useful for mod items with complex IDs. Set Rate /coinrate <id> <val> Sets the value of a specific item ID manually. Fix Applied: Case-insensitive. simcraft:Silver now automatically becomes simcraft:silver . Unset Rate /coinrateunset <id> Removes the exchange rate for a specific item. Example: /coinrateu
