Tycoon Shop

Coins come in five tiers: Copper, Iron, Gold, Diamond and Netherite. They are physical items kept in the inventory, and a deposit wallet converts them upward automatically, so 100 Copper becomes 1 Iron. When a purchase costs more than the coins held, higher-tier coins are broken down to cover it. The exchange rate between tiers defaults to 100 and can be set in coin.toml from 2 to 10000.

Admins open a shop editor with the tshop enable Edit Mode command. Admins can rework a shop's layout: categories can be created, renamed, reordered or removed, and item entries can be added, changed, moved or dropped, each with its own price and currency. A layout can be saved as the server default, and changes apply live without a restart. Players create listings by selecting an item in their inventory and setting a price and currency. Buying a listing deducts coins from the buyer, and cancelling returns the item to the seller's inbox, which also holds items while a player is offline until they claim them. Listings expire after a set period.

A sale deducts 5% tax from the seller's proceeds, with a minimum of 1 coin on prices of 2 or more. Taxed coins are destroyed, which reduces the money supply over time. Display names for currencies are set in name.toml, and the Shop Market screens use them.
