UCExchange

UCExchange is a daily rotating trade market plugin for Paper servers.

It allows players to exchange common resources for money or rarer items through a simple and clean GUI. The available offers rotate automatically every 24 hours, helping the market stay fresh and giving players a reason to come back regularly.

The plugin is made for survival, economy, and public servers that want a dynamic market system without relying on a full shop plugin. Everything is configurable, including menu settings, available trades, messages, refresh behavior, Discord webhook logs, and update checking.

UCExchange also includes built-in support for PlaceholderAPI, making it easy to display market information in scoreboards, holograms, menus, tablists, and other compatible plugins.
