Sigma Orders & Auctions is a modern, high-performance Minecraft plugin for Paper/Spigot/Folia servers that provides two fully integrated marketplace systems: a player-driven Orders board and a classic Auction House — both powered by the same economy, database, and admin tooling.
Two Marketplaces, One Plugin
| System | What It Does |
|---|
| Orders | Players post "buy requests" specifying an item, quantity, and price. Other players browse these requests, deliver the items, and receive payment through a secure escrow system. |
| Auction House | Players list items for sale at a fixed price with a time limit. Buyers browse listings and purchase instantly. Earnings are credited automatically or held for collection. |
Each system can be enabled or disabled independently via the module toggles in config.yml.
Key Features
- Player-Driven Economy — Players create demand; others fulfill it for profit
- Auction House — Classic timed listings with categories, sorting, and search
- Secure Escrow — Payments are held safely until delivery is confirmed; automatic refunds on cancellation or expiry
- Partial Deliveries — Multiple players can contribute to a single large order
- Multi-Currency Support — Vault, CoinsEngine, and PlayerPoints currencies
- Custom Item Support — ItemsAdder, Oraxen, Nexo, and MMOItems integrated natively
- Modern GUI — Clean, paginated interfaces built with InventoryFramework
- Thread-Safe / Folia — All database and scheduler operations are async-safe
- Discord Webhooks — Automatic embed notifications for both orders and auction events
