L-Auction 1.19.4 - 26.x | Spigot • Paper • Purpur • Folia

Overview

L-Auction is a high-performance auction house plugin built with 100% asynchronous database operations, zero main-thread blocking, and native Folia multi-threading support. It is designed to handle heavy server loads effortlessly while providing an intuitive trading experience for players.

Features

1. Asynchronous Architecture & Folia Support

• All database read/write queries and cross-server synchronizations run entirely off the main thread.
• Native regional scheduler integration for Folia, Paper, and Purpur.

2. Bulk Sell Chest

• Players can place multiple items or entire inventory contents into a dedicated chest GUI.
• Supports both per-item pricing and automatic total price splitting across items.
• Allows instant currency selection and one-click bulk listing.

3. Reverse Buy Orders

• Players can request specific items by creating buy orders with a set unit price and quantity.
• Other players can fulfill these orders directly from their inventories to receive immediate payment.

4. Anti-Abuse & Fraud Protection

• Continuously calculates rolling market averages for all traded items.
• Detects illicit balance transfers, same-IP alt-account trading, and abnormally high-priced junk listings.
• Provides real-time admin alerts, an in-game inspection GUI (/ah alerts), and file audit logs.

5. Shulker Box Preview

• Right-click any listed Shulker Box to inspect its inner inventory without purchasing.

6. Multi-Currency Support

• Built-in integration for Vault (Economy) and PlayerPoints.
• Currencies can be dynamically chosen per listing.

7. Escrow Collection System

• Purchased items, expired listings, cancelled orders, and offline sales earnings are held in a secure escrow GUI (/ah escrow).
• Items are delivered safely to players even when their main inventory is full.

8. Comprehensive Logging & Security

• Detailed transaction logs stored in database and log files.
• Anti-duplication checks on every transaction and cancel operation.
• Built-in market freeze command (/ah freeze on/off) for emergency maintenance.

9. One-Click Legacy Migration

• Direct data importer for AuctionHouse, AkarianAuctionHouse, and zAuctionHouse (/ah convert).
