The Endex 1.5.3 | Dynamic Market & Addons [1.20.1 - 1.21.x]

Bring a living economy to your server. Prices move with player demand and supply, with a slick Market GUI, timed events, optional web dashboard, virtual holdings system, and an addon framework.

The Endex is a dynamic economy plugin that brings realistic market mechanics to your Minecraft server. Prices fluctuate based on player trading activity, server-wide item storage, and random market events.

🆕 Version 1.5.3 Highlights:

• PlaceholderAPI Support — 30+ placeholders for scoreboards, holograms, and other plugins
• Update Checker — Automatic notifications when new versions are available
• GUI Customization — Full layout, colors, and slot position customization

• Optimized World Scanner — Intelligent chunk caching with dirty tracking

💰 Dynamic Pricing
