AntiDupeX - Anti-Duplication System 🛡️
AntiDupeX is a powerful and lightweight utility script/addon designed to secure your Minecraft server economy by completely preventing item duplication exploits.
🔥 Key Features
Bundle Exploits Protection: Blocks known duplication glitches associated with Minecraft bundles and inventory manipulation.
Lightweight & Fast: Optimized performance using Script API (main.js) without causing server lag or TPS drops.
Plug & Play: Easy installation with zero complex setup required—just import and protect your realm or server instantly!
🛠️ How It Works
AntiDupeX continuously monitors item transfers and inventory interactions. When a player attempts to execute a known duplication method (such as manipulating bundle states or rapid item drops), the system detects the anomaly, cancels the action, and keeps your server fair and clean.
