How It Works

Every valuable item gets a unique fingerprint based on its NBT data. When players move items around, the plugin tracks these fingerprints and catches duplicates before they spread.

Features

  • Unique item fingerprinting with NBT tracking
  • Real-time duplicate detection
  • Packet manipulation protection
  • Shulker box exploit prevention
  • Book/chunk dupe detection
  • Inventory rollback protection
  • Custom item support for plugin items
  • Discord webhook alerts
  • Admin GUI dashboard
  • Transaction history logging

Detection Methods

  • Velocity Tracking: Catches items appearing too fast
  • Cluster Detection: Spots identical items in groups
  • Cross Validation: Verifies item movements match expected behavior
  • Packet Analysis: Detects client manipulation attempts
  • Pattern Recognition: Identifies macro and bot patterns
