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

- 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
