Envel's Guardian AntiExploit v1.0

Enterprise-Grade Anti-Dupe, Anti-Lag, and Anti-Exploit Security System for Paper, Purpur, and Folia​

Platform Compatibility & Environment Stack​

​

LOOK AT ALL THESE SETTINGS... BUT IT WORKS OUT OF THE BOX!​

Killer Features (That Actually Matter)​

Unyielding Dupe & Exploit Prevention​

• Anti-Dupe Engine: Instant, hard-coded blocking of vanilla dupe machines (TNT, Rails, Carpet duplicators using pistons/slime/coral).
• TNT Minecart Ban: Completely disables TNT minecarts—the number one tool used by griefers to instantly crash or lag out regions.
• Illegal Item Auto-Fixer: Automatically sanitizes oversized NBT data (up to 60k chars to prevent Chunk Bans), strips illegal enchantments, fixes overstacked items (like 64 swords), and enforces a maximum container nesting depth of 4 (bye-bye, crash shulkers).
• World & Portal Hardening: Blocks bedrock and end portal destruction. Plus, a mandatory 1-second Nether portal cooldown prevents player movement glitching.

TPS-Aware Performance Shield & Dynamic Lag-Machine Cleanup​

• Smart Chunk Trash-Sweeper: When a chunk hits the 600-dropped-items limit, Guardian triggers an intelligent cleanup that vaporizes actual trash (cobblestone, netherrack, dirt, seeds) while keeping valuable player loot 100% untouched.
• Redstone & Tile Restraints: Hard caps armor stands (15/chunk), blocks pistons from moving them, limits falling blocks (30/chunk), and throttles explosive redstone updates to 500/second per chunk.
• Adaptive Fire Throttling: If the server drops below 18.0 TPS, Guardian automatically chokes fire spread rates and caps fire blocks to conserve vital CPU cycles.
• Raid Farm Nerf: Prevents economy inflation by hard-capping Totem of Undying drops per hour (12 per chunk / 24 per player).

​

Folia-Native Async Packet & Network Flood Management​

• Per-Event Packet Limits: Individually tracks and flags/drops specific client event overloads (Animations, Placement, Digging, Inventory Clicks) before they lag the main thread.
• Smart Floating VL Decay: Lagging players decay naturally without false kicks, but malicious flooders hit the Max VL wall and get kicked instantly.
• Anti-Crash Input Sanitization: Intercepts and blocks malicious JSON component keywords (translate, with, extra), filters suspicious tab-complete characters ([, ], {, }, nbt), and blocks known WorldEdit injection strings (//calc, /pex, etc.).

​

Ultra-Safe Background Mob Limiter​

• Resource-Friendly Scans: Runs lightweight background passes every 10 minutes to verify entity counts against generous, survival-friendly limits (e.g., 32 Cows, 24 Villagers).
• Survival Exceptions: Named entities (via Name Tags), tamed pets (cats, dogs, horses), and world bosses (Wither, Warden, Ender Dragon) are strictly isolated and completely preserved.
• 1-Block Entity Cramming: Enforces a tight 5-entity limit per single block to instantly neutralize compact entity-cramming lag machines.

​

Gameplay Balance & Anti-Cheat Addons​

• Exploit Rate Limiters: Hard caps inventory click rates (60/sec), container open delays (100ms), and places a strict limit on block placement rates (100/sec) with built-in smart detection that alerts staff.
• Position Sanity Check: Instantly rubberbands players exceeding legitimate speeds (0.7 per tick), blocks illegal land-boats, and kicks anyone trying to exploit coordinates outside the world border.
• Farming Exploits Nerf: Limits Piglin automated bartering loops (max 10/min) and AFK Fishing clickers (max 8 items/min) to keep your economy clean.
• Dynamic Per-Player Localization (i18n): Automatically translates all action bars, titles, and system alerts into the player's native client language.
  

Enhanced Package Customization & Support​

• 10 Hours of Dedicated Engineering: Use these hours for custom feature requests, API expansions, or deep integrations with your existing server core.
• Feature & Cosmetic Customization: We will tweak, optimize, and modify the plugin codebase or visuals to fit your unique setup and implement absolutely all your custom feature wishes.
• Full Installation & Setup: Our team will manually deploy, configure, and stress-test the software directly on your backend servers or proxy network to guarantee a flawless launch.
• 1-Year Premium Priority Support: Bypass the standard ticket queue with direct access to lead developers for immediate troubleshooting and emergency hotfixes.

Clean Engineering — No Strings Attached​

• No DRM / No License Verification: Guardian operates completely isolated. It will never ping third-party verification servers, check external tokens, or call home. Your infrastructure remains 100% autonomous and secure, even in completely air-gapped networks.
• No Code Obfuscation: The production artifact contains clean, readable bytecode. Your systems administration team can freely audit the JAR file to guarantee network compliance and security standards.
• No Artificial Limits: Zero player allocation ceilings, zero instance software blocks. Deploy it freely across your internal developer instances, staging setups, and production networks under a single purchase.

Production-Ready Launch Release & SLA​

• Rock-Solid Stability: Despite the launch release label, the codebase is fully optimized, hardened against real-world production stress, and completely safe for immediate high-traffic deployment.
• Ultra-Fast Support (SLA): If you encounter any edge-case bug, configuration conflict, or anomaly, it will be prioritized and fixed incredibly fast upon your first report in our support channels.
