HeartGuard — Anti-Dupe & Heart Integrity for Lifesteal
Stop heart duping on your Lifesteal server — without false-banning your players.
HeartGuard recognizes your server's real hearts, gives each one an unforgeable
signature and serial, and removes forged or duplicated hearts before they wreck
your economy. Built to run alongside your Lifesteal plugin (verified with
LifeStealZ), with a safety-first "dry-run" mode so you can turn it on without
fear of hitting legitimate players.
Features
- Heart forgery protection (unforgeable PDC signature)
- Duplicate detection (unique serial per heart)
- Recognizes YOUR hearts via config (LifeStealZ preset included)
- False-positive-safe: dry-run, per-world disable, bypass permission, whitelist
- Audit log of every detection
- Performance-conscious: no world-wide container polling
Not a general anti-cheat/anti-crash — focused on Lifesteal heart dupe/forgery.
Commands
