Lazarus Protocol

Lazarus Protocol — Estate Planning & Emergency Continuity

HellBound & Nyxor

The Lazarus Protocol monitors wallet activity and can notify designated beneficiaries if the user becomes unreachable for a defined period ranging from 30 to 365 days.


How It Works

When Lazarus is configured, XColdPro registers a background watchdog process with the operating system:

  • Windows: Task Scheduler
  • macOS: LaunchAgent
  • Linux: crontab

The watchdog runs automatically every 6 hours, even when XColdPro is not open. During each check, it reads the last recorded activity timestamp and compares it against the configured inactivity threshold.


Five-Stage Escalation

Stage Trigger Action
1 — Reminder 30 days before timeout Sends a reminder to the user
2 — Warning 7 days before timeout Sends an urgent warning to the user
3 — Notify At timeout Notifies designated beneficiaries
4 — Recovery 7 days after trigger Delivers recovery instructions
5 — Final Notice 30 days after trigger Directs beneficiaries to act on recovery instructions

Each time XColdPro is opened, the activity timestamp is updated and all escalation stages are reset.


Security Architecture

NEVER Transmitted Transmitted When Triggered
Seed phrases / mnemonic words Beneficiary name & relationship
Private keys Wallet owner's name (from Gmail)
Wallet passwords Inactivity duration
Full wallet addresses Custom recovery instructions (written by you)
Blackhole encryption keys Attorney/executor contact info (if configured)
Internal system paths Portfolio snapshot: networks, masked addresses, balances

  • All configuration encrypted at rest using AES-256 with PBKDF2-derived keys
  • Gmail credentials separately encrypted in isolated stealth storage
  • Files use Hidden + System + Read-only attributes — invisible to file browsing
  • Disabling Lazarus automatically removes the scheduled task — fully removable

Quick Reference

Setting Value
Background Check Every 6h (OS scheduler) + every 60s (app open)
Timeout Options 1 min (test), 30, 60, 90, 180, 365 days
Admin Required No — runs at user level
Platforms Windows 10/11, macOS, Linux
Email Method Gmail OAuth 2.0 API + Resend (redundant delivery channels)

For best results, use a moderate timeout period (30–90 days). Combine Lazarus with SeedVault Shamir shares distributed to trusted individuals and/or an attorney for maximum estate continuity.
