Before, During & After Sessions
Before Every Session
- Verify air-gap: Disconnect WiFi and ethernet before launching XColdPro
- Check USB drive: Inspect for physical tampering, and confirm the drive mounts with the same drive letter and volume label used when the vault was bound
- Confirm environment: Ensure no one is watching your screen or can see your password entry
- Verify integrity: SentinelGuard runs automatic file integrity checks on launch
During Operations
- Verify addresses: Always compare first and last 6 characters on both devices
- Check transaction details: Amount, destination, network fees — verify everything before signing
- Use Visual Fingerprinting: Match the visual pattern between sending and signing devices
- One operation at a time: Complete each transaction before starting another
- Watch for warnings: SentinelGuard alerts require immediate attention — do not dismiss
After Every Session
- Properly close XColdPro: Use the application's exit function (triggers automatic EMBO memory wipe)
- Safely eject USB: Always use "Safely Remove Hardware" — prevents data corruption
- Secure storage: Store USB drive in safe, locked location when not in use
- Disconnect completely: Remove USB from computer — physical air-gap restored
Ongoing Maintenance
- Check seed phrase backups annually — verify paper is legible, ink hasn't faded
- Test recovery procedure — periodically restore from seed on a separate USB drive
- Update XColdPro — install updates from official portal when available
- Monitor USB drive health — replace drives showing wear (3–5 year recommended lifecycle)
- Review beneficiary information — keep Lazarus Protocol beneficiaries, attorney/executor contacts, and recovery instructions current (HellBound/Nyxor)
