Handwritten Backup Reconciliation

Line-by-line comparison of your paper recovery phrases against stamped steel, laminated cards, or bound ledgers in a private, air-gapped room.

Handwritten Backup Reconciliation

Who this session serves

Families, trustees, and independent holders who maintain recovery phrases on paper while storing the authoritative copy on stamped steel or engraved plates. The session is for custodians who want a second pair of eyes before locking materials away for years.

What you receive

A reconciler reads each word aloud from your paper backup while you follow along on the metal original. Discrepancies — transposed letters, duplicated lines, omitted words, or BIP-39 checksum failures — are marked on a session worksheet. You leave with a tamper-evident report sealed in an envelope; we retain no copies of your phrase material.

  • Pre-session intake call (15 minutes) to confirm artifact types and word count
  • Private reconciliation room with no cameras, no Wi-Fi, and no personal devices permitted
  • Two-pass read-aloud protocol with a mandatory break between passes
  • Discrepancy log with line references and suggested correction steps
  • Post-session checklist for re-sealing storage containers

What is excluded

  • We do not engrave, stamp, or manufacture backup media
  • We do not photograph or digitize recovery phrases
  • We do not provide investment, tax, or legal guidance on asset allocation
  • Rush same-day sessions are not available

Provider
