Who this is for

Individuals and families who store cryptocurrency seed phrases on paper cards, laminated sheets, or engraved steel plates and want a durable, tamper-evident record of where those materials live, who has accessed them, and what condition the seals are in.

What you receive

A hardbound A4 logbook with numbered pages, pre-printed fields for dates and witness initials, and adhesive pockets for seal photographs. We supply numbered tamper-evident tape and a small wax seal kit sized for envelope flaps and capsule lids.

Scope

Included:

  • Inventory of up to three sealed containers at one address
  • Photographs of each seal before and after handling
  • Humidity and temperature notes for the storage area
  • Written chain-of-custody template for future moves
  • Brief instruction on adding entries yourself between visits

Excluded:

  • Recovery of lost phrases or broken hardware
  • Translation of phrase content (we never read seed words)
  • Storage containers or fireproof boxes
  • Bank vault rental fees

Process

  1. Inquiry — You describe backup types and locations via our contact form.
  2. Quote — We confirm scope, travel, and deposit within two business days.
  3. Visit — Min-jun Park arrives with logbook materials. You remain present for all handling.
  4. Binding — Pages are bound on-site; you keep the original. We retain no copies.
  5. Follow-up — Optional reminder to schedule quarterly refreshes.

Timeline

Standard scheduling: 7–10 business days from deposit receipt. Same-week visits occasionally available.

Preparation

Gather all backup containers in one room if possible. Have any existing notes about prior moves ready. Ensure adequate lighting—we bring a portable lamp but desk space helps.
