Storing Allocation Sheets in Separate Locations

An allocation sheet contains no secret material—only addresses, balances, and derivation path labels. Yet storing it beside your seed phrase backups creates a single point of failure: anyone who finds your safe gets both recovery information and a map of your holdings.

The three-location model

We recommend holders maintain:

1. Seed phrase backups in location A (home safe or bank deposit box)
2. Master allocation sheet in location B (office drawer, trusted family member, second deposit box)
3. Sealed duplicate sheet in location C (different city or separate institution)

Location B should be accessible enough for quarterly reviews. Location C is insurance against fire or theft at location B.

What the sealed duplicate contains

The duplicate is identical to the master. We seal it in a tamper-evident envelope at handover. You sign the envelope flap. If the seal breaks, assume the sheet was read and consider whether address reuse or operational security requires changes—this is an operational decision, not one we advise on.

Updating across locations

When you add an address, update the master first during your review session. Mail or hand-deliver a new sealed duplicate to location C. Do not photocopy the master and leave both copies in one place “temporarily”—temporary becomes permanent.

Domestic travel within South Korea

Holders who travel between Seoul and Daegu sometimes carry a laminated address index card (not the full sheet) for reference. The index card lists address groups without balances. Full sheets remain in fixed locations.

Workshop note

Our allocation sheet workshop includes a 30-minute segment on storage planning. Participants map their own three-location model on paper before leaving.
