Labelling Cold Devices Without Exposing Seeds
A practical guide to naming hardware wallets and steel backups so your rebalancing record stays readable without revealing secrets.
Ulsan · Since 2019
Your cold wallets deserve a written record
Systemhemlock compiles annual rebalancing records for holders who manage hardware wallets and paper backups by hand — no exchange logins, no custodial accounts.
What we document
Annual rebalancing for offline holdings
Each engagement produces a dated, signed record of allocation targets, actual holdings across cold devices, and the adjustments you executed during the year.
Opening snapshot
We photograph your allocation worksheet, list each device by label (never seed phrases), and note target weights before any trades.
Drift reconciliation
Optional quarterly review comparing your handwritten trade log against current cold-wallet balances you verify on-site.
Signed annual record
A bound folder with trade chronology, rebalancing rationale, and allocation charts suitable for your own tax preparer or estate planner.
Flagship consultation
Annual Rebalancing Record Session
For holders with three or more cold devices who rebalance once or twice a year without touching an exchange interface. We meet at our Ulsan office or by secure video while you read balances from your own screens.
Includes a four-hour working session, printed allocation charts, and a tamper-evident bound record delivered within ten business days.

What holders say after their record session
My three Ledger units and one steel backup finally appear on a single timeline. The annual folder sits next to my property deeds — exactly where it belongs.— H.J. Park, Ulsan · Annual record, 2025
The session ran long because I had forgotten two small rebalance trades from March. They caught the gap without making me feel careless — though I wish I'd booked the mid-year check they suggested.— S.M. Choi, Busan · Annual record, 2024
