Why paper for cold storage

Hardware wallets and air-gapped machines protect keys at rest. They do not, by themselves, tell your family which device holds which wallet, what passphrase variant you used in 2021, or where the spare steel plate sits in your filing cabinet.

Our record books are structured ledgers—not generic notebooks. Each section prompts you for wallet labels, backup locations, verification dates, and heir contact steps without leaving blank pages that invite inconsistent notation.

Clients typically complete their first draft during a 90-minute documentation session at our Busan office or via guided remote appointment.

From recent client conversations

I had three Trezor backups scattered across two cities and a safe deposit box. The record book forced me to write down which label matched which passphrase hint. My wife can follow the heir section without calling me at 2 a.m.

The binding quality is excellent and the acid-free paper feels substantial. I wish the consultation had covered multisig notation more deeply—that part I still annotated by hand in the margins.

— Helena R., family office administrator, Busan
