Rotation Planning for Long-Term Holders

Hardware wallets age. Firmware updates arrive. Backup copies multiply. Without a written rotation schedule, holders discover gaps only when a device fails or a family member needs access instructions.

We sit with you — in person at our Songpa office or over a secured video call — to map every device, its firmware version, its backup location, and the date it should be retired or replaced. The output is a paper rotation ledger you keep, not a cloud account we control.

What Holders Say

After our third Ledger purchase I had no idea which device held which passphrase variant. The rotation session produced a ledger I laminated and filed with my attorney. Took half a day, saved me years of confusion.
— Min-jun K., Seoul, rotation planning session
The archive setup was thorough. I wish they had included a second copy of the index cards in the initial package — I had to request that separately — but the filing system itself is solid.
— Hana S., Bundang, archive ledger setup
