Testimonials
I had four Ledgers and a Trezor accumulated over eight years of buying dips. The rotation session sorted them into a ledger I keep with my will. Ji-hoon never asked to see a seed phrase — only serial numbers on the device backs.— Sung-ho L., Mapo-gu, rotation planning session, 2025
Our family office holds cold storage across three family members. The archive setup created a filing system our lawyer could actually follow. The index cards are a bit small for my handwriting, which was annoying, but the structure itself is clear.— Patricia R., Seocho-gu, archive ledger setup, 2024
Annual review caught that I had replaced a Coldcard but forgotten to update the ledger. Worth the two hours. I would have preferred a Saturday slot but weekday scheduling worked eventually.— Daniel M., remote session from Busan, inventory review, 2025
Eun-ji designed a binder system for our retired devices going back to 2016. My spouse can now find any archived unit without calling me. Straightforward service, no unnecessary extras.— Yuri T., Incheon, archive ledger setup, 2023
Extended Account: The Three-Generation Ledger
Client: Grandfather, father, and adult son — each holding separate hardware wallets for a shared family allocation.
Challenge: Three passphrase variants across five devices, with two units already retired but stored in an unmarked box. No written record of which variant matched which device.
Engagement: Two rotation planning sessions (one in person, one remote) plus archive ledger setup over three weeks.
Outcome: A master ledger with colour-coded sections per family member, archive index cards for two retired Ledger Nano S units, and a one-page access instruction sheet sealed for the family’s attorney. The grandfather’s primary concern — that his grandson could locate the correct device after his death — was addressed through the filing system rather than any technical intervention.
Client note: “The sessions felt more like organising a safe deposit box than anything technical. That was exactly what we needed.”
