Testimonials

The Daegu office visit took ninety minutes. Dae-won walked us through every line of the bound log before we left. Our accountant asked for exactly this kind of dated inventory—not a wallet screenshot.
— Eun-kyung Lim, small business treasurer, Daegu
We keep three Ledgers in a bank vault box in Incheon. Content Birchfield met us at the branch, waited through the access procedure without complaint, and noted the vault hour restrictions in the log margin. That detail mattered when our auditor read it.
— James Walsh, family office administrator, Incheon
I wished they had arrived earlier in the day—the bank vault closed sooner than expected and we used an extra hour. The invoice matched the quote addendum they sent mid-visit. Transparent, if not cheap.
— Tae-ho Yoon, private holder, Gwangju
Quarterly retainer visits are quiet and methodical. Soo-jin compares seal photos from the last entry before opening anything. Our trustees in Busan receive the appended pages by courier within a week.
— Hye-rim Seo, estate coordinator, Busan

Case Note: Gangnam Trust Review

A Seoul family trust held two Trezor Model T units and one Coldcard in a floor safe. Counsel requested proof that devices had not been accessed since a 2024 succession memo. We scheduled an on-site visit, photographed intact tamper seals, ran offline balance checks, and produced a log with witness signatures from both trustees present. The solicitor accepted the folio without requesting a second opinion. Total on-site time: two hours and twenty minutes.

Case Note: Daegu Office Archive

A manufacturing firm kept a single Ledger Nano X in an office strongroom for director-approved reserves. They chose the Reserve Log Documentation package after performing monthly offline checks internally. We corrected twelve entries missing firmware versions, bound the volume, and registered it to the company name. The firm now adds witnessed pages quarterly under retainer.
