Voices From Recent Sessions
They found that my second backup copy was stored in a folder with a different BIP39 word count than my primary sheet. I would never have noticed on my own — the handwriting looked identical at a glance.— Min-jun K., Annual Custody Review, Mapo-gu · March 2025
The session ran longer than expected because we had to locate a passphrase hint my spouse wrote down in 2021. Thorough work, though the office parking was tight on a weekday morning.— Hye-jin L., Recovery Checkup Planning, Seongnam · January 2025
I appreciated that they never asked me to say my words aloud. I typed them into my Ledger myself while they checked the process against their checklist. Felt respectful of the sensitivity involved.— David R., Seed Phrase Audit, Yongsan-gu · November 2024
Our family office holds assets across three hardware wallets. The multisig review took two sessions, which cost more than I initially expected, but the custody log now makes sense to our compliance officer.— Eun-ji S., Multisig Review, Gangnam-gu · August 2024
Extended Account: The Relocated Backup
Client: Couple, mid-40s, relocated from Busan to Seoul in 2023
Service: Annual Custody Review
Challenge: Primary metal backup remained in a Busan safety deposit box; secondary paper copy moved to a Seoul home safe.
During the review, we discovered the Busan copy had not been inspected since 2021. The couple assumed the metal plate was fine because stainless steel “does not rust.” Inspection revealed pitting near the mounting holes — likely from humidity in the deposit box area.
We documented the condition, recommended re-stamping affected words, and updated their custody log with a six-month re-check date. The couple scheduled a follow-up audit after receiving a replacement plate from their manufacturer.
Outcome: Both backup locations now appear in the custody log with verification dates, condition notes, and a shared recovery instruction sheet their adult daughter could follow if needed.
