My Trezor Model T had been in a desk drawer since I bought it in 2020. During the hardware inspection, the verifier noticed the screen had a faint vertical line that would have made address confirmation difficult. I replaced the device the following week and re-ran the seed verification at my second appointment.— Hye-jin M., hardware wallet inspection, March 2025
We maintain a 2-of-3 multi-sig for our family trust. Getting all three signers to Daegu on the same afternoon was a logistical headache, and one signer had to join by speakerphone for the documentation portion. The verifier was patient with the arrangement, though I would recommend scheduling a full half-day if your setup is similarly complex.— Robert T., yearly cold wallet verification, January 2025
The seed phrase audit caught that I had written "alien" instead of "align" on word nine. I would never have noticed until a recovery attempt failed. The audit summary is now filed with our household records next to the insurance policies.— Yuna P., seed phrase audit, November 2024
I appreciated that the verifier never rushed me when I hesitated before opening the envelope. The session ran about fifteen minutes over the scheduled time, but there was no extra charge. The follow-up email listing three action items was clearer than I expected from a handwritten report.— Daniel W., yearly cold wallet verification, September 2024
Extended Case Note: Thermal Paper Failure
Client: Expatriate resident of Daegu, holding since 2018 Service: Seed phrase audit (initial visit) followed by yearly verification six months later
The client arrived with a seed phrase printed on receipt paper from a convenience store printer in 2018. Under normal office lighting, nine of the twenty-four words were partially illegible. The verifier photographed the paper density pattern (not the words themselves) to document fading severity and recommended re-inscription on archival paper.
At the follow-up session, the client returned with a new backup inscribed on acid-free cardstock and stored in a fire-resistant envelope. The audit confirmed all words legible. The client noted that the process took longer than anticipated because they had to coordinate a quiet evening at home to generate the new backup without interruption.
Outcome: Legible backup confirmed. Prior thermal paper destroyed by client at home. Verification report filed for personal records.
Extended Case Note: Passphrase Forgotten, Seed Intact
Client: Local business owner, single-sig Ledger Nano S Service: Yearly cold wallet verification
During the passphrase discussion, the client realised they could not recall the exact word they had added as a BIP-39 passphrase in 2022. The seed phrase itself was intact and legible. The verifier documented the situation, explained the implications, and recommended the client attempt passphrase recovery at home using their own notes before considering any wallet migration.
The client returned three weeks later having recovered the passphrase from a notebook they had forgotten about. The second portion of the verification was completed without additional charge for the follow-up discussion (under 20 minutes by phone).
Outcome: Passphrase recovered by client. Full verification report issued. Client enrolled in annual reminder programme.
