Intake freeze
Photograph serials, packaging seals, and cable set before power is applied.

Air-Gapped Wallet Review Lab for quieter device intake
Practice how reviewers document offline signing desks, firmware provenance, and air-gap boundaries — without turning education into trading guidance.
Flagship program
Offline Signing Desk Review
A paced lab that walks through intake photography, sealed-bag chain notes, QR/PSBT handling on a cold machine, and a review memo format teams can reuse. Built for security-curious operators and ops leads in Korea and beyond.
How a review desk moves
Four beats we teach so air-gapped wallet reviews stay boring in the best way — predictable, logged, and easy to re-open later.
Boundary map
Name what is online, what is air-gapped, and which media may cross.
Signing rehearsal
Walk a dry-run PSBT path with no funds at risk and note every UI prompt.
Memo close
Write findings in plain language a peer can challenge without drama.

Voices from the lab
Learners reference specific modules — and one notes what still felt unfinished.
The “Boundary map” exercise in Offline Signing Desk Review forced us to stop treating a spare laptop as air-gapped just because it lacked Wi‑Fi drivers. We rewrote our intake sheet the same week.
Firmware provenance checklist was solid. I still wanted more examples for multisig co-signer handoffs.
Short and clear: the QR rehearsal module matched how our Wando desk actually works.
What stays on the desk
Evidence before opinion
Serial photos and seal notes land before anyone debates configuration choices.
Named media paths
SD cards, QR panes, and USB write-blockers get explicit roles so crossings stay intentional.
Memos peers can reopen
Review write-ups favor timestamps and observations over slogans about “security.”
