A structured path for building a Cold Wallet Audit Board your teammates can reopen without you in the room.
Learning outcomes
- Draft a board with separate columns for facts, inferences, and open questions
- Document dual-control steps so witnesses can confirm what they saw
- Phrase firmware and packaging notes without overstating certainty
- Run a short retrospective after a sealed session

Modules
Each module ends with a board artifact you can reuse.
1. Board anatomy
Columns that survive personnel changes; anti-patterns from overloaded spreadsheets.
2. Seed custody language
How to record handling events without pasting secrets into the board.
3. Device inspection notes
Physical checks, packaging anomalies, and photo protocol etiquette.
4. Dual-control drills
Role rotation scripts for operator and witness pairs.
5. Firmware-diff phrasing
Writing verified vs assumed when tooling is incomplete.
6. Retrospective & reopen
Closing a cycle and scheduling the next sealed window.

FAQ
Do you cover every hardware brand?
No. We stay device-agnostic on purpose. You will still need vendor docs for menu paths specific to your units — that is a real limitation of this course.
Will this tell us how to invest?
No. Devlink Core teaches review documentation only. See Not Financial Advice.
Can we cancel?
Eligibility depends on timing — review the Refund Policy before enrolling.

Clear board templates. Took us one extra week to localize column names into Korean.
