Vault Fundamentals: Private Key Storage Checklist
Six modules that turn vague “be careful with seeds” advice into labeled backups, device rules, and a recovery rehearsal you can time. Content is educational — Not Financial Advice.
Learning outcomes
- Produce a written storage map covering every key material you control
- Choose hot/warm/cold paths with explicit tradeoffs for your workflow
- Label offline backups so a future verifier can follow without guessing
- Run a timed recovery drill and log gaps for follow-up
- Draft a brief for a trusted contact that avoids sharing the seed itself

Modules
Each module ends with a worksheet uploaded for optional instructor comments.
1. Inventory before advice
List wallets, devices, and who currently knows recovery paths. Catch orphaned accounts early.
2. Storage map & threat notes
Map physical and digital locations. Note realistic threats (theft, roommate access, travel) rather than cinematic ones.
3. Offline backup craft
Paper, steel, and split schemes—with verification steps and anti-photo rules.
4. Device & travel hygiene
Update rituals, packing lists, and what never rides in the same bag as the seed.
5. People & escalation
How to brief a deputy without emailing secrets. Simple escalation when the primary holder is unavailable.
6. Recovery rehearsal
Timed restore of a test wallet. Log misses. Schedule the next verification date.

FAQ
Do I need a hardware wallet already?
Yes for Modules 4 and 6. We do not sell devices. If you lack one, complete Modules 1–3 first and return for rehearsals later—this is a real limitation of the course design.
Is this financial advice?
No. See Not Financial Advice. We teach storage and recovery hygiene only.
What language are sessions in?
Materials are English. Live office hours are English with occasional Korean clarifications for Korea-based cohorts.
Can teams join together?
Individual seats use Vault Cohort pricing. For facilitated group drills, ask about Team Drill Day on the pricing page.
Learner notes
“Module 6 exposed that our steel backup was missing two words. Uncomfortable, but better in a drill.”
“Clear worksheets. I still needed outside help setting up multi-sig—the course stays honest that it does not cover that stack.”
