- Module 2 — Read-only discipline Run timed readouts, timestamp exports, and quarantine anything that smells like a signing workflow.
- Module 3 — Reconciliation tabletop Match Cold Storage Balance Monitor totals to vault logs; practice naming discrepancies without guessing causes.
- Module 4 — Handoff and review Write shift notes a stranger can trust, then peer-review three sample reports.
Learning outcomes

FAQ
Do I need hardware wallets for the drills?
Simulated exports are enough for most exercises. If you use real devices, keep them offline and follow your own policy — the course does not supply keys or devices.
Is this financial advice?
No. Content is educational only. Read our Not Financial Advice page.
What is a real limitation of this course?
We do not certify hardware vendors or guarantee that your Cold Storage Balance Monitor software configuration is correct. Learners still need vendor docs and an internal review for device trust.
Learner notes
I wanted deeper multisig failure trees. Still kept the export naming rules from Ops Studio.
