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

“Module 3’s discrepancy language stopped our team from blaming ‘the market’ when a feed lagged.”

I wanted deeper multisig failure trees. Still kept the export naming rules from Ops Studio.
