I am seeing much higher order volume than usual after the recent Coldcard bug. Some orders will be delayed. For SeedSigners, expect a lead time of about two weeks.

I do not sell a signing device to someone I have not spoken to.

Every signing device sold here includes a session with me. Written or live, arranged once your device has arrived.

Every signing device here includes a session with me. We arrange it once your device has arrived. What we cover is up to you.

An hour with me is €300. With a device it is €150.

What it covers

  1. Step-by-step walkthrough. Setup and proper usage of your new hardware.
  2. Verification process. Making sure your hardware is tamper-free and secure.
  3. Risk analysis. Common mistakes, and how to avoid them.
  4. Backup review. Help with a proper backup and a recovery you have actually tested.

Written over email or chat, or a live private call. You choose which when we book, not when you buy. No KYC data is required at any point, when ordering or during the session itself.

Booking

Your order confirmation carries the booking link. Sessions are arranged after your device has arrived, so you have it in your hands while we work.

Orders under €150

Backup steel, cards and small parts are pieces of a setup rather than products on their own, so they go out with an order of €150 or more.
