Shipping

Orders are built and shipped in small batches, typically within 3-5 business days of purchase. Assembled items (like a pre-assembled SeedSigner or a built ClockChain) may take a little longer than unassembled kits or small accessories, since each unit is bench-tested before it goes out.

You'll receive a shipping confirmation by email once your order is on its way. Domestic and international shipping options and costs are calculated at checkout based on package weight and destination.

  • Unassembled kits and 3D-printed accessories: usually ship within 1-3 business days.
  • Pre-assembled & tested devices: usually ship within 3-5 business days.
  • Tracking is provided on every order.

The SeedSigner Workshop is a service, not a physical product — nothing is shipped. After booking, you'll get an email to schedule the remote call or agree on a time and location for an in-person session.

Customs & Duties

For international orders, any customs fees, import duties, or taxes charged by your country are the buyer's responsibility and aren't included in the checkout total.

Returns & Refunds

If something arrives damaged or doesn't match what was ordered, contact us within 14 days of delivery and we'll sort out a replacement or refund.

For change-of-mind returns: unopened, unassembled kits and unused accessories can be returned within 14 days of delivery for a refund of the item price (shipping costs are non-refundable). Because of the nature of the product, we can't accept returns on devices that have already been flashed with firmware or otherwise put into use — this protects both you and future buyers, since we have no way to verify the security of a device's history once it's left our hands.

To start a return, reach out via the contact page with your order details.

A Note on Trust

None of this replaces doing your own diligence. Before trusting any signing device with real funds — ours or anyone else's — verify the firmware yourself. See how to verify your device for the specifics.
