SeedMask hardware
A dedicated cold-storage signer for Bitcoin and Kaspa. Built around a 3.5″ touchscreen — stay offline while your Coordinator handles the watch-only workspace.
Bitcoin
Kaspa
Bitcoin & Kaspa — nothing else
SeedMask focuses on two chains so the device can stay sharp: clear confirmation screens, predictable signing flows, and no multi-asset noise.
3.5″ air-gapped display
Unsigned transactions are prepared on the Coordinator. Signatures are produced on SeedMask’s touchscreen. Private material never crosses into the desktop app.
Coming soon
Hardware is in progress. There is no shop checkout yet — when we open orders, this page will be the first place you hear it.
