SeedSigner is an open-source, DIY Bitcoin hardware wallet that puts you in complete control of your private keys.
Built on affordable, widely-available components, it eliminates dependency on proprietary devices while maintaining enterprise-grade security.



It is stateless by design (it never stores private keys) and functions as a “Swiss Army Knife” of offline Bitcoin tools: key generation, transaction signing, multisig coordination, seed backup, and address verification.

Software setup: Follow our SeedSigner setup guide to choose the correct software, flash the microSD card and start your device. The guide also covers blank-screen troubleshooting.

Included Components:

  • Raspberry Pi Zero v1.3 (without Wi-Fi or Bluetooth)
  • Waveshare 1.3-inch LCD display, 240 × 240 pixels
  • Raspberry Pi Zero-compatible camera
  • 40-pin GPIO header (2 × 20), pre-soldered to the Raspberry Pi
  • PNY 64 GB microSDXC card with SD adapter
  • 3D-printed case (orange)
  • Micro-USB cable
