This experimental release features a new customized Linux Buildroot operating system that we're calling "SeedSigner OS".

More information on SeedSigner OS can be found at: https://github.com/SeedSigner/seedsigner-os

Over time SeedSigner OS will open up additional possibilities, but this initial release already includes the following features:

  • Dramatically smaller binary release image (~3.8 GB ==> ~0.035 GB)
  • Ability to remove (and re-insert) the memory card after boot
  • Reduced attack surface due to customized, security-hardened OS

It should also be noted that this release can be built from scratch with just three terminal commands.

Because this release is experimental and not recommended for use with real funds, no G/PGP attestation signature is being provided with the released files.

Known Issue: This experimental release is not compatible with Pi Zero 2W

To install on your MicroSD card:

  • Download the file "SeedSignerOS_0_5_1_EXP.img"
  • Write the extracted image to a 64 MB or larger MicroSD card
  • (make sure to use "dd" or a disk-authoring tool like Balena Etcher)
  • The UI should appear in less than a minute after applying power to the device

General SeedSigner Considerations:

  • Built for compatibility with Specter v1.4.5 and up
  • Built for compatibility with Sparrow Wallet v1.4.2 and up
  • Built for compatibility with BlueWallet v6.1.9 and up
  • Use up/down to adjust brightness while QRs are displayed
  • Scan a Bitcoin address to initiate the verification process
  • The best way to practice & get comfortable with signing is testnet
  • Test with small amounts of BTC first if starting with mainnet
  • Rotate the screen, adjust brightness (up/down) & reduce QR density to resolve glare / lighting issues
  • You are the software integrity assurance mechanism; verify your downloads!
