The "It's reproducible forever, Laura" Release Latest
Latest

SeedSigner v0.7.0

This release is a massive step forward for SeedSigner and had the largest number of dev contributors, ever!

Huge thanks to our volunteer Project Manager: @bitcoinprecept

Highlights:

  • Reproducible builds: don't trust, verify! You can now confirm for yourself that our release images exactly match our FOSS repos.

  • Faster Startup: SeedSigner now starts in only 12 seconds (reduced by ~66%).

  • Faster live camera display: improved framerate makes aiming the camera a much smoother experience.

  • QR-based message signing: Compatible with Specter Desktop (or any QR code generator/reader app).

  • SettingsQR Generator: create settings configs that you can instantly scan in to transform your SeedSigner experience. e.g. create a stripped-down, basic noob config that simplifies SeedSigner for demoing to friends but have an advanced expert config for yourself.

  • More responsive controls and clicks (50% to 100% faster).

  • On-screen hint for adjusting the QR code display brightness: the primary solution for dealing with low quality webcams.

  • MicroSD removal hint: gentle reminder for the most careful/paranoid security maxis that you can remove the SD card before loading a seed.

  • Screenshot generator: We can now generate pixel-perfect screenshots of most screens in the UI. Ideal for including in tutorials, etc.

  • Flow-based tests: the test suite now includes end-to-end, screen-by-screen scenario tests (e.g. user loads a seed, then scans a psbt, etc). This is a massive improvement for regression testing (does a change break any existing functionality?) and debugging any user-reported errors.

Notable Camera Change:

Camera orientation: default was 0°, now 180°.

SeedSigner builds have evolved to favor the mini Raspberry Pi camera (no daughterboard; components integrated into the ribbon cable). The new default is for these builds.

If your build uses the bigger camera (has a daughterboard; original "Orange Pill" enclosure), you'll need to set camera orientation to 0° with this release.

Notes:

Image Designations:

Four .img files are included in the release; select the one that is appropriate for your Raspberry Pi hardware:

  • "pi0.img" - For Raspberry Pi Zero v1.3 & Raspberry Pi Zero W
  • "pi2.img" - For Raspberry Pi 2 Model B
  • "pi02w.img" - For Raspberry Pi Zero 2 W & Raspberry Pi 3 Model B
  • "pi4.img" - For Raspberry Pi 4 Model B

Checking your download for integrity and authenticity is super important -- with SeedSigner, you are the software authenticity assurance!

To install on your microSD card:

  • Download the appropriate .img file
  • Write the extracted image to a MicroSD card (32MB or larger)
  • (make sure to use "dd" or a disk-authoring tool like Balena Etcher)
  • Re-install the memory card in your signer

Pre-release

SeedSigner v0.7.0-rc1

This release will be a massive step forward for SeedSigner but we need your help with testing first! Please download and bang around on the released images, and also please get in touch if you would like to help with more formalized testing. Help us find and smoosh those bugs!

Highlights

  • Reproducible builds: don't trust, verify! You can now confirm for yourself that our release images exactly match our FOSS repos
  • Now boots in 12 seconds (reduced by ~66%)
  • QR-based message signing. Compatible with Specter Desktop (or any QR code generator/reader app)
  • Full SettingsQR support. Create a variety of safe-to-print settings configurations with the SettingsQR Generator and instantly load them in as needed -- see: https://seedsigner.github.io/seedsigner-settings-generator
  • More responsive controls
  • Faster live preview framerate. No more slow, choppy live previews while trying to aim your SeedSigner camera
  • Screenshot generator. We can now generate pixel-perfect screenshots of most screens in the UI. Ideal for tutorials, etc. see: https://github.com/SeedSigner/seedsigner-screenshots/blob/main/en/README.md
  • Brightness adjustment tip: solve problems with terrible webcams by adjusting the brightness when displaying a QR code on the SeedSigner screen
  • MicroSD removal reminder: gentle reminder for the most careful/paranoid security maxis that you can remove the SD card once the boot process is complete

Four .img files are included in the release; select the one that is appropriate for your Raspberry Pi hardware:

  • "pi0.img" - For Raspberry Pi Zero v1.3 & Raspberry Pi Zero W
  • "pi2.img" - For Raspberry Pi 2 Model B
  • "pi02w.img" - For Raspberry Pi Zero 2 W & Raspberry Pi 3 Model B

The "Two More Weeks™" Release

This release has been a long time in the making... But it's been worth the wait.

New Features:

  • SeedSigner OS (custom Linux operating system)
    • Remove microSD after start-up
    • Networking/BT/swap/usb removed from kernel
    • Deployment image is ~100x smaller
    • Build from scratch with minimal commands
  • Single/multisig receive/change address explorer
  • BIP-85 deterministic seed derivation
  • Support for p2tr (taproot) signing
  • Compact SeedQR now enabled by default
  • More responsive QR dismissal
  • MicroSD removal & reinsertion notification
  • Keeper coordinator option added (disabled by default)
  • Various other UI tweaks & minor bugfixes

Special Note:

Four .img files are included in the release; select the one that is appropriate for your Raspberry Pi hardware:

  • "pi0.img" - For Raspberry Pi Zero v1.3 & Raspberry Pi Zero W
  • "pi2.img" - For Raspberry Pi 2 Model B
  • "pi02w.img" - For Raspberry Pi Zero 2 W & Raspberry Pi 3 Model B
  • "pi4.img" - For Raspberry Pi 4 Model B

Checking your download for integrity and authenticity is super important! We'll need to update our instructions, but the same basic process outlined in the ReadMe at the root of the repo will work to verify the released signature file and operating images.

More Notes:

To install on your MicroSD card:

  • Download the appropriate .img file
  • Write the extracted image to a MicroSD card (64MB or larger)
  • (make sure to use "dd" or a disk-authoring tool like Balena Etcher)
  • Re-install the memory card in your signer
  • 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
  • Built for compatibility with Nunchuk 1.9.7 and up
  • Rotate the screen, adjust brightness (up/down) & reduce QR density to resolve glare/lighting issues
  • Scan a Bitcoin address to initiate the manual verification process
  • The best way to practice & get comfortable with signing is testnet/regnet
  • Test with small amounts of BTC first if starting with mainnet
  • You are the software integrity assurance mechanism -- verify your downloads!

The "Look Ma, no MicroSD!" Experimental Release Pre-release
Pre-release

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

If you are getting value from SeedSigner, please consider donating to our development fund: https://seedsigner.com/donate-now/

For anyone testing with this experimental release, please make any suggestions and report any bugs in our Telegram group!
