SeedSigner v0.8.0

It's admittedly been a minute since our last release -- we've always built carefully and deliberately, and we continue to refine our software so bitcoiners everywhere can have a better and better permissionless signing device.

Quick Highlights:

Addtional legacy signing support:

  • P2PKH (bip44): Legacy format dating back to 2014
  • P2SH multisig (bip45): Legacy multisig (also 2014)

Quality-of-Life improvements ❤️

  • New animated QR scanning UI + frame-by-frame feedback
  • Much better animated QR scanning progress estimation calcs: no more stuck-at-99%-progress misery!
  • Smarter rendering of outgoing animated QRs = faster reads by wallet software
  • UX improvements when entering bip39 passphrases, verifying multisig change, etc.
  • Two new community-created 3d-printable enclosure designs

Explicit support for PSBTs w/OP_RETURN

  • displays the human-readable message or the raw hex data

Import Electrum Seeds 🌱

  • Import an Electrum native segwit mnemonic, export xpub, sign txs.

Major code refactors, Github automations, MOAR TESTS🔥!

  • Crucial yet unwieldy code got much more wieldy
  • Awesome Github Actions integrations to automate test suite checks & generate custom SeedSigner OS images
  • Significant upgrades to the test suite, both under the hood & overall test coverage

Notes:

Legacy multisig support enables full SeedSigner compatibility with Unchained vaults! (this is unofficial; don't expect Unchained customer support to be able to help you)

The new animated QR scanning UI is sexy (@easyuxd ftw!) and adds a green/gray feedback dot:

  • Green = QR frame read, new data received
  • Gray = QR frame read, but no new data
  • No dot = wtf are you pointing at?

New Pro Tip: If your software coordinator seems stalled when reading a long outgoing animated QR, flick the SeedSigner joystick up/down. Why? The first few frames of an animated QR are the most valuable and they do NOT repeat. But now when you change your SeedSigner's outgoing QR code brightness (joystick up/down), those valuable frames are re-played.

Adding limited support for Electrum seeds is meant to help legacy/OG users eventually migrate away from Electrum and into more standardized wallet software. Full integration with Electrum is not planned.

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

  • You are the software integrity assurance mechanism -- verify your downloads!

The "Look Ma, no MicroSD!" Experimental Release

Choose a tag to compare

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!
