SeedSigner v0.7.0: Reproducible Builds, Faster Startup & More

“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.””If you are getting value from SeedSigner, please consider donating to our development fund.””Check out our Independent Custody Guide to read more on what our project is all about.”

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.
