Quick start 09 — SeedQR backup

A SeedQR encodes a seed phrase as a QR you can scan back into SeedSigner instantly. There are two formats: Standard (words as decimal numbers) and Compact (hexadecimal). Standard is human-transcribable; Compact is smaller.

Part 1 — Choose the format and transcribe

1. Load the seed and choose Backup seed → Export as SeedQR.

2. Choose the SeedQR format (Standard or Compact) and size.

   Compact SeedQR must be enabled in Settings → Advanced to appear.

3. SeedSigner shows the QR as a grid. Options:
   • Whole QR — show the entire code for a printer or camera.
   • Zoomed in — step through the modules to hand-transcribe onto a printed template.
4. Transcribe carefully using the printable templates:
   • Standard: 12-word = 25×25; 24-word = 29×29.
   • Compact: 12-word = 21×21; 24-word = 25×25.

   Templates live in Seed QR printable templates and are described in the Seed QR README.

Part 2 — Verify the SeedQR

SeedSigner can scan the SeedQR back and confirm it decodes to the same seed. Use Seed Transcribe → Confirm from the flow to scan your handwritten code before trusting it as a backup.

Part 3 — Load from a SeedQR

1. Seeds → Load a seed → Scan a SeedQR (or Scan a seed).
2. Point the camera at the SeedQR.
3. SeedSigner loads the seed and shows its fingerprint.

SeedQRs are plaintext. Store them like you would the written words — preferably somewhere offline and protected.
