This release is all about making it quicker and easier to import your seed phrases!

To install on a MicroSD, download the file "seedsigner_0_4_2.zip", extract the .img file, and write that image to a MicroSD card (at least 4GB in size).

Startup time is holding for now at ~50 seconds. (Way down from where we started at 90 seconds!)

(Please note that our core air-gapped QR signing functionality is working reliably, however when making transactions with numerous inputs [UTXO consolidation] the volume of frames to scan in and out of SeedSigner can be large. We have several paths to optimize this process and will be bringing improvements in future versions of SeedSigner.)

New Features:

  • BIP39 passphrase support (more security for your seeds!)
  • SeedQR transcription UI & import mechanism
  • Single-Signature Wallet Mode (1-of-1 at last!)
  • QR density setting (low/med/high)
  • Extended public key information detail (verify ALL your cosigners!)
  • Enhanced transaction information display
  • Optimized menu structure / workflow

Bug Fix

  • Release includes updated embit 0.4.2 to resolve a fee estimation error when using Sparrow Wallet

Considerations:

  • Built for compatibility with Specter v1.4.5 and up
  • Built for compatibility with Sparrow Wallet 1.4.2 and up
  • Built for compatibility with BlueWallet 6.1.5 and up
  • BlueWallet users may have to switch to "legacy" QR mode for now
  • For testing/development using SSH, the device name has been changed from "raspberrypi" to "seedsigner"
  • The best way to practice & get comfortable with signing is testnet
  • Test with small amounts of BTC first if starting with mainnet
  • Slightly rotate the SeedSigner screen to resolve glare/lighting issues
