SeedSigner is a FOSS application that turns a Raspberry Pi Zero with a camera and screen into an air-gapped, stateless Bitcoin signing device. It handles BIP39 seed creation, SeedQR transcription, and QR-based transaction signing entirely offline.
Use cases
- build a cheap air-gapped bitcoin hardware wallet
- sign bitcoin transactions offline via QR codes
- generate a BIP39 seed phrase from dice rolls
- set up a multisignature bitcoin wallet
- transcribe a seed phrase into a printable SeedQR
- store bitcoin private keys without any network connectivity
When to choose
- you want a sub-$50 DIY signing device with verifiable, reproducible builds
- you need stateless operation where secrets never touch persistent storage
- you prefer fully open-source, community-maintained bitcoin tooling
- you want multisig wallet coordination with QR-based data exchange
When to avoid
- you want a plug-and-play commercial hardware wallet with warranty and support
- you need altcoin support beyond Bitcoin
- you are uncomfortable assembling hardware components yourself
- you need wireless connectivity or persistent key storage on the device
