The goal of SeedSigner is to lower the cost and complexity of Bitcoin multi-signature wallet use. To accomplish this goal, SeedSigner offers anyone the opportunity to build a verifiably air-gapped, stateless Bitcoin signing device using inexpensive, publicly available hardware components (usually < $50). SeedSigner helps users save with Bitcoin by assisting with trustless private key generation and multi-signature wallet setup, and helps users transact with Bitcoin via a secure, air-gapped QR-exchange signing model.
This is a printed version of the model that can be found here: GitHub - SeedSigner/seedsigner: Use an air-gapped Raspberry Pi Zero to sign for Bitcoin transactions! (and do other cool stuff)
The case does not include any electrical components such as the Raspberry Pi Zero, Pi Zero-compatible camera, or the Waveshare 1.3" (240 x 240 pixel) LCD.
NB We actually recommend the SeedSigner Open Pill Case as it is more compact and easier to operate without the buttons.
