What problems does SeedSigner solve?

– Creates a secure, air-gapped environment for private key generation

– Enforces strict separation between private key storage and protocol software / internet

– Lowers the barrier cost of multi-sig security (from several hundred to < $50)

– (mainly targeted at holders making relatively few txns)

What is an “air-gapped” signing model?

Breaks the “wallet” into 3 components”

– Private key storage

– Signing device

– Wallet coordinator software


“Airgapped” might mean:

– USB/SD card transfer

– Infrared light transmission

– Two-way QR code exchange

Why is “air-gapped” important?

– “Device that aren’t USB-connected are potentially more secure than devices that are USB-connected …”

– Air-gapping allows for strict controls of what data is permitted as input & as output
