How Does SeedSigner Work?

SeedSigner is based on the Raspberry Pi Zero (Version 1.3) – a specific model without WiFi or Bluetooth, ensuring your private keys remain secure and isolated. Communication with wallet software is done via a secure QR code exchange:

1️⃣ The wallet displays a QR code with transaction details
2️⃣ SeedSigner scans the code & displays the details for confirmation
3️⃣ SeedSigner signs the transaction and generates a signed QR code
4️⃣ The wallet scans the signed QR code to broadcast the transaction to the network

SeedSigner is compatible with major Bitcoin wallets, including:
✅ Specter Desktop

Note: SeedSigner does not store private keys permanently. It is ideal for users who want to manage their own air-gapped Bitcoin wallet.
