SeedSigner Plus Smartcard Edition

ShieldSigner: a SeedSigner fork by YTCryptoGuide, with a Smartcard Hat and super slim case designed by @xmrstreet.

The Smartcard Hat combines the power of SeedSigner's stateless signing with the security and convenience of SeedKeeper smartcards. These devices allow you to load your keys into the device via SeedKeeper without ever exposing them to your surroundings. Your secrets are protected by a PIN code, and loading keys into your device is fast and simple.

There is no need to keep a SeedQR visible where others might capture it. Using a smartcard lets you safely store your backups without having to retrieve them each time you transact, making it an ideal setup for a daily driver. The operating system also includes a suite of built-in tools for interacting with your smartcards and their features.

The larger display makes verifying bitcoin address strings very easy. Improvements over the original SeedSigner hardware profile include:

• Larger 2.8" IPS 240x320 display
• Onscreen text that is easier to read
• More efficient outgoing QR-data transfer
• Intuitive DPAD style controls
• Spring-loaded microSD port
• Conveniently located USB-C power-only port
• Raspberry Pi Zero v1.3 board, with no WiFi or Bluetooth communication capability
• Buttons and DPAD printed in TPU for great comfort

3D printed case colour options

• Body: Black, Orange, Red, Translucent Orange
• TPU button: Black, Orange, Translucent Orange
• Faceplate: Black, Orange, Red, Translucent Orange

Cable included: choose your cable above, either a 25cm USB A to USB C cable or a 25cm USB C to USB C cable.

The SD card is loaded with the latest SeedSigner smartcard fork from YTCryptoGuide. This OS does not get the same level of scrutiny as the SeedSigner OS, so do your own research and verification before you commit significant savings.
