Seedsigner+ Smartcard

The SeedSigner+ smartcard version is designed to deliver a greatly improved user experience. Its larger 2.8″ IPS display provides sharp, vibrant visuals with excellent readability. Combined with DPAD-style buttons for precise menu navigation, it makes interacting with the device easier, more intuitive, and faster.

The smartcard version combines the power of SeedSigner’s stateless signing with the security and convenience of Satochip SeedKeeper smartcards. These devices allow you to load your keys into SeedSigner via SeedKeeper without ever exposing them to your surroundings. Your secrets are protected by a PIN code, and loading keys into your SeedSigner is fast and simple. The Seedkeeper card can also store multisig descriptor or other passwords.

There’s no need to create a SeedQR anymore where others might capture it, but it still has that capability. Using a smartcard lets you safely store your backups encrypted without having to retrieve them each time you transact, making it an ideal setup for a daily driver. The firmware also includes a suite of built-in tools for interacting with your smartcards and their features.
