{"product_id":"seedsigner-orange","title":"SeedSigner - DIY Kit - Orange - Pre-Assembled","description":"\u003cp\u003eSeedSigner is a bitcoin signing device that remembers nothing. It has no Wi-Fi, no Bluetooth and no storage where a seed could stay behind. Pull the plug and everything you loaded is gone. At the next start you scan your seed as a QR code from paper or steel, and a few seconds later it is ready again.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDelivered pre-assembled.\u003c\/strong\u003e With us, the DIY Kit arrives fully built. Raspberry Pi, display, camera and enclosure are already put together, so there is nothing to plug in, screw or solder. Connect a Micro-USB power source and SeedSigner starts up.\u003c\/p\u003e\n\u003cp\u003eIt talks to your wallet software through its camera and display. Sparrow shows the transaction as a QR code, SeedSigner reads it, and you check the recipient and the amount on its screen. Once you confirm, it shows the signature as a QR code for your computer to read back. The two devices are never connected by a cable.\u003c\/p\u003e\n\u003cp\u003eThe software is open source and built by a community of volunteer developers, supported by the Human Rights Foundation. The images can be built reproducibly, so you can check for yourself that the file on your card matches the published source code.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat SeedSigner does\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eGenerates a 12- or 24-word seed from dice rolls or from a camera image\u003c\/li\u003e\n\u003cli\u003eShows your seed as a SeedQR to copy onto paper or stamp into steel\u003c\/li\u003e\n\u003cli\u003eChecks and signs transactions (PSBT) via QR code, Taproot included\u003c\/li\u003e\n\u003cli\u003eCo-signs in multisig wallets and verifies change addresses\u003c\/li\u003e\n\u003cli\u003eDisplays receive addresses on the device so you can compare them with your wallet\u003c\/li\u003e\n\u003cli\u003eBIP39 passphrase, BIP-85 and message signing\u003c\/li\u003e\n\u003cli\u003eImports Electrum seeds\u003c\/li\u003e\n\u003cli\u003eMenus in 22 languages\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWorks with\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSparrow Wallet, Nunchuk, Specter Desktop, BlueWallet and Keeper\u003c\/li\u003e\n\u003cli\u003ePower via Micro-USB, for example from a power bank or a USB charger\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eProduct details\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOrange enclosure with two grips\u003c\/li\u003e\n\u003cli\u003e1.3-inch colour display, 240 × 240 pixels\u003c\/li\u003e\n\u003cli\u003eControls: joystick and three buttons\u003c\/li\u003e\n\u003cli\u003eCamera for reading QR codes\u003c\/li\u003e\n\u003cli\u003eComputer from the Raspberry Pi Zero range\u003c\/li\u003e\n\u003cli\u003eSeedSigner OS with Wi-Fi, Bluetooth and USB data removed\u003c\/li\u003e\n\u003cli\u003eNo persistent storage for seeds, no battery\u003c\/li\u003e\n\u003cli\u003eMade in Germany\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eIn the box\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSeedSigner DIY Kit, pre-assembled in its orange enclosure\u003c\/li\u003e\n\u003cli\u003emicroSD card with SeedSigner OS\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003ePlease note: SeedSigner has neither a secure element nor a PIN. While a seed is loaded, anyone holding the device can display it, so switch it off once you have signed. Because it remembers nothing, you need your backup every time you start it. Without a SeedQR you enter 12 or 24 words with the joystick. You install updates yourself by writing the new version to the microSD card. There is no manufacturer support for the software.
