Kits and tools for running your own keys — sourced, assembled, and tested by hand. Open-source where it counts. Verify everything yourself.
An air-gapped, camera-and-QR-code based signing device built on open-source hardware and the open-source SeedSigner firmware. Available unassembled or pre-assembled & bench-tested — never pre-flashed, so you always install and verify the firmware yourself.
One-on-one help verifying, flashing, and using your SeedSigner — remote or in person. Never involves your seed phrase or real funds.
A desk clock showing block height, BTC price, and "Moscow time" (sats-per-dollar). Runs on public data by default; can point at your own node.
Stainless steel plates and a letter/number stamp set for a fire- and water-resistant backup of your seed phrase.
A snug, printed carry case for common hardware wallets and DIY signing devices. Protects the electronics, not a security feature on its own.
Holds signing devices, seed backups, and notes steady while you run a multisig setup or signing ceremony — fewer dropped cards, fewer mistakes.
A discreet printed box sized to hold a seed card, a stamped metal backup plate, or both.
Holds the Pi Zero, screen, and buttons in alignment while you build an unassembled SeedSigner kit. Only useful if you're building your own.
A ventilated printed case for a Raspberry Pi running your own Bitcoin full node — Umbrel, myNode, RaspiBlitz, or plain Bitcoin Core.
Everything sold here uses parts and designs you could source and assemble yourself, usually for less money. Here's the actual trade-off, no spin.
