About

Building a serious hardware wallet company

SeedMask is Bitcoin and Kaspa only — cold keys on device, watch-only Coordinator on desktop, and an honest path from firmware to funded team.

Origin

Why was SeedMask born?

Having crypto is the easy part. Maintaining it — storing seeds safely, tracking accounts, remembering passphrases and derivation details — is the real struggle.

One seed is hard enough. Multiple seeds, multiple accounts under each, passphrases on top of those — and suddenly you are not only securing coins. You are securing a map: which index, which derivation path, which passphrase belongs where.

Where do you put that map? In a book — someone finds it, or water and time destroy it. On a phone — malware and backups. On a “clean” spare phone — you still do not truly know what runs on it. On an air-gapped laptop writing to USB — the machine can still leave traces you never intended. Invent your own cipher alphabet — easy to forget; write the rules down — easy for someone else to reverse.

The almost-solution

There was a path that looked serious on paper: encrypted keypad USB, forever-offline phone, point-and-shoot camera with MicroSD, standalone CD duplicator, portable CD/DVD player, printer with USB — then split each 24-word seed into quarters across those media. First six words photographed to MicroSD. Next six onto the encrypted stick and burned to disc. Next six from an air-gapped editor onto ordinary USBs. Last six written, scanned, copied, printer wiped. Multiple copies. Multiple hiding places. A ritual to reassemble when restore day came.

It felt complete — until you lived with it. Too many parts. Too many locations. Heat, moisture, and electrostatic discharge waiting to corrupt MicroSD, USB, and discs. SeedQR helps portability, but unprotected (or even “protected”) media still get lost, damaged, or stolen as physical objects.

What was actually needed

  • Something that does not silently rot
  • Physical and portable
  • Easy to recover when life goes wrong
  • Highly secure
  • Writable — a real backup you can hold

Hiring that into existence costs real money and rare trust. The other path: build it yourself. The idea of how it must work was already clear — even before the code. With AI and many iterations, SeedMask took shape.

The core bargain is simple and strict: a writable backup code plus your own password always derives your seed the same way. No maybe. No lucky guesses. Strong password discipline and careful password storage are still on you — but the recovery path is deterministic.

You can carry the backup code. Leave it in a drawer. Entrust it to someone careful — or even someone you do not fully trust — if the password is strong enough that the code alone is useless. That is not a license to be reckless with photos and printouts. It is a measure of how the design is meant to work: the backup code is portable; the password is the gate.

SeedMask was born because the DIY vault stack was too fragile for real life — and self-custody deserved something physical, recoverable, and honest about where the risk still sits.

The name

Why “SeedMask”

It masks your seed

Your seed phrase is the master key to your funds. SeedMask is designed so that seed never leaves the device — in the final hardware form, the plan is that it stays masked inside SeedMask and never gets out onto a computer, phone, or the network.

Safer to store, easier to live with

Masking the seed is not only about keeping it offline. It is about storing it better, safer, and more conveniently — so you can use Bitcoin and Kaspa without writing secrets into everyday apps or leaving recovery words exposed.

At first, SeedMask can sound dangerous or even contradictory — as if something were being hidden from you. That is far from the truth. The name is a promise of protection: SeedMask aims to become a wallet that guards your seed, generates it safely and with high entropy, and keeps it masked from the places that leak — so the product can live up to what it is called.

Vision

Keys stay on SeedMask

Keys on device. Watch-only on desktop. Signing stays offline.

SeedMask is the vault you hold: seed generation, storage, and signing stay on the hardware — masked from phones, browsers, and everyday machines that were never built to keep a seed safe.

Focus

Bitcoin & Kaspa only

Satoshi’s vision. Two coins means clearer signing screens and a smaller attack surface than a multi-coin wallet.

Every extra chain adds formats, fees, and confirmation edge cases at the moment you should be careful. SeedMask stays narrow on purpose — Bitcoin and Kaspa done properly, not a crowded catalog of half-supported assets.

Stance

100% open-source

Firmware, Coordinator, and the full signing path — published so anyone can audit it.

Closed wallets ask you to trust a black box. SeedMask is built so independent eyes can inspect how keys are handled, how updates ship, and how the air-gapped path actually works — transparency as a custody requirement, not a slogan.
