Ship first

Devices leave in reservation order, starting spring 2027.

Shape the build

Beta app access and a monthly build note where feature votes count.

Recovery kit

A steel backup plate and two spare recovery cards with every early order.

Nothing is charged today. An email holds the spot.

We write once, when your batch is ready. Leave the list any time from that email.

A vault you actually want to open.

Cold storage has mostly been built for people who enjoy the setup. Everyone else keeps their coins on an exchange or in a browser extension because the safe option asks for a weekend of research.

Lumo starts from the opposite end. Setup is a guided ten minutes, every screen says what will happen before it happens, and the device stays offline for its whole life. The security model is the strict one; the experience is the friendly one.

Planned features for the first batch

Sign with a QR code, never a cable.

Air-gapped signing

No USB, no Bluetooth, no Wi-Fi. Transactions cross the gap as a scanned code.

Passphrase vaults

Up to five hidden vaults behind separate passphrases, each with its own balance view.

Multi-chain from one phrase

Bitcoin, Ethereum, Solana and the major EVM networks under a single recovery phrase.

Steel-ready backup

The plate layout matches the screen layout, so writing a backup takes minutes, not an evening.

Multi-sig ready

2-of-3 and 3-of-5 policies across devices, for treasuries and shared accounts.

Every release is reproducible and published for audit before it reaches a device.

  • Reproducible builds
  • Public report
  • Before first ship

Privacy first, and no account anywhere.

Lumo has no sign-up, no email requirement and no analytics on the device. The app reads public chain data; the pin, the passphrase and the recovery phrase never leave your hands.

  • No KYC
  • No device telemetry
  • Your own node, optionally
  • Duress pin
