Security, plainly stated
No device is "unhackable." Here's what ours actually does.
We don't make grand promises. We make a carefully engineered offline signer, honest documentation, and a team that answers its own support email.
- 01Offline key generationYour seed is generated on the device, by the device, and never transmitted anywhere — not to us, not to your computer.
- 02Physical confirmationEvery outgoing transfer must be reviewed on the wallet's own screen and approved with a physical button press.
- 03Open & inspectableFirmware source and hardware schematics are published for independent review. You can verify what you're running.
- 04Tamper-evident deliveryEach unit ships in sealed packaging with a verification procedure so you can confirm it arrived untouched.
Our hardware wallets are designed to hold your private keys offline, in cold storage. They are a dedicated security tool with no online financial features. You stay in sole control of your keys at all times.
How we build
Built in-house. Tested individually. Every unit.
Ermanno Moser builds its devices in-house. Each wallet is assembled, flashed, and tested individually before it ships, with no outsourced assembly and no anonymous support queue.
When you order from us you know exactly who built your device, and you can reach that person directly with questions, repairs, or custom requests.
Read the full story- Built to orderFlagship units are made in small batches — your wallet is built for you, not pulled from a warehouse.
- Repairable by designStandard fasteners, documented internals, spare parts available. We'd rather fix than replace.
- Honest claims onlyWe document what each device protects against — and what it doesn't. No security product should promise more.
