Check a seed phrase you already have — and see the addresses it controls, before you trust them with anything.
Every keystick does two things: generate a brand-new wallet, or check a seed phrase you already hold. The second is the restore function. It takes a phrase you already have and shows you the addresses it controls — entirely in memory, on that one screen, storing nothing.
Confirm the words you wrote down actually produce your addresses, before you send any crypto to them. A mis-copied word or a wrong order is the most common way people lose a brand-new wallet — this is how you catch it while it still costs nothing.
Re-derive your receive addresses from a phrase you already hold, entirely offline, without ever typing your seed into a phone, a browser, or any connected device.
Boot the stick, or open the Mac app, exactly as you would to generate a new wallet.
At the opening menu, instead of pressing Enter to generate, type the word restore and press Enter.
Type your phrase with all the words on one line, separated by spaces, then press Enter. If it is not a valid phrase — a typo, a wrong word, or words in the wrong order — the stick says so and asks you to check your paper and try again. It will not continue from an invalid phrase.
The stick shows the Bitcoin, Ethereum/EVM, and Solana addresses that phrase controls. If they match the addresses you expected, your backup is good.
Power off. On a PC the environment is destroyed as the power leaves it; the Mac app simply exits. Nothing was saved — everything is gone except the paper in your hand.
The word “restore” means one thing here: re-deriving the addresses from a phrase you already have, so you can check it. It is not a way to get back a phrase you have lost.
Only ever type your seed into the keystick itself, or into a dedicated offline device. Never type it into a phone, a browser, or any online computer “just to check” — a phrase typed into a connected device is a phrase you no longer control. The restore function exists so that you never have to.
