Testing a backup before you trust it — the step that turns a setup into a real one

Do this once, right after setup, and before you move any meaningful amount of Bitcoin into the wallet. The whole point is to catch a mistake while it costs you almost nothing.

1. Send a tiny test amount to the wallet first, roughly the value of a coffee up to a small dinner. Enough to confirm a real balance appears, small enough that a fumble does not hurt.
2. Wipe the hardware wallet. This is the factory reset in the device's settings. It erases the keys from the device, so now the only way back is your written backup. That is exactly the situation you want to practice.
3. Restore from your written words. Type your seed phrase back into the device's recovery flow, exactly as written, including your passphrase if you added one.
4. Check that it matches. The same receiving addresses should appear, and your tiny test balance should show up again.
5. Prove it can spend. Send the test amount to another address and back. This confirms the restored wallet can actually sign transactions, not just display a balance.

If every step works, your backup is now a verified fact instead of a guess. If any step fails, you just found the problem at the cheapest possible moment. And if the restore itself fails, stop — this is exactly why you checked the written words against the device before wiping it. Go back to that still-intact copy, re-check it word by word, and re-enter it carefully; only the test amount is at stake. Do not fund the wallet for real until the rehearsal passes cleanly.

This rehearsal is not busywork. It quietly checks for the exact mistakes that cause people to lose Bitcoin, the ones that stay invisible until the day you need the backup and it is too late:

• A miswritten word. One wrong or misspelled word in your seed phrase. This is the most common error, and the wallet's built-in checks will not always catch it.
• A missing piece. A word left off, or a passphrase you forgot you set. A restore either produces your wallet or it does not, and now you know which.
• A wrong assumption. You thought the setup worked one way; it actually works another. The restore shows you the truth.
• Device surprises. The hardware or its software does not restore the way you expected. Better to learn that now.

You are not testing whether you are smart. You are testing whether the words on that page really rebuild your wallet. That is the only question that matters.

Almost nobody skips this step on purpose. What happens is that something easier gets done in its place and feels like it counted. Each of these is worth knowing about, because each one leaves a real gap:

• Reading the words back against your notes. This tests your handwriting, not your wallet. A word copied as a different valid word reads perfectly, can pass the wallet's own checks too, and opens somebody else's empty wallet without a murmur.
• Typing the phrase into a site that offers to check it for you. There are pages that will validate a seed or show you its balance. Handing your words to a website is handing over the wallet, and no answer it gives you is worth that — there is nothing it can tell you that a restore onto your own device cannot.
• Restoring into a wallet app on your phone or laptop. This genuinely does prove the words work in other software, which is the strongest version of the test — and it types your live seed into an internet-connected machine, which is the one thing this guide asks you never to do. We don't recommend it. A clean restore on your own hardware already answers the question.
• Watching the balance appear and stopping there. Good, but it only proves the words rebuild the right addresses. It does not prove the restored wallet can sign — which is why the rehearsal above ends by sending the test amount back out again.
• Rehearsing without the passphrase, when you use one. Then you have successfully tested a different wallet. The seed alone opens the decoy, and it will look entirely normal while it does.
• Doing it once the wallet is funded. The whole value of a rehearsal is that a mistake costs you nothing. Funding first spends that, and it is the one thing here you cannot get back.

Passing once does not mean passing forever. Over the years, small things drift: device software updates, your notes fade or go out of date, memory slips. A setup that worked at setup can quietly stop working. So check it again on a schedule, at least once a year. If you are holding a serious amount, every six months is cheap insurance.

You do not have to do the full wipe-and-restore every time. There is a lighter check for the in-between visits (below), and a full wipe-and-restore is worth repeating every couple of years, or any time something changes, such as a device software update, a move, or a change to your setup. When you do repeat the full test, put your backups away in their secure spot the moment you are finished, and keep the whole thing to a private, uncluttered space.

Between full rehearsals, there is a fast check that takes only a few minutes and never moves any Bitcoin. It is called signing a message, and most hardware wallets offer it as a built-in feature.

1. Pick a short phrase to sign, such as today's date or any sentence you like.
2. Use the wallet's "sign message" function to sign that phrase with your device.
3. Verify the signature. A valid result mathematically proves your device still has working access to your keys.

This does not move funds and does not expose your seed phrase. It proves the wallet is alive and can still sign, which is most of what you want to confirm on a routine check. Just remember what it does not prove: it does not test whether your written words are correct or whether the device would survive a full restore. So treat it as the quick pulse check, and keep doing the full wipe-and-restore now and then for the deeper assurance.
