How to set up a hardware wallet
A safe checklist — step by step, plus the most common mistakes that cost people everything.
A hardware wallet (Ledger, Trezor) is the safest way to store crypto — but only if set up correctly. One mistake during setup can wipe out your funds. Follow this checklist exactly.
Before you start
- Buy ONLY from the official manufacturer (ledger.com, trezor.io). Never Amazon, eBay, Allegro or marketplaces.
- Check the packaging — original seal, no signs of opening.
- Set aside 30–45 minutes of quiet time. Don't rush.
- Prepare 2–3 sheets of paper and a pen (or a metal seed backup).
Safe setup checklist
Check that the device looks identical to photos on the official site. If anything looks off — packaging tampered with, pre-set PIN, a paper with a 'ready' seed phrase — STOP. Return it.
Ledger Live or Trezor Suite — only from the manufacturer's official website. Type the address yourself. Verify the download signature if available.
Always choose 'Set up new device' — never 'Restore' unless you really are restoring your own wallet from a seed you wrote down yourself.
6+ digits, not your birthday, not 123456. After several wrong tries the device wipes itself — that's a feature, not a bug.
12 or 24 words generated by the device. Write them in order, on paper. Never photograph, never type into a computer or phone, never paste into any app.
The device will ask you to confirm a few words. Do it carefully. This proves your backup is correct.
E.g. a home safe and a separate location (family member, bank safety deposit box). Never both copies in the same building.
Send $5–$10 worth of crypto to your new wallet, then send it back out to confirm everything works. Only then move bigger amounts.
Update only via the official app, never via links from emails, Telegram or pop-ups.
🚩 Most common mistakes — DO NOT do this
- Buying a 'used' or 'discounted' hardware wallet on a marketplace — it may be tampered with.
- Photographing the seed phrase or storing it in cloud / notes / email / password manager.
- Entering the seed phrase on a website or in any app — no legitimate service ever asks for it.
- Choosing 'Restore from seed' with a phrase that came pre-printed in the box.
- Skipping the small test transfer and sending all your savings on the first try.
- Updating firmware from a link sent on Telegram, Discord or in an email.
- Telling anyone you own a hardware wallet, or how much crypto is on it.
✅ Final check
If your seed phrase is on paper, in two safe physical locations, and you've successfully sent a test transfer in and out — you're done. Welcome to real self-custody.
