Tuga had a cat flap before this one. It worked, it was perfectly adequate, and it was eventually replaced — not because it broke, but because the hinge had been designed in a decade when nobody expected a cat to use it four thousand times a year. It still opened. It just wasn't getting any better.

Ledger's Nano S has reached that point. After nearly a decade as the device that introduced most people to self-custody, it has been retired: software support has ended, and the hardware's memory limits meant it was never going to keep up with what people now expect to run on it.

If you own one, this is not an emergency. It is, however, something to handle on purpose rather than by accident.

1. First: Your Coins Are Not in Danger

Say it clearly, because retirement announcements generate exactly the kind of urgency scammers harvest.

Your Nano S still works, and your coins are not on it. They live on the blockchain. The device holds a key, and your recovery phrase is the real asset. An unsupported device doesn't lose funds — it stops getting updates and stops supporting new applications.

What you should not do: panic, rush, or respond to any message claiming Ledger needs you to "migrate" your wallet by entering your recovery phrase somewhere. There is no such process. Every end-of-support announcement in this industry is followed by a wave of phishing built on it.

2. What Replaces It: the Nano Gen5

Ledger's revamp of the classic line is the Nano Gen5, and it's a genuine generational jump rather than a refresh.

The headline change is the touchscreen. The Nano S was two tiny buttons and a one-line display — the thing that made verifying a long address on-device a small act of endurance. The Gen5 puts a proper screen in the same pocketable form factor, and since "read what's actually on the device screen before confirming" is the single most important habit in self-custody, making that screen usable is a security improvement dressed up as a convenience one.

Beyond that: far more memory than the Nano S could offer, so you aren't uninstalling one app to make room for another, and it doubles as a security key with passkey support — meaning the same device can handle the hardware-key login I recommended in the article about securing everything around your bitcoin. One object, two jobs, both of them things you should already be doing.

It currently sells for around 769 zł / ~$179, in four colours.

The honest framing: the touchscreen and the extra memory make it nicer and easier to use correctly. They don't make the underlying security model fundamentally different — it's the same secure-element approach, and your recovery phrase is still the thing that matters. And Ledger isn't the only serious option: Trezor, BitBox and Coldcard are all real devices, and Coldcard in particular is built for the air-gapped and multisig workflows I wrote about recently. I'm writing about this one because it's the natural path for the very large number of people holding a Nano S that just reached the end of its life.

3. The Migration, Step by Step

Not complicated, and the order matters:

1. Set up the new device first. Let it generate its own fresh recovery phrase. Write it on paper now, metal later, and treat it as a completely new secret — because it is.
2. Do the restore drill before moving anything. Wipe the new device, restore it from the new phrase, confirm it comes back. Twenty minutes.
3. Send a small test amount from the old wallet to the new one and confirm it arrives.
4. Move everything else, in as few transactions as fee rates allow, during a quiet period.
5. Then wipe the old Nano S. Keep it as a souvenir or retire it — but don't leave a funded wallet on a device you've stopped maintaining.

Don't simply restore the old phrase onto the new device. You can — the standard is shared — but a migration is the perfect moment to retire a seed that has been through a decade of your life, several computers, and whatever your younger self did with a photo of it. New device, new secret, clean slate.

4. Buying It Without Repeating This Month's Disaster

This matters more than which model you pick, and it is extremely current. In October 2026, Ledger users reportedly lost tens of millions after devices that passed through one reseller were allegedly tampered with before sale. No cryptography was broken. The seed was simply known to someone else before the buyer ever opened the box.

So, the rules for buying any hardware wallet, in order of importance:

• Buy from the manufacturer or an official channel. Ledger's own site is the gold standard. On a marketplace, buy only from the manufacturer's official storefront — check the "sold by" line and make sure it says Ledger, not a third-party seller with good reviews and a better price.
• Never used. Never a bargain. Never a gift from someone you wouldn't hand your bank card to.
• The device must arrive with no wallet on it. It generates the phrase, on its own screen, in front of you, and you write it down. If a recovery sheet arrives already filled in, you are holding a theft in progress.
• Run the genuine check and update the firmware from the official app before funding — while understanding that this proves the hardware is authentic, not that your seed is unknown to someone else. Provenance protects you. Attestation alone does not.
• Buy the steel backup at the same time. Paper survives everything until the one day it doesn't, and the plate costs a fraction of the device.

👉 You can get the Nano Gen5 here: https://link.amazon/B03l7WkXz — sold by Ledger, which is exactly the "official storefront" condition above. As with everything on this site, that's an affiliate link: it costs you nothing extra and it helps feed the street cats. Buy wherever you like — just follow the rules above wherever that is.

5. While You're In There

A device migration is the natural moment to fix the things everyone postpones:

• Move the backup from paper to metal, in two separate locations.
• Write the letter — what exists, where the backups are, which app opens the device, who to call.
• Switch to native SegWit addresses if you're still on legacy, and stop paying the old-format tax on every transaction.
• Set the new device up as your security key for your email and exchange logins while it's in your hand.
• Do the restore drill, and put a yearly reminder in the calendar to repeat it.

None of that is about the new hardware. All of it is easier on the day you're already elbow-deep in your own setup.

The Point

The old flap still opened. Replacing it wasn't a rescue — it was maintenance, done at a moment of my choosing rather than in February, with a broken hinge and a cat on the wrong side of the door.

Your Nano S is fine today. Retire it deliberately, generate a fresh secret while you're at it, and buy the replacement somewhere whose chain of custody you can actually describe.

It isn't an emergency. That's exactly why it's a good time to do it properly. 🐾⚡
