Ledger Nano S review

The Ledger Nano S is the hardware wallet that introduced millions of people to cold storage. Launched in 2016, this tiny USB device made keeping your crypto keys offline affordable and mainstream. But there is one thing you must know before buying: the original Nano S was discontinued in 2022 and replaced by the Nano S Plus. This Ledger Nano S review explains what made it great, why it has been superseded, and what current buyers and existing owners should do now.

The short version: the Nano S was an excellent, secure budget cold wallet in its day, built around a certified secure element. Today it is a legacy device with a tiny app storage limit and no active firmware support, so new buyers should choose the Nano S Plus instead, while existing owners can keep using it safely as long as they have their recovery phrase.

Ledger Nano S at a glance

What the Ledger Nano S is and how it works

The Ledger Nano S is a cold-storage hardware wallet: a small device, protected by a stainless-steel swivel cover, that keeps your private keys completely offline. You plug it into a computer by USB, confirm every transaction with the two physical buttons and the small screen, and manage your accounts through the Ledger Live app on desktop or mobile. Because the keys never leave the device, malware on your computer cannot steal them.

At its heart is a CC EAL5+ certified secure element, the same class of tamper-resistant chip used in passports and bank cards, which is what made the Nano S genuinely secure rather than just cheap. You set it up with a PIN and back it up with a 24-word recovery phrase, and that phrase is what lets you restore your funds on any compatible wallet if the device is ever lost.

Why the Nano S was discontinued

The Nano S was retired for one main reason: storage. It shipped with just 320KB of memory, enough for only around three to five coin apps at a time, so anyone holding a diverse portfolio had to constantly uninstall and reinstall apps. It was a real, everyday annoyance, and it is the single biggest weakness of the device.

The Nano S Plus fixes exactly this. It has roughly 1.5MB of storage, enough for around 100 apps installed at once, plus a larger screen, while keeping the same certified-secure-element approach and adding ongoing firmware support. Because the original Nano S has been removed from active firmware support and repairs are no longer offered, the Plus is now the direct, supported successor.

Security and the trust questions

On the device itself, the Nano S security model is sound: a certified secure element, offline keys, on-device transaction confirmation, and a 24-word recovery backup. No hardware exploit has drained Nano S devices that were used correctly, and the cold-storage fundamentals still hold up today.

An honest Ledger Nano S review, though, has to cover the two events that dented Ledger's reputation. In 2020, a breach of Ledger's e-commerce and marketing database exposed around a million customer emails and roughly 270,000 physical addresses and phone numbers. Crucially, no funds or recovery phrases were taken, the crypto itself was never at risk, but the leaked contact data fuelled a long wave of phishing and even physical-threat scams against Ledger owners. Then in 2023, the launch of Ledger Recover, an optional paid seed-recovery service, caused a major backlash because it showed that a sharded copy of the seed could be created off the device, which many users felt contradicted the promise that keys never leave the secure element. Recover is optional and off by default, but both episodes are worth weighing when you judge the brand.

Coin support and Ledger Live

Through the Ledger Live app, the Nano S supports more than 5,500 coins and tokens, and Ledger Live remains one of the more polished companion apps, letting you buy, swap, stake, and manage assets and even connect to Web3. The catch is the same storage limit: while thousands of coins are supported, the Nano S can only hold a handful of their apps installed at any one time, so heavy multi-chain users feel the squeeze quickly.

In everyday use, sending and receiving crypto is straightforward. To receive Bitcoin, Ethereum, or any other supported cryptocurrency, you open its app in Ledger Live, verify the receiving address on the device's own screen, and share it; to send, you confirm the details with the two buttons so nothing is broadcast to the blockchain without your physical approval. For first-time users this on-device verification of every address is the core habit that keeps funds safe, and it is a feature the Nano S handled well despite its small screen.

Where the Ledger Nano S falls short

The trade-offs are mostly about age. It is discontinued, so there is no active firmware support and no official repair, its 320KB storage is severely limiting, the screen is small and the two-button interface is fiddly for longer confirmations, and it uses an older micro-USB connection. Layered on top are the brand-trust questions from the 2020 data breach and the Ledger Recover controversy.

• Discontinued: no active firmware support or official repairs.
• Tiny 320KB storage: only a few coin apps at once, constant reinstalling.
• Small screen and two-button UX, less comfortable than modern wallets.
• Brand-trust caveats: the 2020 data breach and the 2023 Ledger Recover backlash.

Should you buy a Ledger Nano S in 2026?

For new buyers, no, not the original. There is no reason to buy a discontinued device when its direct successor fixes its biggest flaw for a similar price. If you want an affordable Ledger, buy the Nano S Plus, or the Bluetooth-enabled Nano X if you want mobile use. You get the same certified-secure-element security with far more storage and ongoing support.

• New buyers: choose the Nano S Plus (or Nano X), not the original Nano S.
• Existing Nano S owners: your device still works, and your funds are safe as long as you have your 24-word recovery phrase; upgrade when convenient.
• Either way: treat your recovery phrase as the real key, and never enter it anywhere online.

The bottom line

The Ledger Nano S earns its place in history: it made certified, secure cold storage affordable and brought hardware wallets to the mainstream. But in 2026 it is a legacy device, held back by tiny storage and no active support, and shadowed by Ledger's data-breach and Recover controversies. The security model it pioneered is still sound, so if you want that in a device you can actually buy today, get the Nano S Plus. Existing owners can keep using their Nano S safely, but the original is no longer the one to buy.
