The hardware
What is actually inside
The Nano X is built around an ST33J2M0 secure element certified to CC EAL5+, which is the same security-evaluation class used for payment cards and electronic passports. Private keys are generated inside that chip and never leave it.
That is the meaningful specification. Screen size and build materials matter far less than where the keys live and what standard the chip holding them was evaluated against.

The 500+ versus "thousands" distinction
Ledger's own page makes two different claims on the same screen: 500+ crypto supported through the Ledger Wallet app, and thousands of coins, tokens and NFTs supported through third-party wallets. Both are accurate, and they describe different experiences.
The first number is what you get inside Ledger's software, managed in one place. The second means connecting your Nano X to somebody else's wallet interface and using the device purely as a signer. If your assets fall in the gap between those numbers, budget for a clunkier setup than the marketing implies.
In the box
- 1 Ledger Nano X
- 1 USB-C to USB-A cable
- 3 recovery sheets
- 1 keychain strap
- 1 safety and regulatory leaflet
Note what is not in that list: a pre-filled recovery phrase. A device that arrives with words already written on the sheet is a scam, without exception. Ledger devices generate the phrase on first setup, in your hands.
The real debate
Closed firmware, and why people care
Ledger's firmware is not open to public audit. Its security rests on an independent certification of the chip and on trusting Ledger's engineering, rather than on code that anyone can read. Reasonable people land on both sides of this.
The argument stopped being theoretical when Ledger announced a seed-phrase recovery service. The backlash was not really about the feature. It was about what the feature proved: that firmware could be built to handle key material in ways many owners had assumed the hardware made impossible.
If your security model is "I trust a certification body and a company with a long track record," the Nano X is excellent. If your security model is "I trust code I or others can audit," then no certification substitutes for that, and you should buy accordingly rather than talking yourself into this device.
Separating two different things
Was Ledger hacked?
No Ledger device or secure element has been broken in the wild. What was breached, in 2020, was Ledger's e-commerce customer database, exposing the names and contact details of people who had bought hardware wallets.
The consequence was not stolen crypto. It was a list of confirmed crypto owners, with home addresses, circulating among scammers. Owners received convincing phishing emails and physical letters for years afterward, some containing tampered replacement devices.
Both facts matter and they are constantly conflated. The wallets held. The customer list did not. If you bought a Ledger before 2021, treat any unsolicited contact claiming to be from Ledger as hostile, and never enter a recovery phrase anywhere but the device.
What it does and does not stop
Three risks, one device
A hardware wallet solves exactly one of these cleanly. Knowing which one is the difference between being protected and feeling protected.
- 1
Someone steals the device
This is the risk the Nano X is built for, and it handles it well. Keys never leave the secure element, and the device is PIN-locked with a wipe after repeated failures.
- 2
Someone gets your recovery phrase
The device cannot help you here. Anyone holding those words owns the funds, with or without your Nano X. This is where almost every real-world loss happens.
- 3
Someone convinces you to approve a transaction
A hardware wallet signs what you approve. If you are tricked into approving a malicious contract, the secure element signs it faithfully. Read the screen, every time.

Your situation, our answer
If this is you, do this
Holding a meaningful amount long term
Yes. This is the use case
Cold storage on a certified secure element is exactly what the Nano X is for. Buy direct from Ledger, never from a marketplace reseller.
You want open-source firmware you can audit
Look at Trezor instead
Ledger's firmware is closed. If auditability is your security model rather than certification, that is a genuine dealbreaker and you should not talk yourself out of it.
Managing crypto mainly from a phone
The Nano X is the strongest pick
Bluetooth BLE 5.2 with real iOS and Android support is the feature that separates it from cheaper hardware wallets.
Holding under a few hundred dollars
Hard to justify the cost
A reputable software wallet is free. Buy hardware when the amount you are protecting clearly exceeds the price of the device.
You mostly hold assets outside Ledger's 500+ list
Check compatibility first
Support through third-party wallets is broad but the experience is not the same. Confirm your specific assets before buying.

How we scored this review
This is a documentary review. Every specification above was read from Ledger's own product page on August 16, 2026 and is cited. We did not buy and test a unit, and we do not claim hands-on testing we did not do.
| Criterion | Weight | Mark | Why |
|---|---|---|---|
| Security architecture | 25% | 4.8 | A CC EAL5+ certified ST33J2M0 secure element, the same class of chip used in payment cards and passports. |
| Asset support | 20% | 4.5 | 500+ assets through Ledger's own app, and thousands more through third-party wallets. The distinction matters and Ledger states both. |
| Transparency and auditability | 20% | 2.5 | Firmware is closed-source. You are trusting a certification and a company, not an audit you can run. |
| Connectivity and daily use | 15% | 4.5 | Bluetooth BLE 5.2 plus USB-C, with genuine iOS and Android support. The most usable hardware wallet in normal life. |
| Incident history | 10% | 3.0 | The 2020 e-commerce customer data breach exposed buyers to phishing for years afterward, even though no device or key was compromised. |
| Value for money | 10% | 4.0 | Priced above entry-level hardware wallets, and the secure element plus Bluetooth is what you are paying for. |
Weighted average: 4.0 / 5. Read our editorial policy.

Ledger Nano X FAQs
Is the Ledger Nano X safe?
The hardware itself is among the most rigorously certified in consumer crypto: a CC EAL5+ rated ST33J2M0 secure element, the same class of chip used in payment cards. Private keys are generated and stored inside that chip and never leave it. What the device cannot protect you from is a leaked recovery phrase or your own approval of a malicious transaction, which is how the large majority of real losses actually happen.
Was Ledger hacked?
No Ledger device or secure element has been broken in the wild. What was breached, in 2020, was Ledger's e-commerce customer database, exposing names and contact details of people who had bought a device. That produced years of targeted phishing and physical-mail scams aimed at Ledger owners. It is a serious incident, but it is a marketing-database breach and not a compromise of the wallets themselves. The two get conflated constantly.
Why do people criticize Ledger for being closed-source?
Ledger's firmware is not open to public audit, so its security rests on certification and on trusting the company rather than on code anyone can inspect. That tension became a public argument when Ledger announced a seed-phrase recovery service, because it demonstrated that firmware could be made to handle key material in ways users had assumed were impossible. If your security model requires auditability, a hardware wallet with open firmware is the more consistent choice.
How many coins does the Ledger Nano X support?
Ledger states 500+ assets through its own Ledger Wallet app, and thousands of coins, tokens and NFTs through third-party wallets connected to the device. Those are two different experiences: the first is managed inside Ledger's software, the second means using another wallet's interface with the Nano X as the signing device. Check your specific assets before buying. Figures from Ledger's product page, checked August 16, 2026.
Nano X or Nano S Plus?
The Nano X adds Bluetooth and a battery, which is the entire practical difference for most buyers. If you manage crypto from a phone, that is worth paying for. If you only ever plug into a laptop, the cheaper model does the same security job with the same class of secure element. See our Ledger brand review for how the whole device lineup compares.
Should I buy from Amazon or a reseller?
No. Buy hardware wallets directly from the manufacturer, every time. Supply-chain tampering is a real attack against hardware wallets, and a resold or pre-opened device is not worth the discount. If a device arrives with a pre-filled recovery phrase, it is a scam without exception.
Can I recover my crypto if I lose the device?
Yes, from your recovery phrase. That phrase, not the device, is what holds your funds. You can restore to a replacement Ledger or to any compatible wallet that supports the same standard. This is also why the phrase must be stored offline and never photographed, typed, or entered into any website.
Is a hardware wallet worth it for a small holding?
Probably not. A reputable software wallet is free and secure enough for amounts you could afford to lose. Hardware makes sense when the value you are protecting comfortably exceeds the price of the device. See our wallet comparison for the free options worth using first.
The bottom line
Should you buy the Nano X?
Buy it if you hold enough to justify the cost and you manage crypto from a phone. Skip it if auditable firmware is part of what you mean by security, because no certification will give you that. Either way, buy direct from Ledger.
