Ledger Nano X Review
The original hardware wallet, now with Bluetooth
The Ledger Nano X is the best-selling hardware wallet in the world. That doesn't make it good. Ledger built its reputation on marketing, not security fundamentals. The 2020 data breach exposed customer addresses. The 2023 Recover announcement proved their firmware can extract your seed. If you're holding serious bitcoin, this isn't it.
Multi-Coin Warning
Supporting multiple cryptocurrencies means more code, more complexity, and more potential vulnerabilities. Most altcoins are scams anyway. The wallet makers who support them are prioritizing sales over your security.
About Ledger
Security Architecture
Closed-source secure element (ST33J2M0). Firmware is proprietary and cannot be independently audited.
| Secure Element | ST33J2M0 (closed-source, same family used in passports and banking) |
| Connection Methods | USB-C, Bluetooth |
| Display | 0.5" OLED (small, hard to verify addresses) |
| Passphrase Support | Yes |
| Multisig Support | Yes |
What's Good
- Market Leader: Ledger has the most users and widest ecosystem support. Most apps and services test with Ledger first.
- Bluetooth Convenience: Easy mobile use without cables. Good for quick transactions on the go.
- Multi-Coin Support: Supports thousands of cryptocurrencies. Good if you hold multiple assets.
What Could Be Better
Closed-Source Security
You cannot verify what the secure element firmware does. You must trust Ledger's claims about security.
Seed Extraction Capability
The Ledger Recover feature proved that Ledger's firmware can extract and transmit your seed phrase. Even if you don't use Recover, the capability exists in firmware.
Data Breach History
The 2020 breach exposed customer data leading to phishing, SIM swaps, and physical threats. Ledger stored data they didn't need.
Tiny Display
The 0.5" screen makes it nearly impossible to verify full addresses, increasing address substitution attack risk.
Supply Chain Vulnerabilities
The 2023 Connect Kit attack showed Ledger's infrastructure can be compromised to attack users.
Security Incidents & Controversies
Every company makes mistakes. What matters is how severe they are and what they reveal about priorities. Here's Ledger's track record:
Hackers stole personal data of 272,000 customers including names, addresses, and phone numbers. This led to targeted phishing attacks and even physical threats against customers.
Ledger announced a seed recovery service that revealed their firmware has always had the capability to extract seed phrases. This contradicted years of marketing claiming seeds never leave the device.
Ledger's JavaScript library was compromised, draining approximately $600K from users who interacted with affected dApps.

The Verdict
Look, the Ledger Nano X isn't a bad device from a pure hardware perspective.
It has bluetooth and closed source. Some people will like that.
Not Recommended
Multi-coin wallets aren't what I recommend for bitcoin storage. More code means more risk. At $99, you can get a Bitcoin-only device with a smaller, more auditable firmware.
Bitcoin-only, dummy.
I'm not going to help you buy a multi-coin wallet. Check out my Bitcoin-only recommendations instead.
