Ledger Nano S Plus
The Ledger Nano S Plus is Ledger's entry-level hardware wallet with a CC EAL6+ certified secure element, USB-C, OLED display, and support for 5,500+ cryptocurrencies across 50+ blockchains. It provides cold storage security without Bluetooth or batteries — a simple plug-and-sign device that keeps private keys offline.
Best budget hardware wallet for USB-only cold storage, skip if you need Bluetooth for mobile signing.
Where to Buy
Pros
- CC EAL6+ secure element (ST33K1M5) — highest security certification in consumer hardware wallets
- 5,500+ supported cryptocurrencies including Bitcoin, Ethereum, Solana, and all major tokens
- USB-C connection — modern and reversible
- Up to 100 apps installed simultaneously — manage many chains without swapping
- 21g and 62mm — smallest and lightest Ledger device
Cons
- No Bluetooth — requires USB cable for every transaction
- Small 128x64 OLED display makes verifying long addresses difficult
- Two physical buttons are less intuitive than touchscreen alternatives
- Cannot sign transactions on mobile without Bluetooth
Security Architecture
The ST33K1M5 secure element stores private keys in tamper-resistant hardware with CC EAL6+ certification — the same security standard used in passports and government ID cards. Private keys are generated on the device and never leave the secure element. Transaction signing happens inside the chip; the host computer only sees the signed transaction.
Ledger's custom BOLOS operating system runs on the secure element, isolating each cryptocurrency app from the others. A compromised Bitcoin app cannot access your Ethereum keys. This architecture is the core advantage of hardware wallets over software wallets — even a compromised computer cannot extract your keys.
The USB-Only Trade-off
No Bluetooth eliminates an entire wireless attack surface. Every Bluetooth device has a pairing vulnerability window and potential for relay attacks. By being USB-only, the Nano S Plus can only be compromised through physical access or a compromised USB connection — both significantly harder to execute remotely.
The trade-off is convenience. Every transaction requires plugging in the USB-C cable, navigating with two physical buttons on the tiny OLED, and confirming on the device. For daily traders, this friction adds up. For long-term holders who transact monthly, it is a non-issue.

Who Should Buy This
USB-C plugs into your computer. Ledger Live desktop app manages everything. No Bluetooth means one less wireless attack vector. 5,500+ coins cover virtually any portfolio.
No Bluetooth means you cannot sign transactions from a phone app. The Ledger Nano X adds Bluetooth for mobile Ledger Live. The Trezor Safe 5 adds NFC for tap-to-sign.
Better alternative: Ledger Nano X
No Bluetooth, no NFC, no battery, no wireless radio of any kind. The only data path is USB-C. Fewer attack surfaces than any wireless-enabled wallet. The secure element is CC EAL6+ certified.
Frequently Asked Questions
Ledger Nano S Plus vs Nano X: what is the difference?
The Nano X adds Bluetooth 5.0, a 100mAh battery for wireless operation, and a slightly larger physical size. The Nano S Plus is USB-C only with no battery. Both use the same ST33K1M5 secure element and support the same 5,500+ coins.
Is the Nano S Plus secure enough for large holdings?
Yes. The CC EAL6+ secure element is the same chip used in the Nano X and Ledger Flex. The security architecture is identical. The only difference is the lack of Bluetooth, which some consider a security advantage.
How many cryptocurrencies can the Nano S Plus hold?
Up to 100 apps simultaneously, each supporting one or more blockchains. With 5,500+ supported assets across 50+ chains, virtually any cryptocurrency portfolio can be managed. Apps can be added and removed without affecting stored keys.
Can I use the Nano S Plus with my phone?
Not wirelessly. The Nano S Plus requires a USB-C connection. Some Android phones support USB-C OTG for direct connection, but iOS devices cannot connect. For mobile use, the Nano X with Bluetooth is required.
What happens if I lose my Ledger Nano S Plus?
Your funds are safe. The device is PIN-protected (3 wrong attempts triggers a wipe). Your 24-word recovery phrase, written down during setup, can restore all accounts to a new Ledger device or any compatible wallet.
