Hands-on summary
This is a hands-on review of the Nano S hardware wallet. I used one as my day-to-day cold signer for about six months while testing Bitcoin, Ethereum, and several token flows. Short version: it's a compact, USB-only hardware wallet designed primarily for basic self-custody and secure key signing. I noticed the limited on-device app capacity early on (more on that below). But for straightforward Bitcoin and Ethereum storage, the device performs predictably and securely.
This review pulls together setup notes, security architecture, seed phrase handling, common issues (for example, "ledger nano s not connecting to etherium wallet"), and practical recommendations. If you want the step-by-step install guide, see the setup guide.
Unboxing & first impressions
The unboxing is minimal. In the box: the device itself, a USB cable, a recovery card for the seed phrase, and a few basic accessories (lanyard, stickers). The screen is small but readable. Build quality feels solid for a low-cost hardware wallet.
My first impression: straightforward hardware with no frills. The lack of wireless radios (this model is USB-only) keeps the attack surface smaller. I appreciated that during initial setup the device walks you through PIN creation and writes the 24-word seed phrase to the supplied recovery card.
Step-by-step setup (How to set up the Nano S)
How to set up the device, in practical steps I used:
- Plug the device into a desktop USB port and power it on.
- Set a PIN on the device screen (choose something memorable but not obvious).
- Record the 24-word seed phrase exactly as shown. Read every word aloud if that helps. (Do not take photos.)
- Confirm the seed phrase when prompted by the device.
- Install the companion desktop app and use it to manage apps and accounts. See the companion app walkthrough in the desktop app guide.
- Add accounts for each blockchain you plan to use (Bitcoin, Ethereum, etc.) and test a small transfer first.

Daily usage, wallet capacity & supported currencies
A recurring question is about wallet capacity: "ledger nano s wallet capacity". In short, the device stores a limited number of blockchain apps on its internal memory at once. In practice that means you can manage many currencies overall, but only a handful of apps are installed simultaneously (app size matters). In my testing that translated to being able to handle core Bitcoin and Ethereum flows easily, but juggling many chains like Solana, Tezos, and heavy token collections required frequent app swaps via the host app.
So what about supported currencies ("ledger nano s wallet currencies")? The device can secure private keys for Bitcoin, Ethereum and many other blockchains through the companion app and third-party wallets. For some chains (Solana, certain EVM-compatible networks, Tron), you'll use a third-party wallet integration rather than the companion desktop app. See the compatibility list in supported coins & networks for specifics.

Security architecture & firmware verification
The device uses a secure element to protect private keys and performs on-device transaction signing so keys never leave the hardware wallet. Firmware attestation is handled by the companion app; always verify firmware authenticity before use. I regularly checked firmware integrity using the official verification steps in the firmware update guide.
Air-gapped can mean different things. This model is not an air-gapped signer by default since it connects over USB. That said, it still performs on-device signing. If you need fully air-gapped workflows, see advanced guides such as advanced air-gapped.
What about connectivity security? USB-only reduces wireless attack vectors (Bluetooth and NFC bring other trade-offs). For a deeper read see Bluetooth/USB/NFC security.
Seed phrase management & backups
The device generates a seed phrase during setup (typically 24 words using BIP-39). This seed phrase is the master key to your crypto. I recommend a metal backup plate for long-term durability — paper and cardboard degrade. For resilient strategies, consider SLIP-39 (Shamir backup) if you want split-shared recovery; more on that in seed phrase management and SLIP-39.
Passphrase (the optional 25th word) adds a layer of secrecy, but it introduces recovery complexity. Use the passphrase (25th word) guidance before enabling it. If you lose the passphrase, the seed phrase alone will not recover funds.
Multisig and advanced setups
Multisig (multi-signature) dramatically reduces single-point-of-failure risk. You can combine multiple hardware wallets or co-signers so that a single lost device doesn't lose assets. This hardware wallet is compatible with common multisig setups via compatible wallet software. If you want to explore multisig for stronger long-term custody, see the detailed multisig guide.
In my experience, multisig adds complexity but is worth it for higher-value vaults or inheritance planning.
Troubleshooting: common connectivity and app issues
Common user searches show problems like "ledger nano s not connecting to etherium wallet", "ledger nano s my ether wallet", "ledger nano s ripple wallet not opening", or "ledger nano s tronscan no open wallet". Here are practical fixes I use:
- Check the USB cable and try another port. Many failures are hardware-cable problems.
- Unlock the device and open the correct blockchain app on the device before connecting the host wallet (Ethereum app for Ethereum-based flows).
- Make sure the host app or website supports the device (some wallets require a bridge or extension).
- Update the companion app and firmware (but only via official update routes). See troubleshooting steps in troubleshooting connectivity.
- For mobile connections, ensure OTG support and correct adapter; for Bluetooth-capable models use the secure pairing process described in Bluetooth/USB/NFC security.
If an address doesn’t appear where expected, check which account index and passphrase are in use — different passphrases create distinct wallets.
Feature comparison & who this is for
Pros and cons (observed in hands-on use):
- Pros: compact, robust PIN + secure element protection, predictable signing UX, strong companion app ecosystem.
- Cons: limited on-device app capacity, USB-only (no native air-gapped mode), small screen for extended review tasks.
Who this wallet is best for:
- Beginners and intermediate users prioritizing basic self-custody and on-device signing.
- People who primarily store Bitcoin and a few other major chains and don’t need many apps installed simultaneously.
Who should look elsewhere:
- Users with large token collections, heavy Solana or NFT workflows (consider models with larger app capacity).
- Those who need frequent mobile/Bluetooth use or fully air-gapped signing on a regular basis.

FAQ
Q: Can I recover my crypto if the device breaks?
A: Yes — with the seed phrase you can restore your accounts to another compatible hardware wallet or supported host app. See restore process.
Q: What happens if the company goes bankrupt?
A: Your private keys live with you (non-custodial). The hardware maker’s business outcome does not erase your seed phrase. Still, check guidance at company bankruptcy scenarios.
Q: Is Bluetooth safe for a hardware wallet?
A: Bluetooth introduces additional attack surface. For Bluetooth-specific trade-offs, read Bluetooth/USB/NFC security.
Conclusion & next steps
The Nano S hardware wallet is a practical, low-friction entry point to self-custody. In my testing it performed reliably for core Bitcoin and Ethereum workflows, with the main compromise being limited app capacity. Want a full installation walkthrough or firmware verification steps?
