When you open the box you'll usually find the hardware wallet, a short USB cable, a recovery sheet for the seed phrase, and simple printed instructions. (Image placeholder below.)
Check the package for obvious tampering and compare the contents to the included checklist. I believe the clearest red flag is any broken seal or missing recovery sheet — stop and contact support channels before proceeding.

Before setup, confirm basic system compatibility and safety steps. Most modern desktop OS versions with a USB port will work; the companion desktop app is required to manage accounts and install apps. If you want to use browser integrations or mobile options later, review connecting-desktop-mobile and ledger-live.
A quick checklist:
And don't install anything from unverified third-party sources.
Below is a practical, step-by-step guide to initialize the device and add your first accounts. This covers the classic desktop-first flow.
Plug the device into your computer’s USB port. The device screen should light. If it remains blank, try a different USB port or cable.
Follow on-device prompts to create a new wallet. You will be asked to choose a PIN (4–8 digits on many models). The device itself generates the seed phrase; the companion app should never generate it for you.
I noticed that setting a memorable-but-not-obvious PIN reduces the temptation to write the PIN down where an attacker might find it.
The device will display a 24-word seed phrase (BIP-39 compatible). Write these words in order on the provided recovery sheet. Never copy the seed phrase digitally (no photos, no cloud notes). Consider a metal backup plate for long-term durability (see metal-backup-plates).

Install the official desktop companion application to manage device apps and accounts. Use it to install coin-specific apps on the device (this model has limited internal storage; you may need to remove and reinstall apps as you add more coins).
Note: "preloaded wallets" vary by packaging and time of purchase. Many units ship with minimal or no pre-installed apps, so you should plan to install the apps you need via the companion app.
See add-accounts-apps for details.
Add a Bitcoin or Ethereum account in the companion app. Always verify receiving addresses on the hardware wallet's screen before sending funds. This ensures a compromised computer isn't substituting addresses.
If you use browser integrations (for example to connect to DeFi interfaces), follow best practices in metamask-setup and myetherwallet-guide.
Firmware updates change the device's code and sometimes its protections. Install firmware only via the official companion app, and verify the device prompts during updates. The companion app will usually display a firmware fingerprint or signature to confirm authenticity.
Why update? Security patches, new coin support, and improved UX are typical reasons. After using this model for several months I installed two firmware updates that fixed small bugs and added coin support.
See step-by-step: firmware-updates and verify-firmware.
The device is USB-only (no Bluetooth). That reduces remote attack surface. But limited app storage means you will uninstall and reinstall coin apps when switching between many supported cryptocurrencies. That’s normal, but slightly inconvenient if you manage dozens of assets.
What I've found: uninstalling an app does not delete on-chain funds — the private keys remain safe as long as the seed phrase and PIN are intact. (Still, don't make uninstall/install a habit while transferring assets.)

Key points about the device architecture:
If you prefer an air-gapped workflow, see air-gapped for alternatives. USB-only can be an advantage (fewer wireless attack vectors). But it also means mobile Bluetooth wallets aren't applicable here.
Seed phrases are normally 24 words (BIP-39). You can optionally use a passphrase (commonly referred to as a 25th word). That creates an additional hidden account derived from the same seed.
A passphrase increases security but also increases complexity and recovery risk. Lost passphrase = effectively lost assets (unless you documented and stored it securely). I recommend metal backups for the seed phrase and a separate secure plan (geographic split, multi-signature for large holdings). See passphrase-25th-word and shamir-backup-slip39.
Recovering on a desktop wallet is possible (BIP-39 compatible wallets). But entering a seed into a hot wallet is higher risk; only do this if you understand the trade-offs. See restore-recovery for full steps.
| Pros | Cons |
|---|---|
| Hardware storage of private keys (secure element) | Limited internal app storage — juggling apps is required |
| USB-only reduces wireless attack surface | No Bluetooth means less mobile convenience |
| Straightforward PIN + seed setup | Learning curve for passphrase and multisig use |
| Broad third-party wallet and chain support | Not air-gapped; some advanced users prefer cold-signing setups |

Who should look elsewhere:
See model-compare for alternatives.
Common errors I see: buying from unofficial sellers, photographing the seed phrase, entering a seed on an online device, and not verifying receiving addresses on the device screen. What happens if a device is lost or broken? See device-broken and backup-and-recovery.
If the device fails to connect, try these steps:
But don't panic — the seed phrase is your recovery path.
Q: Can I recover my crypto if the device breaks?
A: Yes. Recover using the seed phrase on a compatible hardware wallet or a trusted recovery tool (prefer hardware). See restore-recovery.
Q: What happens if the company goes bankrupt?
A: Your private keys and seed phrase are under your control. Company failure affects software updates and support, not the cryptographic keys themselves (but you may lose convenience). See company-risk.
Q: Is USB safe for a hardware wallet?
A: USB is acceptable because signing happens on-device. Still, always verify transaction details on the device screen and use a trusted host computer. See connectivity-usb-bluetooth-nfc.
This hands-on unboxing and setup walkthrough covers the typical flow for getting a Nano S up and running: check the seal, initialize on-device, write your 24-word seed phrase, install apps through the companion app, and always verify addresses on the device screen. In my experience, the most common mistakes are human (seed handling and buying from unofficial sellers), not technical.
Next steps: review seed-phrase for backup best practices, compare models at model-compare, and check where-to-buy-safely before purchase. If you want a step-by-step visual, see setup-initial for screenshots and alternate flows.
