- The NGRAVE hardware wallet
- A separate authentication card (sometimes called the ZENGO card by the company) for seed phrase security
- USB-C and USB-A adapters
- Instruction manual
Unboxing feels cleaner and more minimal than some other wallets, which I appreciate because clutter can increase setup mistakes, especially for newcomers.
Preparing for NGRAVE Wallet Setup
An essential step is to choose a secure location free from distractions and cameras. Hardware wallets are all about self-custody, so any slip-up while initializing could risk your private keys.
I suggest you have:
- A pen and a notebook or a metal backup plate if you want to go beyond paper
- A fully charged smartphone or tablet to run the NGRAVE app
- Patience (the setup isn’t instantaneous, but it’s deliberate for security)
Unlike wallets that require a constant Bluetooth or USB connection during setup, the NGRAVE wallet is designed to be air-gapped, minimizing wireless attack vectors — something I noticed immediately after unboxing.
Step 1: Powering On and Initial Device Checks
Hold down the power button until the screen lights up. The first boot will run some self-diagnostics. The device screen itself guides you with clear prompts, so you won’t get lost.
What I particularly liked: NGRAVE’s screen isn’t just a basic LCD; it’s designed to provide tamper-proof interaction by being touch-sensitive and resistant to side-channel attacks.
Make sure you verify:
- The device is not pre-initialized (it should prompt you to initialize a new wallet)
- The display is clear and free of glitches
Step 2: Creating Your Secure Seed Phrase
Here's where NGRAVE takes a different approach that caught my attention. Rather than displaying a 12 or 24-word seed phrase directly, it uses an interaction with the included authentication card to generate your seed offline.
This is crucial because standard BIP-39 seed phrases can be vulnerable if typed or displayed on internet-connected devices. NGRAVE’s method effectively removes that risk by:
- Creating the seed phrase offline, fully air-gapped
- Using the hardware wallet screen and the NGRAVE card together for verification
The NGRAVE wallet supports the industry-standard BIP-39 24-word seed phrase, which offers strong entropy for long-term security.
Step 3: Writing Down and Verifying the Seed
Once the seed phrase is generated, you’ll need to write it down. This step can’t be rushed or overlooked. Think of your seed phrase like the master key to a safe deposit box — anyone with it can access your crypto without any further authentication.
NGRAVE encourages you to verify each word against the hardware wallet display to avoid typos. Unlike other wallets where you only see the seed once, NGRAVE’s process is designed to let you confirm the phrase methodically by interacting with the device and authentication card.
For extra security, I recommend transferring your seed phrase to a metal backup plate or a similarly fireproof and waterproof medium. Paper can degrade or get lost — and your crypto won’t wait.
Step 4: Setting a PIN
After your seed phrase is safely secured, the next step is to set a PIN on the device. The PIN prevents unauthorized use if the wallet is lost or stolen.
In my testing, NGRAVE requires a minimum 6-digit PIN, entered directly on the device’s secure touchscreen. This means the PIN never leaves the device or gets sent to your phone or computer.
Don’t choose obvious sequences like 123456 or your birth date. Instead, pick something easy for you but hard for others to guess. The device will lock after several incorrect attempts, protecting you from brute-force attacks.
Step 5: Pairing With the NGRAVE App
Now it’s time to connect the wallet with the companion NGRAVE app on your smartphone or tablet. This is necessary for managing your crypto assets and signing transactions.
Unlike hardware wallets that use Bluetooth or USB-C directly, NGRAVE uses QR codes to transfer data — a wholly air-gapped method. Here’s what I found during this process:
- The wallet generates a QR code showing transaction requests
- The phone camera scans this to pick up the request
- The phone then displays its own QR code with the signature, which your hardware wallet scans on its screen
This back-and-forth prevents your private keys from ever touching the internet-connected device, a level of security advantage not many wallets offer without complex workarounds.
Step 6: Firmware Updates and Security Verification
One thing I would never skip is updating your hardware wallet’s firmware right after setup — or anytime there’s a new release. Firmware updates patch vulnerabilities and sometimes add new coin support or features.
NGRAVE’s firmware updates are applied through the app but still maintain air-gapped communication via QR codes. This means you can verify update authenticity without exposing the device to the internet directly.
To verify:
- Check the official NGRAVE website or this site’s firmware update guide for official hashes
- Cross-check cryptographic signatures when prompted
In my experience, this verification step is what prevents many phishing or supply chain attacks. Skipping it could jeopardize all your funds.
Step 7: Using Your NGRAVE Hardware Wallet Daily
Once your wallet is set up, daily usage involves generating unsigned transactions on the app, scanning QR codes to sign them on the wallet, and then broadcasting from the app.
The air-gapped workflow might feel slower than plugging in a USB device or pairing Bluetooth, but the trade-off is reduced attack surface.
Be mindful that the NGRAVE wallet currently supports major blockchains like Bitcoin, Ethereum, and some leading altcoins (details are in our NGRAVE supported coins review). This makes it versatile enough for typical HODLers and active users alike.
Tips for Safe Seed Phrase Management
You probably know this already, but I can’t stress enough: keep your seed phrase offline and never share it.
Key takeaways:
- Avoid digital backups unless they’re encrypted and offline (e.g., air-gapped USB drives)
- Consider geographically distributing your backups to mitigate risks like fire or theft
- Avoid using passphrases (25th word) unless you fully understand the recovery implications — more on this here

Troubleshooting Common Setup Issues
Some users have reported difficulty during the initial pairing or seed phrase verification steps, often due to:
- Poor lighting conditions impacting QR code scanning
- Misplacement or misunderstanding of the authentication card
- Confusion around the air-gapped signing process
If you run into problems, try restarting both the wallet and the app, ensure your device’s camera lens is clean, and double-check the NGRAVE wallet review or common mistakes for further troubleshooting advice.
Closing Thoughts and Next Steps
Setting up the NGRAVE hardware wallet demands a bit more patience than some competitors, mostly because of its air-gapped design and focus on offline seed phrase generation. But I believe this setup approach aligns well with serious crypto holders who want to limit wireless attack vectors and ensure their seed phrase never touches online devices.
If you’re seeking a ledger setup alternative with strong security architecture and unique seed phrase backup methods, the NGRAVE wallet deserves a look.
