Okay, so here's my top tip right off the bat - plug in your NGRAVE Zero and let it charge up completely before you touch anything else. Why? Because setup takes like 20-30 minutes, and if it dies mid generation, you're screwed. In my experience, that little USB C port under the cover fills up fast, but low battery warnings pop up at the worst times. Trust me, I learned this the hard way once.
Grab the cable from the box, pop off the side cover, and juice it up. You'll see a charging indicator. Done? Unplug and power on with the side button. Super short sentence. Boom.
You got the Zero device itself - that sleek black air gapped beauty with the EAL7 certified chip. No Bluetooth, no WiFi, nothing connecting it to the evil internet. Then there's the GRAPHENE plates if you splurged on the combo - those stainless steel bad boys for punching your backup. Recovery paper as a temp option. Some quick start cards, USB cable, and that's it. Minimalist AF.
The thing is, don't toss the box yet. Keep it for warranty stuff. Now, power on. Screen lights up, pick your language - English usually, unless you're feeling fancy. Hit next.
Why does this matter? Hackers love supply chain attacks. This checks yours is legit from the factory.
Now set your 8-digit PIN. Make it strong - not 12345678, idiot. Enter it twice to confirm. Short and memorable, but tough to guess. In my experience, I use a combo of birth year and random numbers. Works.
Then fingerprint. Rest your finger on the back sensor. Follow the swipes - up, down, sides. It'll say "Fingerprint registered - can unlock and sign txns now." Cool feature. But enable it in settings later if you want. Fingerprint's optional but highly recommended. Faster than PIN every time.
What's next? "Choose your wallet" screen. Pick Create a wallet. (Import later if you got one.)
This is where NGRAVE shines. No pre generated seeds from shady factories. It makes your right there, offline, using internal chip randomness plus your fingerprint. You interact to prove only you know it.
First, it generates a bunch of groups. Freeze some values - tap to freeze/unfreeze a few times. Hit next. Then pick groups of 8 characters and shuffle them. Repeat as much as you want. Shuffle mixes it up, ensuring no one else - not even NGRAVE - can reconstruct your full.
Finally, boom - your 8 unique keys (like alphanumeric strings, one per slot). Memorize or note nothing yet. Backup next. This whole thing's air gapped. No internet snoops.
Don't skip this. Lose your Zero? No backup = lost funds forever. GRAPHENE's the pro move - stainless steel plates, fireproof, punch holes for each character.
GRAPHENE Steps:
Paper option? Write each carefully, double check. But paper burns, gets wet. GRAPHENE's forever. I always go GRAPHENE. Costs extra but worth every penny.
Potential issue: Punching too hard? Plates are tough stainless. Use the tool. If stuck, wiggle gently. Done right, lasts lifetimes.
Okay, backup secured. Now swipe through coin list. Tap to add BTC, ETH, SOL, USDC, whatever. Or hit + to search. Supports thousands - even NFTs on ETH/Polygon.
I usually add top 10 first: Bitcoin, Ethereum, Solana, USDT, etc. You can add more later. Hit next when ready.
Short para: Don't overload. Start small. Gas fees vary - ETH ~5-20 gwei nowadays, SOL like 0.000005 SOL per tx. BTC network fees ~1-5 sats/vB. Check app later for real time.
Last setup step. Zero shows QR code #1. Scan with phone camera - takes you to App Store/Google Play. Download NGRAVE LIQUID.
App's fire for real time prices, no private keys exposed. Sound familiar from other wallets? But here, fully air gapped signing.
Setup done? Update firmware NOW. Go to Settings > About > Update.
Needs computer: Windows/Mac/Linux. Download updater from Zero's QR/prompt. Plug in via USB (air gapped still, just for update).
Post update: Add more coins if new ones unlocked, like ABX or Polygon. Resync app. Boom, latest security patches. I do this monthly. Firmware adds coins, fixes bugs. Critical.
Issue: Updater fails? Check cable, drivers. Restart PC. Still? Support ticket, but rare.
Ready to load it up? On Zero or app: Pick coin > Receive. Shows address/QR.
Copy address. Send small test amount first from exchange (KuCoin, Coinbase, whatever). Like 0.001 BTC or 10 USDT. Confirm on blockchain explorer after 3-6 blocks.
| Coin | Typical Test Amount | Network Fee Est. |
|---|---|---|
| BTC | 0.001 BTC | ~$1-3 |
| ETH | 0.005 ETH | ~$2-5 |
| SOL | 0.01 SOL | ~0.000005 SOL |
| USDT (ERC20) | $10 | ~$3-10 |
Why test? Wrong network = lost funds. Always match: BTC on BTC, not BEP20. App warns, but verify.
Sending's where air gapping shines. In LIQUID app:
Fees auto suggested. Customizable sometimes. High fee? Faster confirm. Low? Cheaper, slower.
In my experience, first send feels weird - two QRs? But secure as hell. No keys leave device. Hackers can't phish it.
Pro tip: Always verify full tx on Zero screen. Addresses scrollable. Never trust app alone.
Dashboard > Add coin. Search anything supported - 2000+. Post firmware, even more.
Got old 12/24-word seed? Import mnemonic. Zero converts safely. Or import NGRAVE from GRAPHENE/paper.
Steps for import:
But honestly, start fresh for max security. Old seeds risky if compromised.
Unlock: Fingerprint fastest. PIN backup.
Portfolio view in app - real time prices, graphs. Sync often.
Swaps? Not native, but send to DEX like Uniswap via app prep.
Freeze device? Settings > Lock. Or factory reset (loses nothing if backed up).
Traveling? GRAPHENE splits: plates in carry on, Zero checked? Nah, keep together or split sites.
One para on security: Never enter seed online. GRAPHENE can't be digitally copied. Perfect's unique - not standard BIP39, so other wallets can't import easily without conversion.
Fingerprint fails? Clean sensor. Re register.
App sync error? Restart both. Check permissions.
Forgot PIN? 3 wrong tries wipes - but backup restores. Scary but secure.
No coins showing? Resync. Add manually.
Funds not appearing? Check explorer. Wrong chain? Recover via support or fork monitors (rare).
Honestly, it's rock solid. I've run 50+ txns, zero issues. Community forums if stuck.
Check updates monthly. Same process.
Backup verification: Quarterly, punch a test GRAPHENE, verify on Zero.
Add passphrases? Not directly, but multi account via derivations.
