Here's the situation: Blockstream Jade Plus is Bitcoin-only. NGRAVE ZERO supports altcoins. If you've spent any time on this site, you know where I stand on that. But let me walk you through the full comparison anyway.
I've handled both wallets personally. Went through the setup, tested the signing, poked at the edges. Here's what matters.
The Bottom Line
Blockstream Jade Plus is simply the best Bitcoin wallet on the market. Air-gapped, open-source, and Bitcoin-only. It's not even close.
Side-by-Side Comparison
The specs that matter for Bitcoin security.
| Feature | Blockstream Jade Plus | NGRAVE ZERO |
|---|---|---|
| Price | $149 | $398 |
| Bitcoin-Only | Yes | No |
| Open-Source | Yes | No |
| Air-Gapped | Yes | Yes |
| Secure Element | Virtual Secure Element (no hardware SE, but cryptographically equivalent security without the black-box trust issues) | EAL7 certified (highest level) |
| Connection | QR codes (fully air-gapped), Bluetooth, USB-C | QR codes only (no ports at all) |
Security Architecture
Security is the whole point. Everything else is secondary. Here's how these two handle it:
- Blockstream Jade Plus: Virtual Secure Element with blind oracle PIN verification. Your seed is never stored in extractable form. Uses a unique architecture where the PIN, device data, and Blockstream oracle combine to reconstruct the key only during signing.
- NGRAVE ZERO: Air-gapped with biometric and secure element. Premium security features.
Blockstream Jade Plus is fully open-source, inside and out. NGRAVE ZERO technically isn't. This matters more than just about anything else to me. With only "verifiable-source" firmware, no matter what a company says, there's ultimately a small layer of trust still present. Why not let the community gain full access? Open-source means anyone can not just look at the code, but build with it too. Blockstream hosts all kinds of DIY workshops at conferences to showcase the Jade's brutally transparent architecture. I know which approach I trust with my bitcoin.
On Altcoin Support
Every altcoin NGRAVE ZERO supports is code that could compromise your bitcoin keys. Blockstream Jade Plus doesn't carry that weight. Bitcoin-only firmware is leaner and more auditable.
Blockstream Jade Plus's Advantages
Best for: Security-focused Bitcoiners who want verifiable, auditable security, Users who value air-gapped operation without compromise, Those concerned about closed-source secure elements, Bitcoin maximalists who don't need altcoin support.
NGRAVE ZERO's Weaknesses
Multi-coin support introduces unnecessary risk. Very expensive. Multi-coin support. Overkill for most users.
The core issue: NGRAVE ZERO supports altcoins. For serious Bitcoin storage, that's a liability, not a feature.
My Recommendation
The Jade Plus is my top recommendation for most Bitcoiners. It hits the sweet spot between uncompromising security and actual usability. The air-gapped QR workflow is smooth, the screen is readable, and the open-source architecture means you're not trusting anyone's pinky promise. At $149, it undercuts the Passport and matches the Coldcard Q on features while being more approachable. Buy it.
Price & Value
Blockstream Jade Plus undercuts NGRAVE ZERO by $249 and still wins on the merits. $149 for a better wallet? Easy call.
Who Should Buy Which?
If you value a focused, Bitcoin-only approach, go with Blockstream Jade Plus. If a broader feature set matters more, NGRAVE ZERO is your pick. But for pure bitcoin security, I always lean toward the Bitcoin-only option.
