Two Bitcoin-only wallets. Both refuse to touch altcoin code. That already puts them ahead of 90% of the market. But you're here because you want to know which one deserves your sats. Fair enough.
I've tested both of these wallets and formed opinions the old-fashioned way: by actually using them. Here's what stood out.
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.
How They Compare
The specs that matter for Bitcoin security.
| Feature | Blockstream Jade Plus | Krux |
|---|---|---|
| Price | $149 | $40 |
| Bitcoin-Only | Yes | Yes |
| Open-Source | Yes | Yes |
| Air-Gapped | Yes | No |
| Secure Element | Virtual Secure Element (no hardware SE, but cryptographically equivalent security without the black-box trust issues) | None (software security) |
| Connection | QR codes (fully air-gapped), Bluetooth, USB-C | QR codes only (air-gapped) |
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.
- Krux: Stateless DIY signing device. Similar concept to SeedSigner but supports more hardware.
Both wallets are open-source. Good. That means you can verify the code yourself, or rely on the security researchers who already have. This is the baseline for serious Bitcoin storage.
Blockstream Jade Plus supports air-gapped operation via QR codes. Your private keys never have to touch a networked device. Every USB cable, every Bluetooth connection is an attack surface you don't need.
Why Blockstream Jade Plus Wins
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.
Krux's Weaknesses
Requires direct connection (potential attack vector). DIY assembly required. Less polished UX. No commercial support.
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
You'll save $109 with Krux at $40. But Blockstream Jade Plus's premium buys you real improvements worth the extra cost.
Market Context
Hardware wallets aren't going away. As more people realize exchanges aren't safe, devices like Blockstream Jade Plus and Krux become more important. The question isn't whether to self-custody. It's how.
