Blockstream Jade Plus runs Bitcoin-only firmware. Tangem decided to support altcoins too. One of these approaches is correct. But I'll lay out the full picture so you can see for yourself.
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.
Side-by-Side Comparison
The specs that matter for Bitcoin security.
| Feature | Blockstream Jade Plus | Tangem |
|---|---|---|
| Price | $149 | $70 |
| Bitcoin-Only | Yes | No |
| Open-Source | Yes | No |
| Air-Gapped | Yes | No |
| Secure Element | Virtual Secure Element (no hardware SE, but cryptographically equivalent security without the black-box trust issues) | Samsung S3D350A |
| Connection | QR codes (fully air-gapped), Bluetooth, USB-C | NFC only |
Security Architecture
Let's get into what actually matters: how these wallets protect your bitcoin.
- 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.
- Tangem: NFC smart card with secure element. Simple but limited.
Blockstream Jade Plus is fully open-source, inside and out. Tangem 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.
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.
On Altcoin Support
Tangem supports altcoins. Every line of altcoin code is code that could have a vulnerability. It's code that doesn't serve your bitcoin. Blockstream Jade Plus is Bitcoin-only: focused firmware for a focused purpose.
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.
Where Tangem Falls Short
Multi-coin support introduces unnecessary risk. Requires direct connection (potential attack vector). Multi-coin support. Limited security features. No screen for verification.
The core issue: Tangem 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
You'll save $79 with Tangem at $70. But Blockstream Jade Plus's premium buys you real improvements worth the extra cost.
Who Should Buy Which?
Budget-conscious? Tangem costs less. Security-focused? Go with Blockstream Jade Plus. New to self-custody? Either will work, but start with the one that keeps things simple.
