Both of these wallets got the first decision right: no altcoins. That's the baseline. Now let's figure out which one actually earns a spot securing your bitcoin.
I've spent time with both devices. I've set them up, signed transactions, tested the firmware. What follows is what I found.
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.
Why Blockstream Jade Plus Wins
Both are Bitcoin-only (good choice either way). Air-gapped operation for maximum security. Virtual secure element with no backdoors.
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.
SeedSigner's Weaknesses
Requires direct connection (potential attack vector). Requires DIY assembly. No commercial support.
Feature Comparison
The specs that matter for Bitcoin security.
| Feature | Blockstream Jade Plus | SeedSigner |
|---|---|---|
| Price | $149 | $50 |
| 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 only) |
| Connection | QR codes (fully air-gapped), Bluetooth, USB-C | QR codes only (air-gapped) |
Under the Hood: Security
The security model is where you should start any comparison. Everything else is just features.
- 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.
- SeedSigner: DIY Raspberry Pi-based signing device. Stateless - generates keys from seed each time.
Open-source on both sides. That's how it should be. Neither wallet asks you to trust a black box. The code is out there for anyone to audit.
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.
The Verdict
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.
What You Pay
SeedSigner costs less at $50, but the $99 you'd save isn't worth the trade-offs. Blockstream Jade Plus earns its price tag.
Who Should Buy Which?
Budget-conscious? SeedSigner 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.
