Two entry points into Bitcoin self-custody with very different philosophies. The Jade ($79) is traditional self-custody. You control the seed phrase, you're fully responsible, and the device has a display for transaction verification. Bitkey ($250) is assisted self-custody: 2-of-3 multisig with Block holding one key, enabling easier recovery but requiring trust in Block's infrastructure. The current model has an OLED touchscreen. The original had no screen, so you verified everything on your phone.
Buying Advice
Get the Jade. Better price, full sovereignty, on-device verification. If you want an easier UX with more screen space, get the Jade Plus instead of Bitkey.
The Bottom Line
The Jade wins. It is $171 cheaper and involves no third party. Bitkey's recovery model is forgiving, but it requires trusting Block's infrastructure. The Jade requires trusting yourself, which is the entire point of Bitcoin.
Under the Hood: Security
Security is the whole point. Everything else is secondary. Here's how these two handle it:
- Bitkey: 2-of-3 multisig with keys split between hardware device, mobile app, and Block server. Designed for recovery simplicity.
- Blockstream Jade: Virtual Secure Element with blind oracle PIN verification. Same security model as Jade Plus.
One wallet lets you see every line of code. The other asks you to trust their word. Blockstream Jade is fully open-source. Bitkey isn't. For Bitcoin security, transparency should be the default, not the exception.
Blockstream Jade 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.
Feature Comparison
The specs that matter for Bitcoin security.
| Feature | Bitkey | Blockstream Jade |
|---|---|---|
| Price | $250 | $79 |
| Bitcoin-Only | Yes | Yes |
| Open-Source | No | Yes |
| Air-Gapped | No | Yes |
| Secure Element | Secure enclave (chip model not published) | Virtual Secure Element |
| Connection | NFC | QR codes (built-in camera), Bluetooth, USB-C |
The Verdict
The Jade is the best value in Bitcoin hardware wallets. For $79 you get a built-in camera for air-gapped QR signing, open-source firmware, and the same security model as the Jade Plus. The tradeoffs are a small 1.14-inch screen and a plastic body. If you are buying your first hardware wallet, or a backup device for a multisig setup, this is the one I would buy.
What Blockstream Jade Does Better
Best for: Budget-conscious Bitcoiners, Those who want Jade Plus security at lower price, A second signing device for multisig, First-time hardware wallet buyers.
Where Bitkey Falls Short
- Requires direct connection (potential attack vector)
- Relies on Block infrastructure
- Less sovereignty than others
What You Pay
Blockstream Jade undercuts Bitkey by $171 and still wins on the merits. $79 for a better wallet? Easy call.
Market Context
Hardware wallets aren't going away. As more people realize exchanges aren't safe, devices like Bitkey and Blockstream Jade become more important. The question isn't whether to self-custody. It's how.
What People Ask
Is the Jade or Bitkey better for a first hardware wallet?
The Jade. It costs $79 against Bitkey's $250, is Bitcoin-only, and I've used it as my pick for a first wallet. Bitkey is also Bitcoin-only and easier to recover thanks to its 2-of-3 multisig. But the Jade rates 9.0 on my scale to Bitkey's 8.5 and involves no third party.
Is Bitkey worth $171 more than the Jade?
Only if easy recovery and inheritance matter more than price. Bitkey costs $250 and adds a six-month inheritance feature, a 2026 OLED touchscreen, and a recovery path if you lose a device. The $79 Jade has a 1.14" screen, QR signing, and no reliance on Block. For most buyers the Jade is the better value.
Can the Jade or Bitkey sign air-gapped?
Only the Jade. It has a built-in camera and signs by QR code, and I recommend Sparrow over QR for a computer setup. Bitkey uses NFC and needs its mobile app to work, so it cannot run fully disconnected. If you want your keys away from networked devices, choose the Jade.
Does Bitkey or the Jade give me full control of my keys?
The Jade does. You hold the seed phrase and nobody else holds a key. Bitkey uses a 2-of-3 multisig where Block keeps one key. That key cannot spend alone, but recovery depends on Block's servers. Bitkey also has no passphrase support, while the Jade supports passphrases.
