Blockstream Jade Core Review (2026)
The simplest Jade: USB-C, Bluetooth, and a big screen for $99
Disclosure: I work at Blockstream, the company that makes this wallet. I joined the company after many years as a satisfied user.
The Blockstream Jade Core is a $99 Bitcoin-only hardware wallet that launched on April 28, 2026. It has the same 1.9-inch screen and blind oracle security model as the Jade Plus, connects over USB-C and Bluetooth, and runs open-source firmware. It has no camera and no battery, so you cannot sign air-gapped with QR codes and it only runs while plugged into power. If you want air-gapped signing for less money, the original Jade is the better buy.
Blockstream launched the Jade Core on April 28, 2026 as the simplest device in the Jade lineup. Blockstream calls it the off-ramp device: plug it in, pair it with the Blockstream app, write down your seed phrase, and move your bitcoin off the exchange. It keeps the Jade Plus screen and security model and drops the camera, the battery, and the SD card slot. That makes it a good first hardware wallet for someone who will never touch QR signing, and a strange buy for anyone who will.
The Jade Core runs the same Bitcoin-only firmware as every other Jade. Blockstream says all three devices run identical open-source firmware. It handles Liquid, Blockstream's Bitcoin sidechain, and no altcoins. Less code means fewer bugs, and that is the whole point of a Bitcoin-only device.
Blockstream Jade Core price in 2026
Blockstream's store lists the Jade Core at $99, and Blockstream's June 2026 lineup post says it ships free worldwide. The original Jade lists at $79 and was on sale for $67 in October 2026. Blockstream's lineup post puts the Jade Plus at $149 and up.
Buy it directly from Blockstream's store rather than a third-party marketplace. Genuine Check will confirm the device came from Blockstream during setup, but buying direct means nobody else handled it first.
What the Jade Core leaves out
Blockstream's own comparison chart marks the Jade Core with no camera, no battery, no SeedQR, no stateless QR signing, no air-gapped transactions, and no air-gapped firmware upgrades. The Jade Plus has all of them, plus SD card and USB drive support.
The missing battery changes how you use it. Blockstream's setup instructions say to power the Core with a USB-C cable, then pair over Bluetooth. Using it with your phone means plugging it into a wall adapter or power bank first.
How the Jade Core keeps your keys safe
The Core uses the same blind oracle PIN model as every Jade. Your PIN unlocks a secret that is split between the device and a remote oracle server that never sees your keys or your PIN. Blockstream says there is no physical secure element, so there is nothing of value to steal from a locked Jade by itself.
Blockstream runs the default oracle, and you can run your own. The hardware and firmware are open source, and Genuine Check lets you verify during setup that the device came from Blockstream. Blockstream also lists anti-exfil protection and passphrase, duress PIN, and 2FA support in the firmware.
Jade Core vs Jade vs Jade Plus
All three run the same firmware and the same security model. The Jade Core and Jade Plus share the same 65 x 30 x 12 mm body and 1.9-inch, 320 x 170 screen. The Jade Plus adds a camera, a battery, and SD card support and starts at $149. The original Jade costs $79 and keeps a camera and a battery.
Buy the Jade Core if you want the bigger screen and will only use a cable or Bluetooth. Buy the original Jade if price and air-gapped signing both matter. Buy the Jade Plus if you want everything.
Wallet apps that work with the Jade Core
Blockstream lists the Blockstream app on Android (Bluetooth and USB-C), iOS (Bluetooth), and desktop (USB-C). It also lists Sparrow, Electrum, Nunchuk, BlueWallet, and HWI. Sparrow over USB-C is the setup I would use on a computer.

About Blockstream
Trust Assessment
Reasons to Trust
- Same security model and firmware as Jade Plus
- Fully open-source hardware and firmware
- Genuine Check device verification at setup
- Same 1.9" screen as Jade Plus
- Bitcoin and Liquid support
Concerns
- No camera, so no air-gapped signing
- No battery: needs USB-C power even over Bluetooth
- Default PIN oracle is run by Blockstream unless you host your own
- Launched in April 2026, so it has a short track record
Where It Shines
- Jade Plus Screen for Less: The Core has the same 1.9-inch, 320 x 170 screen as the Jade Plus, which makes checking addresses easier.
- Same Security Model: Blind oracle PIN protection, Genuine Check, and the same open-source firmware as every other Jade.
- Simple Setup: Plug in over USB-C, pair with the Blockstream app, and write down your seed phrase. Blockstream built it for people leaving an exchange for the first time.
- Open-Source: Blockstream says the hardware, firmware, and security model are all open source, so anyone can audit them.
What Could Be Better
No Air-Gap
With no camera, every transaction is signed over a USB-C cable or Bluetooth. QR signing and SeedQR backups are off the table.
No Battery
The Core needs USB-C power to run. Pairing with your phone over Bluetooth still means plugging it into a power source.
Priced Above the Original Jade
At $99 it costs $20 more than the $79 Jade, which has a camera and a battery.
Security Incidents & Controversies
Every company makes mistakes. What matters is how severe they are and what they reveal about priorities. Here's Blockstream's track record:
Blockstream released Jade firmware 1.0.41 with security fixes found by outside reviewers, stronger stack protection, extra per-device entropy for seed generation, and downgrade protection, and told all users to upgrade. The Jade Core runs the same firmware as every Jade, so this applies to it. The earlier DARKNAVY descriptor flaw was fixed in 1.0.37 and 1.0.38, before Jade Core support arrived in firmware 1.0.39.
Best For
- First-time buyers moving bitcoin off an exchange
- Blockstream app users who will never use QR signing
- People who want the Jade Plus screen without the Jade Plus price

My Final Take
The Jade Core is a solid hardware wallet for someone moving their first bitcoin off an exchange. You get the Jade Plus screen, Genuine Check, and the blind oracle PIN model for $99. You give up the camera, which is the feature I value most in the Jade line. Without it there is no air-gapped QR signing, and without a battery it only runs on USB-C power, even over Bluetooth. The original Jade costs $79 and has a camera. If you will only ever use the Blockstream app on your phone, the Core is fine. If you care about air-gapped signing, buy the Jade or the Jade Plus.
