Blockstream Jade Plus

Blockstream Jade Plus is a Bitcoin and Liquid hardware wallet built by Blockstream, one of the longest-standing engineering teams in Bitcoin. It is fully open source, and builds on the original Jade with a larger, brighter screen, a metal body option and support for USB drives and SD card readers.

What Jade Plus adds over the original Jade

• Upgraded camera (GC0308, 640 x 480) for faster QR scanning, plus air-gapped firmware upgrades from a USB drive such as JadeLink
• 280 mAh battery, so it works untethered, like the original Jade
• Metal body option and a screen Blockstream describe as 66% larger and 25% brighter
• Four ways to connect — USB-C, Bluetooth, QR and SD card
• ESP32-S3 chipset for faster performance

How Jade Plus secures your keys

Jade Plus does not use a physical secure element chip. Blockstream instead built a virtual secure element using open-source blind oracle encryption, which keeps the device fully open source while preventing physical key extraction. In their words, there is nothing of value to extract from the device itself.

That is a deliberate design choice: secure element chips are proprietary and cannot be fully audited, so Blockstream chose transparency instead. It is a different security philosophy, not a weaker one — and it is the reason Jade Plus can claim to be fully open source.

• Genuine Check hardware attestation and Secure Boot
• SeedQR support, multisig and Miniscript
• Optional stateless use — the device can hold nothing at rest

Bitcoin and Liquid only

Jade Plus supports Bitcoin and Liquid assets, and no altcoins. Less code means fewer places for something to go wrong, and the firmware is written by people who work on Bitcoin infrastructure full time.

• Also works with Sparrow Wallet, Electrum and HWI

Common questions

Metal or plastic?
Black (Plastic) has a plastic body and weighs 25 g. Every other color, including Black (Metal), has an aluminum alloy body and weighs 30 g. The electronics and security model are identical.

Does it have a secure element chip?
Not a physical one. Blockstream use a virtual secure element built on open-source blind oracle encryption, which is what allows the device to stay fully auditable.

Can I store Ethereum?
No. Jade Plus is Bitcoin and Liquid only, by design.

How is it different from the original Jade?
A screen 66% larger and 25% brighter, a metal body option, the faster ESP32-S3 chip, Genuine Check, and air-gapped firmware upgrades and transactions through a USB drive or SD card reader plugged into the USB-C port. The original Jade already has a camera and a battery. The original Jade remains supported and is the more affordable option.

Can I use it with an iPhone?
Yes, over Bluetooth with the Blockstream app.

ONE RULE TO REMEMBER

Anyone who asks for your recovery phrase is a scammer. No exceptions.

Neither SIAMBC nor Blockstream will ever ask for it, whatever reason is given — warranty claims, identity verification, system updates or account recovery. Those words are the key to your funds. Whoever has them owns your crypto, and it can never be recovered.
