There's no such thing as a sovereign hardware, as even FOSS projects depend on chips from corporations. Best we can do in search of sovereign solutions is make software simple and flexible enough to run on multiple hardware, like Bitcoin does. Supply chain security is a thing.

Maix Cube price lowered, I thought it deserved a port.
It has the screen of a Seedsigner(same size and resolution), buttons of a Jade, and is now receiving a Krux soul.
Comes ready to use, with battery.
Besides being cheaper, IMO Amigo's UX with touch, big screen is MUCH better

Krux running on a tablet likely has the friendliest UX for teaching children and seniors about self-custody and air-gapped transactions.
Roll dice, encrypt a mnemonic, setup a coordinator, and sign transactions without tiring fingers and eyes. 😄

About Cold Card, please read the article:
"TL;DR They didn’t get the master secret out (your Bitcoin seed)"
I don't like SEs, think is mostly a marketing thing, but guys, take it easy and don't play dirty. It's bad for your business and for Bitcoin.
Coinkite presented the results on their blog blog.coinkite.com/donjon-fau…
To give a precision, the seed can be practically extracted if an attacker combines our two attacks in SE2, SE1, and the MCU. You can find the two attacks:

I can use Sparrow to sign a transaction with two different devices. Then, by comparing the signed transactions in Meld or Excel, I can assert that both used RFC6979 deterministic nonces. Is this a bad idea? Should proprietary protocols be used instead of open standards?I hope not

How cheap can a signer be? This "digital magnifier" costs $10. It would require the camera sensor to be replaced, which could add another $4.
The problem is: What's that chip? They even erased the overlay with a laser.
For now, it will keep being a cool toy for me and kids 😁
