How about secure elements? Is any of these SoCs protected against just reading out its flash contents through a debug port or desoldering a flash chip from the PCB?
Odudex can correct me if I am wrong, but I think everything is erased from Krux once you turn the power off, so there is nothing to read and copy.Than you have to load seed phrase each time you turn the power on, best with QR code scan, but it can be done manually.
That is why we don't need to have or trust secure elements, and one of the reasons I like Krux.
Glad to see it, though.Unfortunately, keeping a QR code with me and making sure nobody takes a picture of it etc., does not fit my usage model for such a device at the moment.
