I saw you are offering interesting new Satochip blank card in form of SIM card for making our own hardware wallet with Satochip code.
Huh, that
is interesting! I was just playing around with my Satochip when I decided to check out the HW wallet section to do a little research on it after the Ledger debacle, and I came across this old thread. The SIM format is probably over my head, but I do like the newer products coming out from the developers of the Satochip.
By the way Tibu, this question was never answered and I'm curious about it myself (though I don't recall ever reading that on the Satochip site:
"The Satochip hardware wallet has full BIP32 and BIP39 support and also supports the import of regular (non-BIP keys) such as vanity keys. Even more, private keys cannot be exported outside of the secure chip. Up to 16 regular keys can be imported on the chip. "
What does it mean? You can import into Satochip single private keys which were exported from, say, Core?
One by one?
One other thing that I hope isn't too far off-topic: As I was reading the description of the DIY SIM wallet I noticed that it's badly in need of some editing. As an example:
You want to upload your own firmware (Satochip, Satodime or Seedkeeper) but wants to use the smallest form factor as possible ?
That's sloppy English, and I always say if you're going to be writing English on a website it better be flawless (or as close to it as you can get). You've got a space between
possible and the question mark for some reason, and that's in addition to the incorrect form of
want. Isn't this much better:
You want to use the smallest form factor possible when using the Satochip, Satodime, or Seedkeeper firmware? We've got you covered with a compatible javacard, pre-cut into a SIM card-sized chip.
Yeah I'm a grammar Nazi, but when I see pages like that and the writing is....bad (sorry, just giving it to you straight)....it's a turnoff, even if I like your product very much. If you ever want some editing done, I'm cheap but thorough.
Boy, I missed that link altogether when you posted it, and I'm going to check it out now. One of the reasons I was browsing this section for Satochip info was to get answers to some of those same questions.
Sorry for the delay. I'm not very often here.
Regarding the keys import, your previous assumption regarding Electrum was right. In fact, you can importe BIP39 seedphrase but also other type of seed. Maybe we should rephrase this to be more clear.
You are right, we should be more careful with English translation. This one is way better. Thank you!
