Didn't you saw Satochip already released and offered very interesting limited edition cards with Bitcointalk and The Times Newspaper designs? Cool

I saw that yes. I mean it would be cool if I could upload an image and get my own personalized Satochip Hardware Wallet (as long as the image is legal, of course)

Edit:

I was confused about your product descriptions at first.

Satochip is the spending card
Satodime is the (cold storage) hodl card
Satokeeper is the seed phrase store

Do you have custom designs as well?

We worked together on this custom design cards and there is a chance for something new to be released if there is enough interest shown.
Basically, almost any design can be made if enough cards are ordered.

That is amazing. Congratulations to your team and to Sparrow Wallet. You have done a phenomenal job ever since I have been following your topic.

Edit. I have questions. I keep reading that the code within the chip is Open Source. Is the chip itself Open Source too? And what is the worst thing that can happen if I fly out of my country with a Satochip card in my pocket that gets seized at the destination airport?

Hello

Thank you for the kind words. It boosts us.

The code loaded into the chip is open source, yes. And available here: https://github.com/Toporin/SatochipApplet/releases
The chip itself is, in the other hand, closed sources. We use NXP chips... Unfortunately, there is NO fully open source secure element on the market - yet. We are eagerly waiting the Tropic' chip from Satoshi Labs.

Nothing... First of all, Satochip's products look like a bank card. It's hard to say this is a hardware wallet.
Even if someone seized it, the worst he can do with the card, is blocking it after several wrong PIN attempts.

Hey @Tibu
I saw you are offering interesting new Satochip blank card in form of SIM card for making our own hardware wallet with Satochip code.
If anything happening if this SIM card is entered in old smartphone, or we still need to use card readers and laptops for this card?
And is there any other difference compared with other Satochip products?

I think this is very cool idea Cool

https://satochip.io/product/satochip-diy-and-developers-card-sim/

Hey,

Sorry for the long-delayed reply...
Yes, you will need a chip card reader or a sim reader to read the chip. In fact, the phone SIM reader could be enough but I doubt you will be able to interract with it directly from a computer and there is no specific mobile phone application to allow such a use.

Wink

But what about notebooks with a build-in SIM card slot? I think they need a special driver to interact with Satochip SIM card , is this correct?

I have 10 years old HP Ultrabook with a SIM slot but don't know where can I get such driver either for Windows or Ubuntu to try your product.

Any "SIM" card reader should work. Your 10-years old HP laptop can be perfect as long as you have the driver that comes with.
We do not provide any specific driver as our reader are not thight to Satochip project. You can use any standard chip card reader.

On Linux, the easiest way to get rid of the reader is to install the pcscd driver. It does the job.

Code:

sudo apt-get install python-usb pcscd
sudo systemctl enable pcscd.service
sudo systemctl start pcscd.service
sudo systemctl status pcscd.service

But on Windows, it can be painful. Try the generic one that comes with Windows when you plug a SIM card into the SIM reader. It might work out of the box.

Happy to help.

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:

Quote from: Gorilla22 on October 18, 2022, 08:13:54 AM

"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:

Hello,

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.

I have update the SIM product page: https://satochip.io/product/satochip-diy-and-developers-card-sim/
You are right, we should be more careful with English translation. This one is way better. Thank you!

It might not be the most important question in the world, but it'd be nice if you took some time and replied and did so in a manner that doesn't make the other party just sit there and scratch his head. Just saying.
