🔥Satochip🔥 Hardware wallet on smart card (USB/NFC)

[The Sceptical Chymist]

What does it mean? You can import into Satochip single private keys which were exported from, say, Core?
One by one?

OK, y'all know I'm no expert here but I've tried the Satochip and it basically just uses Electrum, so if you've got a private key you can import it into the version of Electrum they use (which was outdated when I used my Satochip) just like any other version.  Somebody correct me if I'm wrong, but I think it's that simple.

What's not simple (or rather convenient) is having to use that card reader, but that's another story.

Hi, I am the creator of a website where I compare more than 30 different hardware wallets, feature by feature: https://wallets.thebitcoinhole.com/

I am adding Satochips to the site but I have some doubts about its features. Maybe here someone can help me to clarify them.

1- Does Satochip has any supply chain/physical attack protection?
2- The firmware inside the Satochip can be upgraded? How?
3- Does Satochip has passphrase support? How?
4- Given that Satochip can be connected with thirdparty apps like electrum, this means that it supports features like multisig, coin control, custom node and testnet?
5- Is any kind of user added entropy when generating the private key?

Thanks

Electrum news
Satochip's PR to be natively integrated
-----------------------------------------------------------------------------------------------------------------------------------------------------------------

Satochip works in conjunction with open-source, lightweight software client. Why ? Because no need to reinvent the wheel when something already perfectly works.
That's the case with Electrum (https://electrum.org/), the most used #Bitcoin SVP client.

We have made a new PR to ask the Electrum team to accept Satochip as a natively integretad hardware wallet.
Check this out: https://github.com/spesmilo/electrum/pull/8453

Make your voice count and help us spreading the good words.
A retweet of this would be really appreciated: https://twitter.com/SatochipWallet/status/1662000728330715136?s=20

Thank you.

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

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.

[The Sceptical Chymist]

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. 

We already had a talk recently but I will provide a detailed explaination for everyone.

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.

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.

Tibu, the site you linked to is hard to navigate at best, because with the two browsers I used the horizontal scroll bar disappeared--but aside from that, where exactly is that conversation you referred to?

Also:

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.

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!

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.

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?

Sparrow is probably one of my favorite bitcoin software wallets, right next to Electrum wallet.

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.

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?

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.
