Hello Smiley

There is a new hardware wallet in town : Satochip
Maybe the very first affordable and open source hardware wallet in the world !



----------------------------------

Satochip stands for Secure Anonymous Trustless and Open Chip.
Similarly to your bank card, it is a javacard applet that can be used as a small form factor and secure hardware wallet.

This card :

- is super cool  Cheesy
- has a low-form factor
- is wheater resistant
- embeds a quality and open source code
- supports several cryptocurrencies such as Bitcoin and Bitcoin Cash
- can be used with the Electrum client

----------------------------------

Currently, the team is focused on the coin integration. So far, we support :

- Bitcoin through the use of Electrum Bitcoin client (with the Satochip plugin)


- Bitcoin Cash through the use of Electron Cash client (natively supported since v. 4.0.11)
- Bitcoin Cash SLP token through the use of Electron Cash SLP version (natively supported since v. 3.6.1)


- Litecoin through the use of Electrum Litecoin client (with the Satochip plugin)


----------------------------------

It's certainly affordable. Few thought/question :
1. Don't forget to mention your GitHub website on this thread
2. Do you have documentation for regular user? At first i thought this HW wallet uses wireless connection until i read technical specifications.

Anyway, while it's interesting wallet, i wouldn't use it until it's more popular or has passed security audit (CMIIW if it already happened).

Hey  Cheesy

I have just add our GitHub repository.
We do have a documentation for regular user that we send each time it is asked.

Basically, the use of this hardware wallet is super simple if you know how to use Electrum Bitcoin client.
The only thing we have added (client-side) is the plugin to detect our hardware wallet.

Regarding the Electrum-Satochip client, we have send some cards and our code to the Electrum team in Berlin to get a feedback.

The code wihtin the chip is open-source so anyone can check it.

I will post here any information needed if you want.

Cheers.

It'd be great if you share the information here. I'm sure other members will ask same question/request eventually.

I was interested to order one but It says the card is out of stock and available on request only.
Are you still in Beta phase? (I saw that there was a card for beta testers) When do you think you'll have new stock so. (or it's only on request?)

Quoting for the images.

So, we need a card reader to use this wallet? I'm not sure what is this and where someone would get one.

So, if I'm reading this correctly... I need some sort of card reader device to be able to use one of these? And also I would need to use a custom, modified version of Electrum? Huh

Or is it just an Electrum plugin?

I've looked around and it's probably something like this: https://www.amazon.com/slp/chip-card-readers/a4mttkzjrotw723 which costs $12~$32.

And also I would need to use a custom, modified version of Electrum? Huh

Yes. At least for now.

They made a pull request on Electrum's repo for their plugin: https://github.com/spesmilo/electrum/pull/5533

Yes, the website already mention you need USB 3.0 SIM/EID card reader which is turn-off since total costs to use this wallet is almost doubled.

Chip & connector

    Chip : NXP JCOP J3H145
    Connector : USB 3.0 SIM/EID card reader (optionnal)

Yes. At least for now.

Looks like it'll take a while, there's no reviewer or assignee.

I see lack of information, instructions or FAQ page on your website for 'how to use the wallet'
That makes it unusable for any newbie that wants to buy his first hardware wallet.
Maybe you should improve and add this.

It looks interesting. I haven't used card readee, so I don't know how exactly it would work with hardware wallet. Is it at least convenient? And, yeah, your hardware wallet is very cheap, but people would need to buy card reader too, what is disadvantage - I doubt that many people have such thing at home.
And I miss more detailed information on your website. Also, it's written that this hardware wallet is out of stock and ther is no information about shipping, payment options and etc.

Hello,

Yes, we are currently in Beta phase. We have achieved our third tests run successfully and now are ready for production use.
I'm in contact with our card provider and card printer to finalize the first production batch.

When all these details will be sorted out, we will officially open our webshop.

So stay tuned  Cheesy

Yes, our hardware wallet is based on a javacard with a secured chip the same used by bank companies.
This card is NFC compliant. So you can either use a card reader or a NFC reader on your computer.

For information, here in Belgium, card readers are common because we use it to pay our taxes online (we have to put our ID card to authenticate ourselves).
So almost every Belgian users have such device "whoop whoop".

I think almost every Estonian have one too  Grin

We plan to sell card readers in our webshop but first, let's focus on the main product : the Satochip card.

Thank you for your feedback.
You are not the first one that point the lack of information regarding how to use the Satochip hardware wallet.
But ... (yeah, there is always a "but"  Grin)

But this is very very easy to use.
If you know how to use Electron (or Electron cash for BCH support), you will set up your Satochip card in a minute.

Basicly, the Satochip card only works with :
- a card reader
- Electrum Satochip or Electron Cash Satochip

You plug the card, launch the client, setup the card and use it everytime the card is plugged.
Let me update the website, of at least add a FAQ or a tutorial page with all the information.

By the way, when you purchase a Satochip card, we send you a step by step guide on how to use the card  Smiley

As said, we will sell card readers in our webshop at a very good price (less than 10$). The use of such device is really really easy. Just like your bank card, you have to plug the card in the reader, open the client, put your PIN code and you are ready to use it ! We made it super simple to use !

Regarding the shipping cost, we send the card worldwide for free through normal letter.

We have already send cards around the globe :
- Belgium : you get the card the next postage day
- Europe : you get the card after 3-4 days
- United States : it took 3 weeks but arrive with no problem.

For big quantity, we might send with insurrance.

I really like the idea here, but I have some questions:

Does one card represent one private key?  How are the keys generated?  Is it a hierarchy deterministic wallet, and if so do you initiate the wallet with a seed created by the Electrum client?

You'll have to excuse my ignorance and skepticism, but I'm not a technical guy so I wouldn't be able to scrutinize the code for anything malicious.  Have you had a trusted third party audit the code?

No one is ignorant when he asks questions !
And about your skepticism, this is totally normal as we are speaking about hardware wallet, key generation, crypto-currencies, ...  Wink

The Satochip card can handle only one seed and all the keys are derivated by the chip. The seed is created by the Electrum client : yes. It would consume too much computer power to do it on the chip side.

"Have you had a trusted third party audit the code" -> We make it open-source so the entire world (and you) can check and audit the code. We also have submitted our code to the Electrum dev team for review.
We strongly encourage everyone who is attracted by this project to review our code on https://github.com/Toporin

Regarding the Electrum client itself, we have add the plugin to recognize the Satochip.
The applet is a custom dev and hence, should be audited.

Thank you for your support.

Have any tests been done (or are any planned) with NFC capable smart phones (and perhaps a modified Electrum client)? Huh

Learn something new every day... was not aware that card readers were so widely used within the general populace anywhere to be honest!

Would be interesting to see a video of the test. I'm pretty sure any NFC capable smartphone would be able to detect it, but the Electrum part needs some testing, especially the security part. Wouldn't be fun if a bug exist and allows the user to spend without connecting the card to their device.
