How to buy it?
https://satochip.io/shop/ seems all your products out of stock.
I am preparing to buy, are we have to request a product first, I mean preorder and what payment accepted?

Hey

It's cool to see people ready to buy our products ...
We have finished the Beta Tester phase and the output testers gave us was huge!

Now we are currently printing our cards and collecting stuffs for packaging. That's why I put the website "out of stock" because we cannot provide large quantity right now.
If you want to buy a BTC or BCH card, feel free to reach me in DM (here on BTCTalk) or per mail : [email protected] or even on our Telegram

I would be really happy to deal with you Cheesy

Regarding our expectation to open the shop, I think we will need to wait a few weeks again, just to be sure everything is ready for mass production.

Thanks for your interest.

Updates for the Electrum-Satochip client

📦 We have release the .exe files for the Electrum-Satochip-client in version 0.8 for Windows

📦 And the AppImage format for Linux

Version 0.8 brings new features such :
- you can now change your PIN code
- you can now reset the seed of the Satochip hardware wallet (that means you reset the card, beware not to lost your funds).
- 2FA improvements : when signing a message or resetting the seed, you need to confirm through the 2FA Android app (if enabled).

🌍 Avalaible on :https://github.com/Toporin/electrum-satochip/releases/tag/v3.3.8-0.8

At what point will these be available? I saw the tweet at the end of August saying that there were some available to beta testers on Twitter here: https://twitter.com/SatochipWallet/status/1167109684718899202

I'd be interested in messing about with one and seeing how it works with a mobile device/NFC etc... But the shop always says "Out of stock". Are there any still available for testers? or will I need just be patient? Huh

It will be available very soon. The beta tester program is now over and the only way to get a Satochip wallet is to buy it.
We will open our shop in a few days

Stay tuned !

Big updates

We have released a new version of the Satochip applet, Electron-Cash client and 2FA Android app.

The new release takes into account the feedback received during the beta test phase and should be production-ready.
Thanks to all those who contributed to the improvements! Cheesy

Main changes are:
* Possibility to change the PIN code or reset the seed from the EC client (click on the satochip icon on the low-right corner)
* if using 2FA: signing message and resetting seed now requires 2FA approval
* 2FA can be disabled, only when the seed and all private keys are cleared beforehand.

The new releases are available here:
* Satochip applet v0.8: https://github.com/Toporin/SatochipApplet/releases/tag/v0.8-0.1
* Electron-Cash-Satochip v4.0.11-0.8: https://github.com/Toporin/Electron-Cash-Satochip/releases/tag/v4.0.8-0.8
* 2FA app: https://play.google.com/apps/testing/org.satochip.satochip2fa.satochip2fa

You should always use the EC client version that corresponds to the Satochip applet loaded on the smartcard (e.g v0.7 or v0. Cool

.
Some functionalities may be unavailable or incompatible otherwise.
For example, signing messages requires 2FA approval (if enabled) on the new version of the applet (v0. Cool

but the EC client v4.0.8-*0.7* does not support this.

Important reminder: do not forget to backup your seed and 2FA key (if enabled) !

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.

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

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.

Yes indeed. That's why we focuse on the chip part first. The more interraction you provide, the bigger is the surface attack.
In summury, the card is NFC compliant but the whole hardware wallet procedure (including the client part) isn't.

Let's add it to the roadmap ! Cheesy

Well, the card is NFC compliant and it's recognized by any NCF reader.
So if you have a desktop NFC reader, it would work flawless. With a smartphone, it's another question because of the use of Electrum client.

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

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 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.

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.

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 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.

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

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.

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.

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.

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?)

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

So, if I'm reading this correctly... I need some sort of card reader device to be able to use one of these?

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.

Quote from: HCP on September 06, 2019, 05:34:38 PM

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
