Yes, we are speaking with Nunchuk to integrate it!

Yes the price point is a bit higher than the Satscard (although also a lot lower than many other hardware wallets), but since it's an on-chain wallet I think it's reasonable considering it will be used to secure multiple tens of thousands of dollars.

You mean the TAPSIGNER I believe, not the SATSCARD.

We were trying to find a name that would be somehow related to the technical functioning of the device (you know, nerds...)

We started from the frequency at which NFC operates, which is 13.56 MHz, but thirteen-fifty-six was a bit too long. So then we did the inverse (which is the wavelength) and it turned out to be around 22 meters.

22 is also 21 + 1, which is kind of cool and on top of this there's also a personal reason which makes 22 a special number for me.

So we just decided to go with it

In general I spend my time building/hacking on anything, whether it's software, electronics, physical things (I like to design stuff and 3D print them!), I even like chemistry and I enjoy watching YouTube chemistry videos.

I also enjoy walking/hiking, I try to walk at least one hour every day (living in a beautiful Italian city helps with that)

Because most people nowadays only have smartphones, and even when they do have laptops they tend to feel more comfortable with mobile devices.

I do this myself too, if I'm at home sitting on the couch I'll just take use my phone to watch a YouTube video or check Twitter StackerNews.

We wanted to build something that would be more comfortable and more accessible to non-technical people, and we believe smartphones are the way to achieve that.

Yes, the backup is a standard BIP39 mnemonic.

And yes you can restore an existing mnemonic on a new Portal, or in any other hardware/software wallet since it's just a standard format.

I think our device is quite unique because it maintains the same security model of "traditional" hardware wallets, while bringing the convenience of using it natively with a smartphone.

It's true that there are many other devices on the market, but most of them can't do what we do. The closest competitors, the other "mobile-native" devices, lack a display, so they are not as secure as Portal because the user can't double check address and amount before confirm a transaction.

That will mostly be up to the wallets which integrate Portal: our device is built with BDK, so we can support singlesig, multisig and complex descriptors (although some functionalities are not yet exposed in the firmware).

The apps can then build whatever user experience they want on it, taking advantage of the features we expose.

Unfortunately we can't replicate a UX similar to FrostSnap because only one device can be powered at a time.

Maybe a mobile wallet later on, but at the moment we just want to focus on the hardware

Our device is priced at 89.00 EUR, which is around 95-99 USD at the moment

The Blockstream Jade wallet is already under this price point (USD/EUR)

We are bootstraping the production right now, we think we'll be ready to ship in the summer. We are committed to shipping within Q3, but we may be able to beat that

Yes!

We have lots of ideas, but they will have to come at the right time. I want to revisit the lightning card for example, but right now it's too early: people don't perceive the value of the added security because lightning is still for pocket change.

Once on-chain fees go up and drive users to other scaling layers we will work on security devices for these solutions as well.

Thanks! We'll see, we have lots of ideas for the next version :)

I think the job was very interesting but ultimately it wasn't for me, I was not completely satisfied and so I decided to leave.

I did not work side-to-side with Adam but we spoke a few times. I'm not completely sure about this but I may have been the first person demo-ing him a Jade signing a transaction with Green

On the hardware side there are no options or menus, it'll just show the mnemonic and you write it down. Obviously the user will need help understanding what's going on, and this will be provided by the app on the phone. But in general we are trying to minimize options/choices as much as possible, we just guide the user through the process without asking too many technical questions

It's a 0.96" monochrome OLED display.

There's no concept of apps on our device because it's bitcoin only. It's not like Ledger on which you install different app based on the coin you want to use.

I don't understand what you mean with the camera question, can you rephrase it please?

I don't unfortunately, I tried it at the beginning and it wasn't working very well so I kind of gave up. I should try it again, I'm sure it's improved a lot over time

We called it Portal because it sounds cool. I was talking about it with some friends and one mentioned that the hole made it look like a Portal out of a sci-fi movie, and the name stuck.

Nothing specific planned yet, we just have a bunch of ideas to develop.. we will also make decisions based on user feedback on this first version

Have you ever had Giacomo Zucco here? I think he would have a lot of interesting things to say!

I don't love sugary drinks (although I like them more than alcoholic drinks), but if I had to choose I would probably pick Pepsi

I don't think I have any particularly weird beliefs, but the thing that probably makes me stand out a bit from most other developers or people working in the industry is my lack of interest for all the "new cool tech".

It's not that I think it won't work, far from it, but I just like to focus on more tangible things, stuff that can be built today.

This means I'm completely out of the loop on all the covenants, ark, bitvm, simplicity, whatever discussion. People ask my opinion about them and I just don't have one 🤷‍♂️

I was initially trying to build a better version of the famous NFC lightning cards - I wanted to add a display so that the user could confirm how much they are paying.

I built that thing and showed it to a bunch of people, and I got pretty negative feedback about it: nowadays lightning is still mostly used for smaller payments, so people want the most convenience, not the most security.

So i ended up repurposing the hardware for a different use-case, on-chain transactions, where security is even more critical.
