I'm facing my first sawtooth app and I'm not sure how you are supposed to handle the user's keys to sign transactions locally. The client is going to be a web app.
I was wondering if there is something like metamask for sawtooth, or even if metamask would be officially compatible with sawtooth. I've checked this question and it seems to work, but with low level changes that make me wonder if that will work for long.
What is the recommended way to do this?

I’m building the Open-sea Dapp to practice myself. I’m just wonder if I can use Moralis and Thirdweb with each other. Is it possible? I’m connecting MetaMask with Moralis and I would like to have another page that contains the Collections that I have in Thirdweb.
GM there!
That should be possible, but seems like Moralis' functionality is overlapping a lot w/ Thirdweb, recommend that you choose either one
However, if you use our new Moralis 2.0 now we're backend focus and only provide you with APIs to index the blockchain, so that way you can just have Thirdweb used for interaction with the smart contracts
Let me know if you are not clear with this
Cheers~
so far so many Dapp developers have made so many Dapps which are integrated with MetaMask or other similar extensions like Parity and Web3.js.
Is there any idea or suggestion about developing one without all those extensions mentioned above ?
Thank you.
There are mostly two reasons these extensions exist:
The user shouldn't need to trust the website to provide their. blockchain data source, and more importantly, users should never have to trust a web app with their account's private key.
Of course you can make sites without those guarantees, but to do that kind of misses the point of decentralizing trust.
I've recently came across a project in alpha: https://fortmatic.com
It gets rid of the need to use DApps without extensions. Docs seems pretty good, was able to get things working pretty fast. It triggers a modal in an iframe for user auth (similar to Stripe or Plaid) - imo this feels like a better ux as the end users never have to leave the main dapp experience
I'm trying to find a way to launch a desktop application from a browser for os x. This application will be for customers only and should only be used for the hardware we provide.
I'd like to start off by saying I think this is a stupid idea. I'm being forced to use this approach by our CEO. I understand security policies could be an issue, as well as glaring vulnerabilities.
Since they can only run this on a single device I don't know that jws would be the right solution. I haven't used it but based on what I've read it doubles as a distribution method (which we don't want). If it were to be jws then it would have to some how have to recognize the device we provided them to ensure it is being placed on the appropriate hardware, possibly based on the serial # (which I don't believe you can get from the browser).
Additionally, the browser would call methods and pass arguments to the application.
Is this even possible? If so, what tool would you recommend? Again, I'm only the messenger for this terrible idea.
You probably have Chrome or Safari configured to handle http://<uri> URIs, but many other types exist. Have you ever seen custom URI schemes used like itunes://<uri>, steam://<uri>, or skype://<uri> ?
Just like for http, when your OS tries to fetch the resource, it will attempt to handle the request in the application that registered a handler for that scheme.
If that's the kind of thing you're looking for, this question has already been answered.
My suspicion is that you were unaware of the term. If that answer works for you, we can mark this question as a duplicate.
In complement to #naomik's answer (which I believe is the right one), there are projects like AppJS, Fluid or Electron which are pretty much willing to bring web based apps to the desktop.
For the matter of communicating the App and your browser (should I say your server?), you could use an approach of message queues and websockets to get there, surely, it is a huge effort of orchestration and workarounds but in the end it is possible to get you there.
(Posted on behalf of the OP).
This does not appear to be possible. If you are considering this please don't, there are better solutions. I have finally convinced my CEO to use Angular2 inside electron for example.
I'm attempting to make a mail client that is HTML5/JS only where users would have to define their mail server and credentials.
I've surfed google leading to dead ends and figured that this is the next best place (or superuser.com).
I was thinking of using HTML5 WebSocket if I could to make the connection to the server but I don't know enough of smtp, imap, or pop3's architecture to understand how javascript could pass the args and perform what I want it to do.
PHP cannot be involved in this project otherwise I wouldn't be asking the question.
Any help in locating this would be fantastic.
Nothing is impossible. Except this.
In standard HTML or JavaScript, you can't make raw-socket connections, which is what you'd need to speak any of the protocols you've listed. The WebSocket API doesn't help you, because the server must also speak WebSockets, and mail servers don't. This is actually all a good thing, though. Imagine if you visited a random website and it telnetted to your home router, setting it on fire and burning down your house. That's what websites would be able to do if they could initiate plain TCP socket connections.
You have a few options I can think of, neither of which involves building a webpage. (And to be clear, you didn't say your project had to be a webpage; you merely said HTML/JS, so these are indeed legitimate options.)
First is something like node-webkit. As the readme says, "You can write native apps in HTML and Javascript with node-webkit." You'll still have to distribute it as a native app, because that's what it is.
Second is a Chrome app, specifically using the chrome.socket API. But have fun writing a TLS layer over those sockets, which you'll find is a requirement for almost any mail server these days. If you succeed in doing that, you'll be able to distribute your mail client in the Chrome Web Store, where I assure you an email client will be quite popular.
Third, write a webserver that operates locally, so your users will visit something like http://localhost:9999/mail in their browser. This will be a real pain to distribute, but you can use almost any technology you want.
I'm sure there's a fourth valid option, and someone else can chime in on that one.
Best of luck.
I am trying to figure out a way to do an internet connectivity check for an AIR for iOS app. Previously, I was using (against my better judgement) a URLMonitor that checked Google once every 30 seconds. I did not like putting that load onto Google and neither did they; this morning, our network got flagged as a possible DDoS attacker simply from testing the app. So I had to disable this type of check and move on.
I have thought about using the NetworkInfo ANE from Adobe, but that presents its own issues in determining internet connectivity. The only way I can think of doing it is to check for interfaces "en0" and "pdpxx" (which correspond to WiFi and Cellular interfaces, respectively) and check their IPs to ensure they are not in the 192.168.x.x, 10.10.x.x, or 127.0.x.x ranges. However, I am not entirely sure those are the only static router/localhost IPs out there and there is always the possibility that the network interface names will change in the future, which would render this monitor useless. There is also the issue of IPv6 possibly throwing a wrench into this method as well.
Is there another way to check if the user is connected to the internet? I've searched multiple times and it seems that these are the only two ways to check. If that is the case, what is the best way to check?
I'm surprised that you got flagged as a DDoS attacker, are you sure that's what happened?
In any case, if your not happy with putting the load onto someone else's server, then make your own server, just a basic setup that you use with the URLMonitor. You don't have to use google's url with the URLMonitor, you can pass it another URLRequest, which could point to your own server.
monitor = new URLMonitor(new URLRequest("http://www.you-own-server.com"));
This might also be useful if you decide that you want to pass more data between the app and the server. It's your server, so can do what you want with it.
I don't think there's any other way to check if the user is connected to the internet. To be honest, I don't see why there would be. Checking for the users interfaces/wan0 etc... probably would be possible, but you'd need another program, maybe a simple python or c++ program, that Air could use to check these things, but that sounds like the long way round.
