While I'm pretty sure this is the official website is
http://darkwallet.is/ , I don't remember seeing the website like this.
It looks like the designed changed to the worst and contains less information's and nothing about the development and donations like If the project is finished.
If you click download you will see a link to the browser plugin which was supposed to be released in the first place + a Firefox add-on (which now no longer exists) .
The weird thing now is that you can download a Ubuntu client ? since I was following the project and didn't see any info about any Ubuntu client , the GitHub project is hosted somewhere else (on another account)
Twitter account is pretty much inactive since 2015 just like the GitHub repository and donations page is no longer working
