That is official link but just dev not updated yet the link in the OP. They are just busy now testing and doing background work to make sure all will go well after exchange launch, i think.
Honestly, I am waiting for the Txbit.io exchange for months.
I also known that you are one of the strongest supporters of Solaris project because you joined the first wave of Solaris signature campaign last year and kept supporting Solaris continuously till now.
Another solid supporter of Solaris project, who I known via the ANN topic, is @vella.
Now, it's time to enjoy the coming promising ride with effects of Txbit.io exchange, which is highly expected from all members of Solaris community.
It's good to see long time loyal supporters are being recognized. A strong community is one of the factors of a successful crypto project. Txbit.io will be a great addition to the already excellent exchanges that Solaris is listed on.
