Welcome to the page of Txbit.io exchange with the above link (if it is real one).
However, I don't know this is official link or not, because Solaris team have not announced about it in the OP and in the website.
Any ideas?
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.
