You mix two different things here. IndoDax stopped trading bcs they have a bug and in the meantime we asked / will ask exchanges to close trading to update their nodes as soon as the code rebase is done.
And the github repo show very little activity. I begin to doubt sumokoin's dev.
True, thanks for your tipp!
Last dev action an 20th July....
