Do you wanna any news?
Ok, we have some...

Development is going on, but very slowly - summer, hot, laziness...
We had no plans to continue current Soldo apps development and switched our efforts to new coin base.

But we changed our mind and have to merge new coins codebase and old Soldo/Xoldo into one project.

In any case, Argon2 PoW already implemented and tested and could be activated as soon as we want.
