I am not sure, but probably they raised funds via fiat investments. In any way, now projects aren't that transparent and somehow they don't want to show smart contracts and so on.
In any case, let's wait official announcement
That's right, we need to wait for the official announcement, there is simply no other way out. I hope it will happen soon.
In fact, it is rather strange that developers do not open smart contracts, and it is not clear why the payment is in cash. Nevertheless, it is a project with great potential.
