So far I have not seen any DAG project doing something useful in crypto space.
I am not sure SMartX will be any better, but maybe I am wrong.
Sooner or later, such a platform will appear. Or perhaps already appeared.
I also studied this topic a lot earlier and saw that there were teams that tried to make a similar product, but nothing worked out for them.
I communicated with the SMARTX team and I am sure of them, they are real professionals. I think in the future they may become monopolists in this market.
