What the hell is Dogecash Explorer? And why are you sharing a different block explorer?
The explorer you shared seems to focus on a certain type of chains, some of which are long dead or barely have any transactions in them, and it doesn't even list any Dogecash in there. I wonder what your intention is. Are you trying to advertise your coin, perhaps?
At first, I thought it was like a tool to check if we have a Dogecash hidden in our wallet and we can withdraw and sell them just like what we did in Bitcoincash but nah I was wrong. What the OP really have there is literal explorer and it is not even limited to Dogecash or Dogecoin. There is also no ' install ' button there, so how can we install it @OP?
Anyways, just like the other explorers, there is even no need to install them but we can just bookmark them if we want to use them. If all this are for advertising purposes, then he can do it better like he is going to be more specific. That way, he can have more chance to gain a visitor at least.
