are there multi altcoin address explorers site where you can check type altcoin
I have never been interested in this, it is possible to track or send-receive coins but there is not a explorer where they are all gathered in one place. These can only be tokens created based on any coin, you can gather them all in one place.
This is close to what you want, just select the coin/token you want before explore. Hopefully you will find it useful :
