This chain can be used to create token ala Ethereum, but they are not SMT. They are smart contract tokens not tied in, hence will not have the same properties. Can that be added? I am not sure. But not every token requires interacting similar to STEEM.

Once Steemti does create the SMTs, that is at the blockchain level so this will tie into it. Anything does at the base layer can be read by the apps.

This is a secondary layer which, even if developed by Steemit, would have to be. For example, the naming or unnamming of moderators is not something you want at the base level. That belongs on a secondary layer.

I hope I answered your question.
