We are all newbies in this space - that makes it exciting.
Except for very few coins - most are only usable in their own ecosystem.
SAND is a token (different from a coin) - which means it is built on the Ethereum chain - using its smart contracts Basically SAND could technically then be used on any ETH based payment system for other uses.
I know the sandbox are moving to Polygon (matic) to make the fees cheaper.
If Yat can make it interoperable between different metaverse then fantastic but would currently need to be between the ETH and Matic ecosystem For what its worth there is around $4.5B assets in sandbox currently so the use case for SAND is pretty good.
Im only learning too (and its very new still) so please someone correct me if this is not 100%
