What does "chain abstraction" mean to you?

Is it being able to move between chains with very low friction?

Is it completely hiding the specifics of which chain you're using?

Or is it leaning into the distinction, but letting you use one chain to trigger actions on another one?

I have my take; curious to hear yours

(First time hearing the term so might be way off)

Feels more about whether or not chain is backing the system being abstracted away.

On the other hand — "multi-chain" or "chain-agnostic" feels more aligned to "move between chains".
