How will it require a new token listing? All that changes is that sonm will run on its own chain but a lot of projects do it like that.
I don't see a problem either, if they want to migrate SNM to an another chain they just perform a token swap and that's it. There also chains compatible with ERC20 tokens, talking about EOS and ARK in the future
Yeah this is happening with a few projects late;y, should not be anything challenging to swap the tokens as necessary
if sonm migrate to another chain their work on sonm developments and update might disturb
and migration will take time. its not gonna happen in one day
i think sonm on eth network chain is going good their is no need to migration on another chain
when everything ready then sonm should move to their own blockchain
