I don't think this is a reasonable expectation especially if we account for new mints coming online in the future
Discussion
It could work if mint operators agreed to team up and open zero fee routing channels between each other. If each mint had at least 2 such channels to other mints, all routing between mints would be free.
Added bonus is that channel rebalancing between mints would be free too.
I’m in for this. Where do we connect to negotiate the channels?
Some mint runners list their contact details which you can find from the auditor
