As far as I know (haven't looked into it in awhile) this is not accurate.
Your wallet can have ecash from multiple mints, yes, but a mint operates by itself ("single server hot wallet").
fedimint expands on the concept, requiring more than just one machine, thus enhancing reliability and security.
Do you have any docs to back that up?
Again, it's possible that it's changed since I looked at it, which is awhile ago.
I tried to find the information now and nothing came up.
I highly doubt based on what I remember about cashu's architecture that your assertion could be correct. Indeed, this is also why fedimint was created in the first place.
