Yes, there's nothing stopping it technologically from functioning in a similar way. Someone has to build it of course, but it shouldn't be much harder than building something for an ecash mint. It's kind of the same principle.

A Fedimint can act as a lightning gateway to the outside world letting you receive/send ecash.

Similarly a mercurylayer statechain provider can do the same. Act as a LN gateway and give you statechain "UTXOs".

haha... saw that page when release was announced here. I need the ELI5 version though 🙃 I get the general idea that ownership of private keys is passed around.

so does/can/will mercury function in similar way to these ecash mints?
