It seems to work really well and I am very excited that there is another statechain implementation in the wild

One thing I like about statechains is that they offer similar privacy protections as cashu mints (e.g. they both use a blinded server, though I'm not certain this implementation uses one -- will have to ask) but they improve upon them in some respects (e.g. they carry less risk of shotgun kyc)

The usual caveats apply, however: in the statechain model, the operator is trusted to prevent doublespends, which means they can steal from you by authorizing a doublespend. So don't use them unless you trust the operator not to do that.
