Looks good, although I am missing some testing.

@paulbellamy not sure why, but the mac tests are failing. could you fix those ?

[paulbellamy]

Seems like merging main fixed the mac tests.

Just a note on where this PR is at:
I'm not really sure where to go with testing this at the moment... I can't (currently) seem to get a working standalone quickstart/rpc/cli/contract with a matching xdr version. And trying to refactor the cli/rpc client so it could be mocked & unit tested is extremely painful, due to the rust jsonrpsee traits (but maybe possible?) :/

[2opremio]

@willemneal could you take over the testing?

Closing this in favor of #931
