The CTV examples in Oct/Nov 2023 were me and a friend demo testing pathcoin (see fidelitybonds.py for the scripts).
(at least … I’m 99% sure … I certainly did it around then just before the San Salvador conference but didn’t keep a record, and the scripts match exactly)
Perhaps not the most practically realistic use-case but, interesting experiment 
thanks for setting it up to be usable on signet!
