I couldn't make it work on signet.

Thanks for testing @iorch !!

And thanks for the excellent PR @ca-ruz !

ACK 6038170

[chrisguida]

@iorch no, sauron does not support mutinynet ot signet at the moment. I don't know of an esplora API for signet, but mutinynet.com has a great esplora API for mutinynet. If you wanted to add mutinynet support to sauron that would be amazing :D
