Many thanks for the reply, can I just clarify how I can do this.
Firstly I've not used wallet descriptors before so this might be a daft question but this bit here...
sh(wpkh(
I initially read that as do a shell script with a custom wpkh executable but now not sure. Is it shell script or is this something in the wallet descriptor format I should be learning about?
Sorry, I forgot to link through to the descriptor documentation in my original post... You might want to have a read of the docs here:
https://github.com/bitcoin/bitcoin/blob/master/doc/descriptors.mdThey will do a much better job of explaining all the syntax of the various descriptors and how they work. Feel free to ask if you need any further clarification.
