I have a script that works perfectly in creating an inscription taproot address with Javascript https://gist.github.com/ChristianOConnor/fa07462990a74606f486f97031783e50. I committed the private key and inscription text to the code. There’s nothing in the wallet so it shouldn’t be a security problem. The address outputted by the script is tb1pzr0236kw9vnavfl6zjk4xvfsvptfwq2202newug2se5tsg2fmrhsa4hv7z.

Again, I’ve tested the javascript code including spending an inscription output and it works perfectly. I unsuccessfully tried porting the above script to C#. It doesn’t produce the correct address. This is the C# script https://gist.github.com/ChristianOConnor/2399a864f38666a2a3305b9ad7d374d1 preloaded with the same private key and inscription string. It incorrectly produces this address: tb1p90cf5jsmvv2cwu7wq2k60pewtpu5xvlfypxwjeag4aq9yhaccgks68fc8j.

Can anyone fix my C# script so that it produces the correct address aka tb1pzr0236kw9vnavfl6zjk4xvfsvptfwq2202newug2se5tsg2fmrhsa4hv7z.

This would be unpaid, but if you can fix the C# script I’ll open source it and MIT license the code. P.S. Could you please perpetually MIT license your fix for the C# script.
