Thanks for posting; I have been looking for such a library to get into the technical details. Do you plan a slack or IRC for collaboration?

I'm posting to divulge a new open-source Bitcoin library written in Java, with support for taproot single key transactions: https://github.com/bitcoin-education/bitcoin-java. My main motivation to build this library was for educational purposes. Also, I was missing a lean bitcoin library written in Java, since I think bitcoinj too feature-heavy. I don't intend to include features that allow communication with nodes nor any online features in it. I think it is ideal for developers that want to build a wallet in Java. Feedback, PRs, and issues are welcome and appreciated. Website of the project, where I plan to post more examples using it: https://www.bitcoineducation.site/ Best regards, Humberto
