Title: public master keys to addresses Post by: thaten on January 17, 2023, 04:08:04 PM Hello,
I am searching for a self Hosted (!!) solution to generate addresses from a public zpub key. It would be great, if it has an intigrated rest api inside. Maybe something for nodejs would be very nice. This would be a nice solution for cold storage wallets. I am currently using https://github.com/romanz/electrs for various stuff, but unfortunately I dont find any api details anymore.

The documentation for the Electrum Server Protocol is the same as for ElectrumX, i.e. this one: https://electrumx-spesmilo.readthedocs.io/en/latest/protocol.html Electrs most probably also follows that.

This one for example, seems to fit almost exactly your description; since it's in JavaScript it should be easy to embed it in a NodeJS application with API that you add yourself. https://github.com/swan-bitcoin/xpub-tool Title: Re: public master keys to addresses Post by: thaten on January 18, 2023, 06:53:27 AM I am currently using https://github.com/romanz/electrs for various stuff, but unfortunately I dont find any api details anymore.

Thanks, I will look into that and update, once it is working.https://learnmeabitcoin.com/technical/images/extended-keys/child-extended-public-key-normal.png That being said, existing solutions can be found easily on GitHub.
