Well, this is a guide we could have used a few months ago! Anyway, econoalchemist has written yet another guide on how to make a self-custodial lightning node with Raspiblitz, same as we have.
You can read the full guide on econoalchemist’s blog. https://www.econoalchemist.com/post/build-a-self-custodial-lightning-node-with-raspiblitz
Find Raspiblitz on the Fulmo shop https://shop.fulmo.org/
