user2248: Does anyone have good resources on the PAB connecting to the testnet? I know Lars Brünjes explained it in the pioneers program, but, at that time, we still had to rely on the emulator.
I also know we have plutus-apps (with Nami demo) and plutus-starter, which are good resources, but there are not a lot of explanations of what each thing does.
Any videos, blog posts or even well-documented repositories would be of great help.

user4023: You should read Plutus starter PAB testnet notes and Hosted PAB setup for Alonzo testnet gist.
