Does anyone know and want to share any information on how to connect PAB to public testnet (not simulator) or mainnet? Are there any examples/tutorials for it?
You have the best instruction here https://gist.github.com/mikekeke/883d56c38e0237444ac98ae5257e174f
Also after the setup on the above link, you can use this starter project generated from the Plutus starter template just updated to work with PAB on testnet https://github.com/invictusappscom/plutus-starter-pab-testnet Here main differences from https://github.com/input-output-hk/plutus-starter are that dependencies are updated and it is added
plutus-pab.yaml configuration file. Also here instead of simulator it is using the real PAB https://github.com/invictusappscom/plutus-starter-pab-testnet/blob/main/pab/Main.hs
