PAB setup
This document describes how to prepare hosted PAB deployment from scratch that can operate on Alonzo purple testnet.
The following required to be run on host machine to use PAB with contracts in hosted scenario on testnet (for 2020-11-05 PAB Release):
- Cardano node connected to Alonzo testnet
- cardano wallet connected to node
- chain-index connected to node
- PAB executable connected to node, cardano-wallet and chain-index
Note: we are using somewhat more involved setup with a bit custom docker compose, and wallet and chain-index being built from sources, but there is ready to go node+wallet docker solution available
