Set up a Substrate RPC node

This is a quick guide to set up an RPC node so that you can interact with your blockchain via a UI such as https://polkadot.js.org/apps.

Here is the command to launch a non-validating, non-archive, full (RPC) node:

Once your node is running, you can interact with it by going to https://polkadot.js.org/apps and clicking the drop down in the top-left corner > development > Local Node and the clicking “Switch” at the top of the screen.

If your ` — ws-port` is not 9944 then instead click Custom and enter the custom port.
