I’m checking steps at Setting Up a Validator for f(x)Core Testnet, especially Create Your Validator section and I’m trying to understand the step differences between testnet and mainnet (which are not there yet).
However, for testnet I would expect different addresses to be setup.

Note: Don’t worry about the private key, it’s copy-and-paste from here.
So for testnet, shouldn’t we specify a different coin type (–coin-type) (or purpose) like for Bitcoin? See: bips/bip-0044.mediawiki at master · bitcoin/bips · GitHub (where coin type is 1 for testnet, and 0 for main network).
Otherwise how do we differentiate addresses between testnet and mainnet?
