The derivation paths used for HD Key-Derivation are important in case someone needs to recover from a seed phrase only and if particular private keys should be imported to other wallets, e.g. Metamask.
Minerva uses three derivation paths:
Identities (DIDs) -> m/73'/0'/0'/index
Main Networks -> m/44'/60'/0'/0/index
Test Networks -> m/44'/1'/0'/0/index
This clear distinction allows Minerva to avoid any mixing of indexes for identities (DIDs), main networks (e.g. Ethereum, ARTIS ∑1 or xDai Chain) and test networks (e.g. Kovan, Rinkeby or Görli).
If the Minerva seed phrase (12-words) is imported to Metamask, it will generate the same keys and consequently the same addresses for main networks.
Metamask won't be able to access your tokens and coins you handled in Minerva on the test networks like Kovan, Rinkeby, Görli, etc. unless you use another tool to get a private key for the account at a specific path and import that into Metamask.
