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) ->
Main Networks ->
Test Networks ->
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.
