# HD Key-Derivation

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**. 

{% hint style="info" %}
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.
{% endhint %}
