BIP-85 in AirGap Vault

  • Go to the Settings page and choose the mnemonics/account from which you wish to derive the child seed.
  • Click “Generate BIP85 Child Mnemonic”
  • On the BIP-85 Generation page, you can set a few settings
  • Mnemonic Length: The length of the child mnemonic is defined by this parameter.
  • Index: Changing the index will result in a different child mnemonic being generated. Therefore if you want a new mnemonic for a new purpose, make sure to set the index to a value that has not been used in the previous mnemonic generation process.
  • Advanced Mode — BIP-39 Passphrase: This allows you to set an extra passphrase that will be used to derive entropy.
  • On the following page, you can see the mnemonic that was derived from the master mnemonics. You can now write it down on a piece of paper or copy and paste it into another wallet without any problems.
  • If you click on the validate button, the next screen will confirm that you have accurately written down the child mnemonic.
