Cardano Addresses

⁠Overview

This module provides mnemonic (backup phrase) creation, and conversion of a mnemonic to seed for wallet restoration, and address derivation functionalities.

⁠Documentation

API documentation is available here⁠.

⁠Command-Line

cardano-address comes with a command-line interface for Linux. See the release artifacts⁠ or continuous integration artifacts⁠ to get a pre-compiled binary, or build a Docker image⁠. The command-line is self explanatory by using --help on various commands and sub-commands.

:bulb: Most commands read argument from the standard input. This prevent sensitive information from appearing into your shell history and, makes it easy to pipe commands!

Here's are some key examples:

How to generate a recovery phrase 
$ cardano-address recovery-phrase generate --size 15
east student silly already breeze enact seat trade few way online skin grass humble electric
How to generate a root private key 
$ cardano-address recovery-phrase generate --size 15 > recovery-phrase.prv
$ cat recovery-phrase.prv | cardano-address key from-recovery-phrase Shelley

Notice the xprv prefix to identify an extended prvivate key. Should you prefer an hexadecimal output, you can choose a different output encoding via a special flag:

$ cat recovery-phrase.prv | cardano-address key from-recovery-phrase Shelley --base16

How to generate a public stake key

:information_source: 1852H/1815H/0H/2/0 is the derivation path that is typically used by Cardano wallet to identify a stake key within HD wallet. If you seek compatibility with Daedalus or Yoroi, use this as well!

How to generate a delegation address

Follow the steps from 'How to generate a payment address'. Then, simply extend an existing payment address with a stake key!
