subaddress-derive-xmr is a command-line tool that generates a monero wallet and derives addresses

About

This tool can be used to generate a monero wallet and/or derive addresses offline from keys or from a mnemonic without installing full monero software.

Derivation reports show major index (account ID), address index, and address.

Input must be provided with these flags:

--mnemonic : a mnemonic phrase to use an existing wallet
--view-priv and --spend-pub : a private view key and a public spend key
--gen-wallet : generates a new wallet seed and keys.

Reports are available in json, plaintext, and html. Columns can be changed or re-ordered via command-line.

This tool was adapted from: hd-wallet-derive -- a tool for deriving Bitcoin HD-Wallet addresses.

Let see some examples

Generate new wallet keys and master address

$ ./subaddress-derive-xmr --gen-wallet  -g

}

Generate new wallet using alternative wordset

Here we specify --wordset=japanese to generate a mnemonic in Japanese.

$ ./subaddress-derive-xmr --gen-wallet --wordset=japanese -g
{
    "seed": "a6d5b4007d6b05d3a46b8bae199c8eef702c05f4fa219dbc80c84913da1c6a7e",

}

Derive addresses

For deriving addresses we use the private view key and the public spend key. In the examples below, we use the keys that were generated above.

If you want to use keys from your wallet, then in the official Monero GUI, they are available in the Settings->Seed & Keys area. In the CLI, open your wallet and use the commands spendkey and viewkey to find the keys.

./subaddress-derive-xmr --view-priv=25d014a444fb7a1e6836c680d3ec1b6eed628a29c3c85e0379fb89f53c4c610a --spend-pub=dce90ff7304d8b648bfbac69624b4c6562340c5c748a8a6d2c84bad3b76fe974 --numderive=3 -g

+-------------+-------------+-------------------------------------------------------------------------------------------------+
| major_index | minor_index | address                                                                                         |
+-------------+-------------+-------------------------------------------------------------------------------------------------+

+-------------+-------------+-------------------------------------------------------------------------------------------------+

Note that the first address (0,0) is the same address that was generated with --gen-wallet. This is the master address for the Monero wallet and is generated slightly differently from the other subaddresses.

Same keys, different account

For this, we use the --majorindex flag.

./subaddress-derive-xmr --majorindex=1 --view-priv=25d014a444fb7a1e6836c680d3ec1b6eed628a29c3c85e0379fb89f53c4c610a --spend-pub=dce90ff7304d8b648bfbac69624b4c6562340c5c748a8a6d2c84bad3b76fe974 --numderive=3 -g

+-------------+-------------+-------------------------------------------------------------------------------------------------+
| major_index | minor_index | address                                                                                         |

We can easily change up the columns in whatever order we want.

Just use the --cols parameter.

./subaddress-derive-xmr --cols=address,minor_index --majorindex=1 --view-priv=25d014a444fb7a1e6836c680d3ec1b6eed628a29c3c85e0379fb89f53c4c610a --spend-pub=dce90ff7304d8b648bfbac69624b4c6562340c5c748a8a6d2c84bad3b76fe974 --numderive=3 -g

Derive addresses from a mnemonic

The --mnemonic flag makes it happen.

$ ./subaddress-derive-xmr --mnemonic="school bunch godfather school umbrella criminal mowing payment himself tacit tawny dagger phrases blender depth sayings antics bagpipe gels ability ablaze mugged balding apology sayings" -g --numderive=3

+-------------+-------------+-------------------------------------------------------------------------------------------------+

Get seed and wallet keys from a mnemonic

Just use --wallet-keys in addition to --mnemonic. Note that --wallet-keys defaults to jsonpretty output, but that can be changed with the -format flag.

$ ./subaddress-derive-xmr --wallet-keys --mnemonic="school bunch godfather school umbrella criminal mowing payment himself tacit tawny dagger phrases blender depth sayings antics bagpipe gels ability ablaze mugged balding apology sayings" -g
{
    "seed": "e5f8bd36b5d9174725aca5bc88a8ac567a0d1614a840d109af84430001fd56f7",

}

Use a mnemonic with alternative wordset.

Note that "wordset: japanese" is present in the results. The wordset is automatically detected from the words in the mnemonic phrase.

$ ./subaddress-derive-xmr --wallet-keys --mnemonic="すくう あらわ す あんい だいじょうぶ ちしりょう ずっと おもちゃ てはい さんこう そんみん てんかい ちひょう ちたん かかえる おおどおり けわしい きかい はめつ すれちがう はっかく いきおい けねん しんか あらためる ちしりょう" -g

}

Derive addresses from a seed

We use the --seed flag

$ ./subaddress-derive-xmr --seed="66dcbb7490ee34dad1b04fa316b90ba1795ce70586298e2cc09455de1ae95273" -g --numderive=3

Get mnemonic and wallet keys from a seed

Again we add the --wallet-keys flag.

$ ./subaddress-derive-xmr --wallet-keys --seed="66dcbb7490ee34dad1b04fa316b90ba1795ce70586298e2cc09455de1ae95273" -g --numderive=3

How address derivation works

For background, please read Monero's documentation.

Mnemonic wordsets

The wordset list can be obtained with the --help-wordsets flag.

$ ./subaddress-derive-xmr --help-wordsets
+--------------------+-----------------+----------------------+

| spanish            | Español         | Spanish              |
+--------------------+-----------------+----------------------+

A particular wordset can be specified using the --wordset flag with a value from the wordset column. This flag is recognized when generating a wallet or displaying wallet info from a seed.

When a list of words is provided with the --mnemonic flag, the wordset is automatically recognized and --wordset flag is ignored.

note: These wordsets were obtained directly from the official monero source code here. (See *.h files)

The default wordset is english. english_old is a wordset from electrum.

Privacy and Security implications

This tool runs locally and does not make any requests to a server. This eliminates many forms of leaks and privacy issues.

That said, any time when you are working with private keys you should take serious security precautions.

When you run this tool in a terminal, the executed command(s) will usually be saved to a history file -- including your keys used as command arguments. You should be very careful to either expunge the command(s), or move the funds to another wallet, or be certain untrusted parties cannot access your machine.

Finally, this tool depends on libraries written by other authors and they have not been carefully audited for security. So use at your own risk.

Use at your own risk.

The author makes no claims or guarantees of correctness.

By using this software you agree to take full responsibility for any losses incurred before, during, or after the usage, whatsoever the cause, and not to hold the software author liable in any manner.

Output formats

The report may be printed in the following formats:

plain - an ascii formatted table, as above. intended for humans.
csv - CSV format. For spreadsheet programs.
json - raw json format. for programs to read easily.
jsonpretty - pretty json format. for programs or humans.
list - single column list. for easy cut/paste. uses first col.
