                           https://github.com/valerio-vaccaro/vanitymnem

Create a valid Bitcoin mnemonic with a vanity address in a specific derivation.

Hey this is a PoC! I take no responsibility if you lose your bitcoins using this program! Be careful and use testnet!

Install

You will need python3 and virtualenv plus only one external library (libwally).

Create a virtual environment and load it.

virtualenv -p python3 venv3
. venv3/bin/activate

Install dependencies.

pip install -r requirements.txt

You are ready!

Usage

Just call the script vanitymnem.py with

usage: vanitymnem.py [-h] [-v] [-n NETWORK] [-p PATTERN] [-d DERIVATION]
                     [-c CHILDREN] (--hardened | --no-hardened) [-a ADDRESS]

Create a valid Bitcoin mnemonic with a vanity address in a specific
derivation.

optional arguments:
  -h, --help            show this help message and exit
  -v, --verbose         Be more verbose. Can be used multiple times.
  -n NETWORK, --network NETWORK
                        main, test (default=test)
  -p PATTERN, --pattern PATTERN
                        Regex for pattern
  -d DERIVATION, --derivation DERIVATION
                        Base derivation (default=m/44'/0'/0')
  -c CHILDREN, --children CHILDREN
                        Check in children derivations from 0 to this value
                        (default=100).
  --hardened            Add for have hardened child.
  --no-hardened         Add for have not hardened child.
  -a ADDRESS, --address ADDRESS
                        native_segwit, nested_segwit or legacy
                        (default=native_segwit).

Examples

Generate a mnemonic with a derivation with beef (with upper or lower case chars) in a mainnet legacy address (check on first 1000 derivations hardened).

python vanitymnem.py -p "^.*[bB][eE][eE][fF]" -n main -c 1000  --hardened -a legacy -v
