Minimal dependency coin address from xpub generator for python

coinaddress

Crypto address generator from xpub

• Free software: MIT license

Features

• generate addresses for multiple blockchains from extended public key (xpub)
• minimum dependency (it means security)
• CLI interface

Getting started

Install package using pip (prefer virtualenv):

pip install coinaddress

And you can start use provided CLI. Read help first:

coinaddress --help

To generate 1000 addresses for bitcoin xpub from file (xpub should be a single line in this file):

cat xpub.txt | coinaddress bitcoin 0 -n 1000

To generate another bunch of addresses:

cat xpub.txt | coinaddress bitcoin 1000 -n 1000

xpub can be passed with --xpub option but you should avoid this and prefer read from file for security reasons.

Using from code

You can use public python interface to convert addresses:

from coinaddress import address_from_xpub
address_from_xpub(
    network='bitcoin',
    xpub='<XPUB>',
    path='0/0'
)
