ecashaddress

ecashaddress is python library which is able to convert legacy bitcoin addresses to the cashaddress format, and convert between various cashaddr prefixes.

It also provides a command line tool for working with address formats.

Installation

To install this library and its dependencies use:

pip install ecashaddress

Usage examples

As a library

The first thing you need to do is import the library via:

from ecashaddress import convert
from ecashaddress.convert import Address

Converting address

You can convert your address via:

address = Address.from_string("155fzsEBHy9Ri2bMQ8uuuR3tv1YzcDywd4").to_cash_address()

or

address = Address.from_string("ecash:qqkv9wr69ry2p9l53lxp635va4h86wv435ugq9umvq").to_legacy_address()

You can convert between different CashAddr prefixes:

address = Address.from_string("ecash:qqkv9wr69ry2p9l53lxp635va4h86wv435ugq9umvq").to_cash_address(prefix="foobar")

Validating address

You can also validate address via:

convert.is_valid('155fzsEBHy9Ri2bMQ8uuuR3tv1YzcDywd4')

or

convert.is_valid('ecash:qqkv9wr69ry2p9l53lxp635va4h86wv435ugq9umvq')

Guessing a prefix

You can guess the prefix for a cash address. This only works for a short list of commonly used prefixes, such as "ecash", "bitcoincash", "simpleledger" or "etoken".

convert.guess_prefix('qqkv9wr69ry2p9l53lxp635va4h86wv435ugq9umvq')

As a command line tool

When the library is installed with pip install ecashaddress, a command line tool is also installed. It should normally be installed in a location that is on your PATH, so you can run it from anywhere in a console:

ecashaddress --help

If this is not the case, an alternative is to run the library the following way:

python -m ecashaddress --help

This tool lets you convert one or more addresses to eCash addresses. It accepts as input addresses with legacy BTC format, or any valid CashAddr. By default, it outputs CashAddr with the ecash: prefix.

ecashaddress convert bitcoincash:qq3dmep4sj4u5nt8v2qaa3ea7kh7km8j05dhde02hg

To output a CashAddr with a different prefix, use the --prefix option:

ecashaddress convert bchtest:qq3dmep4sj4u5nt8v2qaa3ea7kh7km8j05f9f7das5 --prefix ectest

The tool also lets you guess the prefix from an address without prefix, if the prefix is in a short list of commonly used prefixes:

Development

1. Fork the repository on github.
2. Clone your fork of the repository.

3. Add the source repository as a remote.

   git remote add upstream git@github.com:PiRK/ecashaddress.git
   git fetch upstream

4. Make sure your master branch is up-to-date with the upstream master.

   git checkout master
   git pull upstream master

5. Create a local development branch, and add commits to it. Run the tests after each change, before git commit.

   git checkout -b my_dev_branch
   # do your stuff
   python -m ecashaddress.tests.test
   git commit

6. Push you branch to your fork of the repository.

   git push --set-upstream origin my_dev_branch

7. Create a pull request to the upstream repository.
