CryptoToken Converter by Privex

Developed by Privex Banner

CryptoToken Converter is a Python web application designed to allow anyone to run their own conversion service between two or more cryptocurrencies/tokens.

It has been developed to be highly modular and customizable, with a REST API for easy integration into your own user interfaces, services, and automated scripts (bots).

This project is currently in beta stage, some things may not be finished, or lack clear documentation

Full documentation for this project is available above (click the Read The Docs image), including:

  • How to install the application and it's dependencies
  • How to configure it properly
  • How to add your own Coin Handler for new cryptocurrency/token support
  • General documentation of the modules and classes for contributors

The documentation is written in reStructured Text, with compilation to HTML and automatically generated class/module docs using Sphinx.

This project is licensed under the GNU AGPL v3

For full details, please see LICENSE.txt and AGPL-3.0.txt.

Here's the important parts:

  • If you use this software (or substantial parts of it) to run a public service (including any separate user interfaces which use it's API), you must display a link to this software's source code wherever it is used.

    Example: This website uses the open source CryptoToken Converter created by Privex Inc.

  • If you modify this software (or substantial portions of it) and make it available to the public in some form (whether it's just the source code, running it as a public service, or part of one)

    • The modified software (or portion) must remain under the GNU AGPL v3, i.e. same rules apply, public services must display a link back to the modified source code.
    • You must attribute us as the original authors, with a link back to the original source code
    • You must keep our copyright notice intact in the LICENSE.txt file
  • Some people interpret the GNU AGPL v3 "linking" rules to mean that you must release any application that interacts with our project under the GNU AGPL v3.

    To clarify our stance on those rules:

    • If you have a completely separate application which simply sends API requests to a copy of CryptoToken Converter that you run, you do not have to release your application under the GNU AGPL v3.
    • However, you ARE required to place a notice on your application, informing your users that your application uses Cryptotoken Converter, with a clear link to the source code (see our example at the top)
    • If your application's source code is inside of CryptoToken Converter, i.e. you've added your own Python views, templates etc. to a copy of this project, then your application is considered a modification of this software, and thus you DO have to release your source code under the GNU AGPL v3.
  • There is no warranty. We're not responsible if you, or others incur any damages from using this software.

  • If you can't / don't want to comply with these license requirements, or are unsure about how it may affect your particular usage of the software, please contact us. We may offer alternative licensing for parts of, or all of this software at our discretion.

External Packages/Libraries used

The main external packages/libraries that are used in this project are:

  • (3-Clause BSD) Django - The web framework this project is built upon

  • (3-Clause BSD) Django REST Framework - A third party package for Django, used for building the REST APIs of this project

  • (Apache 2.0) Python Requests - Used within our privex-jsonrpc library

  • (MIT) Beem - For handling transaction signing and general data queries on the Steem Network - used within our python-steemengine library

  • (BSD) Sphinx - Used for generating the HTML documentation for this project.

  • (MIT) sphinx-autobuild - For automatic re-building of documentation when files are changed, including automatic reloading when using it's built-in web server.

  • Python packages that we've developed and maintain ourselves, used within this project:

    • (MIT) python-steemengine - For sending/issuing tokens on the SteemEngine Network, as well as loading transaction history.

    • (MIT) python-jsonrpc - Used for interacting with cryptocurrency daemons which have a bitcoind-compatible JSONRPC API, as well as a component of python-steemengine

    • (MIT) python-loghelper - Used for managing the logging configuration of this project.

Building the Documentation

If you'd like to contribute to the documentation, it's included in this repo.

Before you can build the documentation, you'll need to at the very least install the Python dependencies for the main project with pip3 install -r requirements.txt

To build the documentation, first enter the docs folder and install the documentation python packages (they're not included in the main project requirements.txt as they're only needed for the docs)

cd docs/
pip3 install -r requirements.txt

For development purposes, we've included sphinx-autobuild, which automatically re-builds the documentation when you change it, and also offers auto-refresh if you access the docs via the webserver at

To build the documentation with automatic re-building on edit, plus auto-reload:

# Run sphinx autobuild
make live

To build the documentation normally, run the following:

# Clean out the previous html files, and then re-build them fresh
make clean; make html

If you encounter any strangeness, such as items missing from the left navigation bar, or content not showing up, you should make sure to run make clean to ensure the HTML files are re-built from fresh.


We're very happy to accept pull requests, and work on any issues reported to us.

Here's some important information:

Reporting Issues:

  • For bug reports, you should include the following information:
    • Version of the project you're using - git log -n1
    • The Python package versions you have installed - pip3 freeze
    • Your python3 version - python3 -V
    • Your operating system and OS version (e.g. Ubuntu 18.04, Debian 7)
  • For feature requests / changes
    • Clearly explain the feature/change that you would like to be added
    • Explain why the feature/change would be useful to us, or other users of the tool
    • Be aware that features/changes that are complicated to add, or we simply find un-necessary for our use of the tool may not be added (but we may accept PRs)

Pull Requests:

  • We'll happily accept PRs that only add code comments or README changes
  • Use 4 spaces, not tabs when contributing to the code
  • You can use features from Python 3.4+ (we run Python 3.7+ for our projects)
    • Features that require a Python version that has not yet been released for the latest stable release of Ubuntu Server LTS (at this time, Ubuntu 18.04 Bionic) will not be accepted.
  • Clearly explain the purpose of your pull request in the title and description
    • What changes have you made?
    • Why have you made these changes?
  • Please make sure that code contributions are appropriately commented - we won't accept changes that involve uncommented, highly terse one-liners.

Legal Disclaimer for Contributions

Nobody wants to read a long document filled with legal text, so we've summed up the important parts here.

If you contribute content that you've created/own to projects that are created/owned by Privex, such as code or documentation, then you might automatically grant us unrestricted usage of your content, regardless of the open source license that applies to our project.

If you don't want to grant us unlimited usage of your content, you should make sure to place your content in a separate file, making sure that the license of your content is clearly displayed at the start of the file (e.g. code comments), or inside of it's containing folder (e.g. a file named LICENSE).

You should let us know in your pull request or issue that you've included files which are licensed separately, so that we can make sure there's no license conflicts that might stop us being able to accept your contribution.

If you'd rather read the whole legal text, it should be included as privex_contribution_agreement.txt.

Thanks for reading!

If this project has helped you, consider grabbing a VPS or Dedicated Server from Privex - prices start at as little as US$8/mo (we take cryptocurrency!)

You can’t perform that action at this time.
