Project description

Python SteemEngine

Build Status

A small library for querying and interfacing with the SteemEngine network, including sending and issuing tokens.

Official Repo:


This Python SteemEngine library has been developed at Privex Inc. by @someguy123 for both simple querying, as well as transaction signing (sending, issuing) on the SteemEngine network.

It uses the following libraries:

Quick Install / Usage

pip3 install privex-steemengine
from decimal import Decimal
from privex.steemengine import SteemEngineToken
s = SteemEngineToken()

# Get all SteemEngine transactions for @someguy123 
for tx in s.list_transactions('someguy123'):
    print(tx['timestamp'], tx['symbol'], tx['quantity'], tx['memo'])

# Get the amount of ENG that @someguy123 owns, as a Decimal()
print(s.get_token_balance('someguy123', 'ENG'))
# 0.00

# Issue 1.234 SGTK to @someguy123 - automatically detects the issuing account
s.issue_token('SGTK', 'someguy123', Decimal('1.234'))

# Send 10 ENG to @privex from @someguy123 with the memo 'hello memo'
s.send_token('ENG', 'someguy123', 'privex', Decimal('10'), 'hello memo')

For full parameter documentation, IDEs such as PyCharm and even Visual Studio Code should show our PyDoc comments when you try to use the class.

Screenshot of PyCharm SteemEngine Help

For PyCharm, press F1 with your keyboard cursor over the class to see full function documentation, including return types, parameters, and general usage information. You can also press CMD-P with your cursor inside of a method's brackets (including the constructor brackets) to see the parameters you can use.

Alternatively, just view the files inside of privex/steemengine/ - most methods and constructors are adequately commented with PyDoc.


Read the 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 use the various functions and classes
  • General documentation of the modules and classes for contributors

To build the documentation:

git clone
cd python-steemengine/docs
pip3 install -r requirements.txt

# It's recommended to run make clean to ensure old HTML files are removed
# `make html` generates the .html and static files in docs/build for production
make clean && make html

# After the files are built, you can live develop the docs using `make live`
# then browse to
# If you have issues with content not showing up correctly, try make clean && make html
# then run make live again.
make live

Signing Transactions

For signing transactions, you will need a Beem wallet, with the password specified as the environmental variable UNLOCK. In most Python web apps, you can place this in your application's .env file for automatic loading.

Install Beem globally to use the beempy command, create a wallet, then import the active keys of the Steem accounts you'll be using to transact on SteemEngine.

# Install beem globally (not in a virtualenv) for the `beempy` command to manage wallets
pip3 install -U beem
# Create a wallet, keep the password safe, you'll need to pass it to your script
beempy createwallet
# Import any active keys for accounts that you'll be transacting with
beempy addkey

Example Python script:

#!/usr/bin/env python3
from decimal import Decimal
from beem import Steem
from beem.instance import set_shared_steem_instance

# Create an instance of Steem, and set it as the shared instance, so that it can be used by the library
steem_ins = Steem()
steem_ins.set_password_storage('environment')   # Tell Beem to use the `UNLOCK` env variable to unlock the wallet

from privex.steemengine import SteemEngineToken
s = SteemEngineToken()
# Replace the below parameters as needed. 
# Send 10 ENG to @privex from @someguy123 with the memo 'hello memo'
s.send_token('ENG', 'someguy123', 'privex', Decimal('10'), 'hello memo')

Save the above as

# Make your script executable
chmod +x
# Run the script, passing in your wallet password with the UNLOCK env variable.
UNLOCK="YourWalletPassword" ./

Beem will now be able to automatically unlock your wallet to sign a Steem transaction, such as when sending or issuing tokens.

We recommend using something like python-dotenv in your Python projects so that you can store the password in a .env file (make sure to use secure file permissions for .env)


We recommend that you use at least Python 3.4+ due to the usage of parameter and return type hinting.

Install from PyPi using pip

You can install this package via pip:

pip3 install privex-steemengine

(Alternative) Manual install from Git

If you don't want to PyPi (e.g. for development versions not on PyPi yet), you can install the project directly from our Git repo.

Unless you have a specific reason to manually install it, you should install it using pip3 normally as shown above.

Option 1 - Use pip to install straight from Github

pip3 install git+

Option 2 - Clone and install manually

# Clone the repository from Github
git clone
cd python-steemengine

# Use pip to install the source code
pip3 install .

# If you don't have pip, or have issues with installing using it, then you can use setuptools instead.
python3 install


By default, this package will log anything >=WARNING to the console. You can override this by adjusting the privex.steemengine logger instance.

We recommend checking out our Python package Python Loghelper which makes it easy to manage your logging configuration, and copy it to other logging instances such as this one.

# Without LogHelper
import logging
l = logging.getLogger('privex.steemengine')

# With LogHelper (pip3 install privex-loghelper)
from privex.loghelper import LogHelper
# Set up logging for **your entire app**. In this case, log only messages >=error
lh = LogHelper('myapp', handler_level=logging.ERROR)
lh.add_file_handler('test.log')        # Log messages to the file `test.log` in the current directory
lh.copy_logger('privex.steemengine')   # Easily copy your logging settings to any other module loggers
log = lh.get_logger()                  # Grab your app's logging instance, or use logging.getLogger('myapp')
log.error('Hello World')

Unit Tests

Unit tests are available in We also have the project set up with Travis CI to alert us when new releases cause the tests to break.

To run the tests manually, either simply run directly (or with python3), or use pytest:

git clone
pip3 install .
# Verbose mode (shows the name of the test, and the comment under it)
./ -v

# You can also use pytest - which is used by our Travis CI setup.
pip3 install pytest
# Verbose mode


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 privex-steemengine, beem and requests tested on - use pip3 freeze
      • If not installed via a PyPi release, git revision number that the issue was tested on - git log -n1
    • Your python3 version - python3 -V
    • Your operating system and OS version (e.g. Ubuntu 18.04, Debian 7)
  • For feature requests / changes
    • Please avoid suggestions that require new dependencies. This tool is designed to be lightweight, not filled with external dependencies.
    • 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.
