Welcome to EOSFactory v3.4.0

EOSFactory is a Python-based EOS smart-contract development & testing framework, created by Tokenika.

With a single command-line interface you can create a private testnet and then compile, test and deploy EOS smart-contracts.

All of this using simple yet powerful Python3 syntax.

Why it’s needed?

Code development and testing involve tasks that need to be executed hundreds of times, and each time in exactly the same way and exactly the same context. Therefore those tasks need to be fully automated, as otherwise a lot of time is being wasted and, what’s even worse, a lot of additional uncertainty is introduced. Manually performed actions are prone to errors.

And this is what EOSFactory actually brings to the table: an easy & intuitive way to automate the process of dealing with smart-contracts. Write down, in the form of a Python script, what needs to be done multiple times in exactly the same way and exactly the same context, and then just run the script. EOSFactory will take care of everything else: it will compile your smart-contract, create a new local testnet, deploy the contract, invoke its methods and verify the response, then tear down the testnet, and finally report the results. And all of this done in a couple of seconds.

Main features

1. Object-oriented

When you use tools like cleos all you have at your disposal is issuing separate, one-off commands, as cleos is not able to keep your state. Thus each time you interact with a contract, you need to tell cleos which contract and which account you mean. Contrary to that, in EOSFactory everything is an object. You create a contract (or an account), keep reference to it and then invoke its various methods.

2. Simple syntax

The front-end of EOSFactory is simply a Python3 Command Line Interface. This way you can interact with EOS smart-contract, and prove it works as expected, instead having to deal with the raw primitives of the EOSIO cleos. In most cases Python syntax is immediately clear for everyone.

3. Support for both local and remote testnet

Running tests on a public testnet is much more complex than using a local one where you have full control. The whole infrastructure of EOSFactory is designed in such a way that the same test is able to work in both environments, and switching between them is just a matter of changing one parameter.

4. Aliases for account names

EOSIO accounts are indexed by their names, thus those names have to be unique within the blockchain namespace and have to follow specific restrictions. As a result, most of the human readable combinations are already taken, even in a testnet environment. EOSFactory hides the actual names of an EOSIO accounts behind a system of human-friendly aliases.

5. Truly cross-platform

We make sure everything we do is fully compatible with Windows - our toolset enables you to run an EOS node and interact with it on any operating system, including Windows, MacOS and Linux.

Release notes

Please refer to this document.


Our long-term goal is to turn EOSFactory into a comprehensive IDE (Integrated Development Environment) for EOS smart-contracts.


For issues not covered in the documentation there is a dedicated EOS Factory Support channel on Telegram.

Your question is not clear to me. If you refer to the statement from the tutorial InstallingEOSFactory:

EOSIO deployed in Docker is NOT supported.*.

Here we communicate that EOSIO executable has to be installed in the system directly, and not as a Docker image.

We do not like Docker because WSL (Windows System Linux) does not support it. However, we can consider meeting demand from Linux System users, if we see such.
