Prototype Ethereum Smart Contracts in Python

Prototype Ethereum Smart Contracts in Python

Description

Library with base classes to prototype Ethereum Smart Contracts in Python. This includes:

• wadray: classes for fixed number of decimals math implemented with integers.

• contracts: classes to simulate contracts in Python with features like rollback on exception, external methods, views. Also classes for common contracts like ERC20 (tokens), ERC721 (NFTs) and AccessControl.

• brwrappers: classes to wrap ethereum contracts called thru [brownie](https://github.com/eth-brownie/brownie/) but with a pythonic interface

• w3wrappers: classes to wrap ethereum contracts called thru [web3py](https://web3py.readthedocs.io/) but with a pythonic interface

Tox Tests

The tox tests run in three variants:

• default: only uses and tests the prototype libraries, no blockchain.

• default-w3: users and tests two variants: prototype and w3wrappers (wrappers using web3py).

• default-br: users and tests two variants: prototype and brwrappers (wrappers using brownie).

It’s not possible for now running all the tests together because of incompatibilities between brownie and web3[tester].

To run the tox default-br tests, you need an environment with Brownie, SOLC and other requirements.

You can do it using a Docker image an a few commands

docker run -it -v $PWD:/code -w /code gnarvaja/eth-dev:1.0.0 bash
gnarvaja/eth-dev:eth-proto-brownie
pip install tox
brownie pm install OpenZeppelin/openzeppelin-contracts@4.3.2
brownie pm install OpenZeppelin/openzeppelin-contracts-upgradeable@4.3.2
tox -e py39-br

docker run -it -v $PWD:/code -w /code gnarvaja/eth-dev:eth-proto-brownie bash
tox -e py39-br
