Get Started

Install Solidity 0.6.0 (Optional)

Ubuntu 18.04:

sudo apt install software-properties-common
sudo add-apt-repository ppa:ethereum/ethereum
sudo apt-get update
sudo apt-get install solc

Mac OS X:

brew update
brew upgrade
brew tap ethereum/ethereum
brew install solidity

Setup Python Environment

python3.7 -m pip install virtualenv
python3.7 -m virtualenv .venv
. .venv/bin/activate

Install PyEosKit

Ubuntu

python3.7 -m pip install https://github.com/learnforpractice/pyeoskit/releases/download/v0.7.0/pyeoskit-0.7.0-cp37-cp37m-linux_x86_64.whl

Mac OS X

python3.7 -m pip install https://github.com/learnforpractice/pyeoskit/releases/download/v0.7.0/pyeoskit-0.7.0-cp37-cp37m-macosx_10_9_x86_64.whl

Install Jupyter Notebook

python3.7 -m pip install notebook

Install Solc Compiler

python3.7 -m pip install py-solc-x

Install Web3

python3.7 -m pip install --pre web3[tester]==5.5.0

Install Base58

python3.7 -m pip install base58

Start a Testnet

rm -r dd
nodeos  --verbose-http-errors  --http-max-response-time-ms 100 --data-dir dd --config-dir cd --wasm-runtime eos-vm-jit --contracts-console -p eosio -e --plugin eosio::producer_plugin --plugin eosio::chain_api_plugin --plugin eosio::producer_api_plugin

In order to pass test_ecrecover and test_sign_with_eth_private_key testcase in evm_test.py, start nodeos with --eos-vm-oc-enable option as show below:

rm -r dd
nodeos --eos-vm-oc-enable --verbose-http-errors  --http-max-response-time-ms 100 --data-dir dd --config-dir cd --wasm-runtime eos-vm-jit --contracts-console -p eosio -e --plugin eosio::producer_plugin --plugin eosio::chain_api_plugin --plugin eosio::producer_api_plugin

Initialize the Testnet

In the same directory, run the following command:

python3.7 testnet-init.py http://127.0.0.1:8888

modify http://127.0.0.1:8888 to the right url if nodeos's http server is not listening at the default ip and port

Run TestCase

In the same directory, run the following command:

python3.7 evm_test.py http://127.0.0.1:8888

modify http://127.0.0.1:8888 to the right url if nodeos's http server is not listening at the default ip and port

Run VMTests

python3.7 testsrunner.py -- --http-server-address http://127.0.0.1:8888 -d VMTests -v 0

Notes:

There are 609 evm tests in VMTests directory, 123 vm tests will throw exceptions from evm as expected, other tests will not throw exceptions as pass the result checking.

Refer to test script in testsrunner.py for how it works.

Interact With EVM4EOSIO Via Ethereum RPC Interface

Python script eth2eosbridge.py enables applications to interact with EVM smart contract on EOSIO through the Ethereum RPC Interface, so that Dapp on Ethereum can be easily ported to the EOSIO platform.

To use this tool run the following command to install required Python packages.

python3.7 -m pip install plyvel
python3.7 -m pip install flask
python3.7 -m pip install flask_cors

Run the following command to start this tool

python3.7 eth2eosbridge.py
