Development Information


Node >= v6.9.1 and Yarn required.

Before any development, install the required NPM dependencies:



Start Ethereum’s testrpc tool to provide a Web3 interface (leave this running):

yarn testrpc

Compile the latest smart contracts:

yarn compile

Run the testsuite against the simulated network:

yarn test

Make sure to lint the Solidity files once you’re done:

yarn lint

Generating Documentation

Install the dependencies:

cd doxity
cd ..

Autogenerate documentation from Ethereum Natspec using Doxity:

yarn doc

Final output will be written to docs, which will be automatically published on push to GitHub Pages at


Run automated smart contract analysis (requires Oyente and Mythril):

yarn analyze

Flatten contract source (for e.g. Etherscan verification, requires solidity-flattener to be installed):

yarn flatten
