Token smart contract

Creating a token on top of Ethereum with Vyper is easy. Let's follow the initial steps to prepare our development environment before we build a token.

Start by ensuring that you have geth installed and that the geth program is in the $PATH environment variable (meaning that you can call geth without its full path):

$ virtualenv -p python3.6 token-venv
$ source token-venv/bin/activate
(token-venv) $ pip install eth-abi==1.2.2
(token-venv) $ pip install eth-typing==1.1.0
(token-venv) $ pip install py-evm==0.2.0a33
(token-venv) $ pip install web3==4.7.2
(token-venv) $ pip install -e git+https://github.com/ethereum/populus#egg=populus
(token-venv) $ pip install vyper
(token-venv) $ mkdir token_project
(token-venv) $ cd token_project
(token-venv) $ mkdir tests contracts
(token-venv) $ cp ../token-venv/src/populus/populus/assets/defaults.v9.config.json project.json
