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 ...
