Token Sale Smart Contract for the BlockFoodToken

BlockFood Token Sale Smart Contract

Goal

The goal of this smart contract is to create and distribute BlockFoodToken according to the rules specified in the whitepaper.

The token sale behaviour is coded into the smart contract itself. Nothing is hidden.

Usage

The BlockFood Token Sale Smart Contract will be deployed on the Ethereum blockchain before the date of the token sale.

Its address will be communicated from the https://blockfood.io website.

Dev

The smart contract has been written in test-driven development using the Truffle framework.

Prerequisite

• Node.js 8+

• Truffle 4.0.1+

npm i -g truffle

Launch tests

In a console, from the base directory of the project, type:

truffle test

This will output something like this:

$ truffle test
