ICO-playground

This repository contains the code for an toy ICO developed as part of a Blockchain programming course.

• Update: With the completion of the 2018 semester, the FunnyToken ICO contracts have been published on the Ropsten testnet. You can buy funny tokens by sending money to the TokenSale contract address.

Organization of the repository

As this course is offered at least once a year to a different class, the actual implementations of each class will remain on branches named <year>_project. The master branch will only contain the basic project structure.

Getting started instructions

The instruction for setting up your development environment can be found here.

ico-playground's Issues

Save Contract address as Environmental variable

During development the contract address changes every time we change it and redeploy.
Change the deployment script to save the address on an environment variable named TOKEN_ADDRESS e SALE_ADDRESS

Add migration code for the TokenSale contract

In order to deploy the TokenSale contract, we need to edit the 2_deploy_contract.js file to specify its deploy whenever truffle migrate is run.

Add tests to the flask application

Add tests to the Flask frontend which tests all functionalities of the site, including buying tokens

Check Web3 Connection string

currently, the Web3 connection is using auto-detection of the private blockchain. Ideally it should use HTTPProvider.

complete the ERC20 contract

The token contract in the contracts directory (FunnyToken) only inherits the ERC20 template of Openzeppelin. Compile and complete the contract until all the compilation warnings disappear and you think the contract is complete.

Modify Dapp to interact with the TokenSale contract

Enhance the frontend code to allow the purchase of tokens via the TokenSale contract

Enable deployment of TokenSale contract

Update contract deployment script to deploy the TokenSale contract as well.

write a constructor method for the FunnyToken contract.

Funny toke needs a contract in order to define the total supply and perhaps some other functionality.

Add rate to the website

The web site has to inform the user whatis the rate ETH/FNT

Write a White paper describing the inner working of the ICO

Create initial Flask App

Create a Flask App to serve as a frontend for our ICO DAPP

Write tests for TokenSale

As done for the FunnyToken contract, write tests for the TokenSale contract

Create initial tests

Adapt tests from metacoin example on truffle documentation to Funnytoken

Replicate interface of the JS frontend in python

replicate the same interface found in the Javascript frontend in the Python frontend

Add QRcode to page

On the Python version we created a QRcode from the contract's address to facilitate the purchase of the token by visitors. Do the same on the JS frontend.

edit truffle.js

Add configuration for deployment on private blockchain

Create Javascript frontend

Create frontend based on Angular 6.x.
