ERC20-Tokenisation

A bunch of smart contracts deployed on ropsten test, used for implementing capped erc20 standard fungible tokens. Also included is a shitty react frontend to whitelist wallet address and buy tokens.

Running this project

Local setup

To run this project locally, follow these steps.

1. Clone the project locally, change into the directory, and install the dependencies:

git clone https://github.com/akhilmantha/ERC20-Tokenisation.git

cd ERC20-Tokenisation 

# install using NPM 
npm install

2. Start the local Ganache GUI or Ganache CLI and check the network_id of your ganache node and config in truffle_config.

ganache

3. With ganache running, compile and deploy the contracts to the ganache local network in a separate terminal window using truffle

truffle compile

truffle migrate --network ganache_local

4. Running Tests

truffle develop

truffle test

5. Start the app

cd client

npm run start 

Configuration

To deploy to Ropsten test or main networks, replace the url and mnemonics in network config in truffle-config.js Use a burner wallet's mnemonics and not an actual one.

// Create a test project on infura.io and select the network, use that url in the network config. 
const path = require("path");
require("dotenv").config({path: "./.env"});
//HDWalletProvider is used to sign off transactions based on the provided mnemonic
const HDWalletProvider = require("@truffle/hdwallet-provider");
// Based on the amount of test ether you have , provide the account index accordingly. 
const AccountIndex = 1;
// change this according to your infura prject id. 
const {GANACHE_LOCAL, GOERLI_INFURA, ROPSTEN_INFURA, MNEMONIC} = process.env;

module.exports = {
  // See <http://truffleframework.com/docs/advanced/configuration>
  // to customize your Truffle configuration!
