General info

The purpose of this project was for me to understand the components and functionality of a ERC20 token contract.

Technologies

• Truffle - v5.1.58
• Solidity - 0.8.1
• Node - v10.16.3
• Web3.js v1.2.9

Setup

In order to demo this project, please do the following:

• $ git clone this repository to your local machine Install Truffle and Ganache on your local machine
• Open Ganache and connect a workspace to the truffle-config.js file in the project directory
• In the project root directory, run $ truffle migrate to deploy the token contract to your Ganache local node
• Once the contract has successfully deployed, you can use Truffle's console to interact with the deployed contract

Code Examples

Example of contract interaction via Truffle console:

• let instance = await MatthewToken.deployed()
• instance.transferFrom('0x7D9D6fE36E1525dd0854BC9DFFFaA171580ABfFf', '0x8Af28DaeA7BBeEAF561695c5bAdCaa9163897f64', 1000)

Features

List of features ready:

• Query the total supply of tokens in circulation
• Query the balance of tokens that a given address owns
• Approve an address to spend a given amount of tokens on the contract owner's behalf
• Transfer tokens safely between addresses

Status

Project is: in progress
