SOLIDITY

Simple Token Contract Project

This project aims to create a simple program that will do the following with said features: (for educational purposes only)

Key Features:

• Token Name: This contract represents an token with the name "MYPRECIOUS."
• Token Symbol: The token is identified by the symbol "MYP."
• Token Balances: It keeps track of user balances using a mapping that associates addresses with token amounts.
• Mint Function: The mint function allows adding tokens to a user's balance, increasing the total token supply.
• Burn Function: The burn function subtracts tokens from a user's balance and decreases the total token supply when the user has enough tokens.

Description

This Solidity program is a simple smart contract for educational purposes, focusing on two core functions: minting (adding) and burning (subtracting) assets. It serves as a practical example for learning about Ethereum smart contract development.

Getting Started

Executing program

To run this program, you can use Remix, an online Solidity IDE. To get started, go to the Remix website at https://remix.ethereum.org/.

Once you are on the Remix website, create a new file by clicking on the "+" icon in the left-hand sidebar. Save the file with a .sol extension (e.g., HelloWorld.sol). Copy and paste the following code into the file:

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.18;

contract MyToken {
    string public coinName = "MYPRECIOUS";
    string public coinSymbol = "MYP";
    uint public totalCoinSupply = 0;
    
    mapping(address => uint) public balances;

    function mint(address user, uint amount) public {
        totalCoinSupply += amount;
        balances[user] += amount;
    }

    function burn(address user, uint amount) public {
        if (balances[user] >= amount) {
            totalCoinSupply -= amount;
            balances[user] -= amount;
        }
    }
}

To compile the code, follow these steps:

1.) Go to the "Solidity Compiler" tab located in the left-hand sidebar.

2.) Ensure that the "Compiler" option is set to "0.8.18" (or a compatible version).

3.) Click on the "Compile Solidity.sol" button to compile the code.

Once the code is successfully compiled, proceed to deploy the contract as follows:

1.)Click on the "Deploy & Run Transactions" tab in the left-hand sidebar.

2.)From the dropdown menu, select the "Solidity" contract.

3.)Click the "Deploy" button to initiate the deployment process.

After deploying the contract, you can interact with its two primary functions:

1.)Use "burn" to subtract Ethereum (ETH) assets.

2.)Use "mint" to add assets, keeping interactions at a high-level for simplicity.
