These are the requierments.
/* REQUIREMENTS 1. Your contract will have public variables that store the details about your coin (Token Name, Token Abbrv., Total Supply) 2. Your contract will have a mapping of addresses to accounts (address => uint) 3. You will have a mint function that takes two parameters: an address and a value. The function then increases the total supply by that number and increases the balance of the “sender” address by that amount 4. Your contract will have a burn function, which works the opposite of the mint function, as it will destroy tokens. It will take an address and value just like the mint functions. It will then deduct the value from the total supply and from the balance of the “sender”. 5. Lastly, your burn function should have conditionals to make sure the balance of "sender" is greater than or equal to the amount that is supposed to be burned. */
This Solidity contract defines a simple token system with functions to mint and burn tokens.
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:
Open In Remix Compile Deploy
pragma solidity ^0.8.18;
contract MyToken {
// Public variables to store token details
string public tokenName = "Deku Meaw";
string public tokenAbbrv = "DM";
uint256 public totalSupply = 0;
// Mapping to store balances of addresses
mapping (address => uint256) public balances;
// Events for Mint and Burn actions
event Mint(address indexed to, uint256 value);
event Burn(address indexed from, uint256 value);
// Mint function to increase total supply and balance of the given address
function mint(address _address, uint256 _value) public {
totalSupply += _value;
balances[_address] += _value;
emit Mint(_address, _value);
}
// Burn function to decrease total supply and balance of the given address
function burn(address _address, uint256 _value) public {
require(balances[_address] >= _value, "No balance to burn");
totalSupply -= _value;
balances[_address] -= _value;
emit Burn(_address, _value);
}
}
To compile the code, click on the "Solidity Compiler" tab in the left-hand sidebar. Make sure the "Compiler" option is set to "0.8.4" (or another compatible version), and then click on the "Compile HelloWorld.sol" button.
Once the code is compiled, you can deploy the contract by clicking on the "Deploy & Run Transactions" tab in the left-hand sidebar. Select the "HelloWorld" contract from the dropdown menu, and then click on the "Deploy" button.
Once the contract is deployed, you can interact with it by calling the sayHello function. Click on the "HelloWorld" contract in the left-hand sidebar, and then click on the "sayHello" function. Finally, click on the "transact" button to execute the function and retrieve the "Hello World!" message.
