Begin by defining the purpose of your smart contract. What task or agreement will it automate? For this example, let’s consider a basic smart contract for a crowdfunding campaign.

					// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

contract Crowdfunding {
    address public owner;
    uint public goal;
    uint public balance;
    constructor(uint _goal) {
        owner = msg.sender;
        goal = _goal;
        balance = 0;


This code defines a simple smart contract for crowdfunding. It includes the contract’s owner (the address that deploys the contract), the funding goal, and the current balance.

Step 2: Constructor Function

In the code, you’ll find a constructor function that initializes the contract with the owner’s address and the funding goal. The msg.sender variable represents the address that deploys the contract. The balance is initially set to 0.

In the upcoming sections, we’ll explore additional features and functionality you can add to your smart contract code. Writing smart contracts is both an art and a science, and this example is just the beginning.

Compiling and deploying a smart contract

Once you’ve written the code for your smart contract, the next crucial steps are compiling the code and deploying the contract onto a blockchain network. This section will guide you through the process of turning your code into a functional smart contract.
