Basic DApp Example
Build a simple DApp that reads data from a deployed smart contract and displays it on a web page.
Building Our First DApp
Welcome to building your first Decentralized Application (DApp)! In this lesson, we'll create a simple DApp that reads a message stored on a smart contract and displays it on a web page.
This example will tie together concepts you've learned about smart contracts and front-end interaction.
The Simple Message Contract
First, let's define the smart contract. This contract will be very basic: it just stores a single string variable, myMessage, which we'll make public so its value can be easily read from outside the contract.
Remember, this contract would be compiled and deployed to a blockchain (like Ethereum).
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;
contract SimpleMessage {
string public myMessage = "Hello CoddyKit DApp!";
