HelloWorld-Smart-Contract

This is my first smart contract written in Solidity as part of my Web3 learning journey.
The goal of this project is to understand the basics of smart contracts and start building consistently on GitHub.

🚀 What This Contract Does

• Stores a message on the blockchain
• Initializes the message with "Hello, Web3!"
• Allows anyone to update the message using a public function

🛠 Tech Stack

• Solidity
• Remix IDE (browser-based Ethereum IDE)

🧪 How to Run / Test

1. Open https://remix.ethereum.org
2. Create a new file named HelloWorld.sol
3. Paste the contract code
4. Compile using Solidity version 0.8.x
5. Deploy the contract
6. Call the message() function to read the value
7. Call updateMessage() to change the stored message
