My First Smart Contract on Ethereum: A Remix Tutorial

🧠 Overview

In this tutorial, I deployed my first Solidity smart contract using Remix IDE. I went from writing a basic storage contract to compiling, deploying, and interacting with it — all without leaving the browser.

🧩 Contract: SimpleStorage.sol

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

contract SimpleStorage {
    uint256 private storedNumber;

    function set(uint256 _num) public {
        storedNumber = _num;
    }

    function get() public view returns (uint256) {
        return storedNumber;
    }
}

🧾 Function Explanation

✅ Step 1: Compile the Contract

• Selected compiler version: 0.8.30

• File: SimpleStorage.sol

• Clicked Compile

🚀 Step 2: Deploy to Remix VM

• Environment: Remix VM (Prague)

• Gas Limit: 3,000,000 (default)

• Clicked Deploy

🧪 Step 3: Interact with the Contract

• Called set(42) to store a value

• Then called get() to retrieve it — ✅ returned 42

📝 What I Learned

• How Solidity functions like view and public work

• How transactions are recorded and gas is calculated

• The Remix IDE flow: write → compile → deploy → test

---

🧱 Challenges Faced

• Remembering to set the correct compiler version

• Understanding Remix's deploy tab (e.g. gas limit, value, etc.)

⛓ What's Next?

• Deploy this to a real testnet like Sepolia or Goerli

• Use MetaMask + Injected Provider

• Add events, ownership, and unit testing with Hardhat
