🚀 Deploy Your First Smart Contract

Ready to put your code on the blockchain? Deploying a smart contract is simpler than you think! You'll write, compile, deploy, and interact with your first contract—all in this module.

💡 What You'll Learn

📝
Write a Simple Contract
Learn Solidity basics: variables, functions, and state management.
⚙️
Compile with Remix
Use Remix IDE to compile Solidity into EVM bytecode.
🚀
Deploy to Testnet
Send your contract to Sepolia testnet (free test ETH!).
🔗
Interact & Verify
Call functions, read state, and verify contract on Etherscan.

🎯 What We'll Deploy

SimpleStorage Contract
// Store and retrieve a number
contract SimpleStorage {
uint256 public storedData;
function set(uint256 x) public {
storedData = x;
}
}
•
Purpose: Store a single number on blockchain
•
Functions: set() to write, storedData to read
•
Cost: ~50,000 gas to deploy, ~25,000 gas to update

⚡ Why Deploy Your Own Contract?

🎓
Understand Deployment
Go from theory to practice. See how bytecode becomes live code on blockchain.
💪
Build Confidence
Once you deploy one contract, you can deploy anything. Start your Web3 dev journey!
🔓
Unlock DApp Development
Every dApp needs smart contracts. This is your first step to building decentralized applications.
🎯
Learn Gas Optimization
