_Dive into the world of Solidity and smart contracts with this beginner-friendly tutorial._

---

Ethereum has taken the world by storm, revolutionizing the way we interact with decentralized applications and giving birth to the concept of smart contracts. You might be eager to dive into the world of smart contract development, but contracts can be wildly complex. Taking a step back, I want to focus on dialing simple smart contracts to get familiar with syntax.  This article will guide you to writing a simple storage contract that demonstrates how to store and retrieve data on the Ethereum blockchain.

**note: this smart contract does nothing of value lol**

## Introducing the Simple Storage Contract

A Simple Storage contract is a basic Solidity contract that showcases the fundamentals of smart contracts by storing a value on the Ethereum blockchain and allowing users to retrieve it. This tutorial is perfect for those who are new to Ethereum development or looking to solidify their understanding of smart contracts.

## Building the Simple Storage Contract

Let's start by breaking down the Simple Storage contract code:

```solidity
pragma solidity ^0.8.0;

contract SimpleStorage {
    uint256 private storedData;

    function set(uint256 value) public {
        storedData = value;
    }

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

Here, we've defined a contract named `SimpleStorage` with a state variable `storedData` to hold a `uint256` value. The contract has two functions, `set` and `get`, which allow users to store and retrieve the value, respectively.

## Deploying and Interacting with the Simple Storage Contract

To deploy and interact with the Simple Storage contract, I recommend using the Remix IDE, an online development environment for Ethereum smart contracts, but in the future I'll introduce you to deploying and testing locally!

1. Visit [Remix IDE](https://remix.ethereum.org/).
2. Create a new file named "SimpleStorage.sol" and paste the contract code.
3. Compile the contract by navigating to the "Solidity Compiler" tab in the left panel and clicking "Compile SimpleStorage.sol."
4. Switch to the "Deploy & Run Transactions" tab.
5. Select the "Injected Web3" environment to connect Remix to your MetaMask wallet.
6. Click "Deploy" to deploy the contract, and confirm the transaction in MetaMask.
7. Once deployed, the contract will appear under "Deployed Contracts," and you can interact with the `set` and `get` functions.

## Next Steps in Your Web3 Journey

Congratulations on creating, deploying, and interacting with a simple storage contract on the Ethereum blockchain! This foundational knowledge will serve as a stepping stone for more complex smart contract development and interactions.

As you continue your journey as a Web3 developer, explore more advanced contract functionality and experiment with different use cases. With a vast world of decentralized applications waiting to be built, the possibilities are endless. Keep learning, experimenting, and growing your skills, and soon you'll be creating your own innovative smart contracts and decentralized applications. Good luck, and happy coding!
