# Deploying Your First Smart Contract with Remix

Smart Contracts are written in Solidity, a statically-typed programming language designed for Ethereum and other EVM-compatible chains. This tutorial uses [Remix](https://remix.ethereum.org/#lang=en\&optimize=false\&runs=200\&evmVersion=null), a browser-based IDE that requires minimal setup.

**1.Open Remix IDE:** Navigate to [Remix](https://remix.ethereum.org/).

**2.Create a New Contract:** In the workspace, create a new file with the ".sol" extension, e.g., "MyFirstContract.sol".

**3.Code a Basic Contract:**

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

contract MessageContract {
    string private message;

    function writeMessage(string calldata newMessage) public {
        message = newMessage;
    }

    function readMessage() public view returns (string memory) {
        return message;
    }
}
```

Remix automatically compiles the contract when saved. Ensure there are no compilation errors.

**4.Compile Manually (Optional):** Click the "Advanced Configurations" tab and select the Solidity version `london`.

**5.Deploy the Contract:** Click the "Deploy" icon logo (it looks like an Ethereum logo with an arrow pointing to the right).

**6.Configure Deployment:**

* Select the basic contract.
* Under "Environment," choose "Injected Provider - MetaMask."
* Connect Remix to MetaMask.

**7.Initiate Deployment:** Click "Deploy" and confirm the MetaMask transaction.

**8.Interact With Your Contract:**

Step1: After deployment, find your contract under "Deployed Contracts."

Step2: Expand the contract and call `writeMessage` by entering a message and clicking the button.

Step3: Confirm the MetaMask transaction.

**Step4: Read the Message:**

Click the blue "readMessage" button to read the on-chain message.

Now you've successfully deployed and interacted with your first smart contract using Remix and MetaMask.
