# Using Raplit

[Replit](https://docs.replit.com/tutorials/01-introduction-to-the-repl-it-ide) is a coding platform that allows you to write code and host apps. Replit supports [Solidity programming language](https://replit.com/@replit/Solidity-starter-beta?v=1) so it provides all of the features and functionality for Web3 developers to create and deploy smart contracts.

This article explains how to build and deploy a solidity smart contract on rupto using [Replit IDE](https://replit.com/signup) and [Replit Solidity development template (Solidity starter beta)](https://replit.com/@replit/Solidity-starter-beta?v=1)

**NOTE:**

For additional examples about Solidity with Replit, you can read the article [**Get started with Replit!**](https://blog.replit.com/solidity) or check [**Replit Solidity documentation and Escrow contract tutorial**](https://docs.replit.com/tutorials/33-escrow-contract-with-solidity)

### Prerequisites <a href="#prerequisites" id="prerequisites"></a>

You do not need any local environment to deploy your solidity smart contract on **Rupto Chain** using Replit.

You need a browser-based web3 wallet to interact with the **Rupto Chain Testnet** and deployed contracts. If you are already using **MetaMask**, it is recommended to create a new account for testing with Replit. You can do this from the account menu, which appears when you click on the account avatar in the top right corner of **MetaMask** interface.

You must setup all of the following Prerequisites to be able to deploy your solidity smart contract on Rupto Chain:

* Create a Replit account
* Download Metamask wallet
* Configure Rupto on Metamask
* Get testnet tokens

### Working with a Repl <a href="#working-with-a-repl" id="working-with-a-repl"></a>

Every Repl that you create is a fully functional development and production environment. Follow the steps to create a solidity starter Replit:

* [Login](https://replit.com/login) or [create an account](https://replit.com/signup). After creating your [Replit account](https://docs.replit.com/tutorials/01-introduction-to-the-repl-it-ide), your home screen will include a dashboard where you can view, create projects, and manage your account
* Once logged in, create a Solidity starter repl, Select **+ Create Repl** from the left panel or **+** in the top right corner of the screen
* Select the [**Solidity starter (beta)**](https://replit.com/@replit/Solidity-starter-beta?v=1) template and give your project a title
* Click on **+ Create Repl** to create your project

**NOTE:**

The Solidity starter repl comes with a friendly web interface, built using the [**web3 Ethereum JavaScript API**](https://web3js.readthedocs.io/en/v1.5.2/), which you can use to deploy and interact with our contracts. We will deploy to Replit’s testnet, a custom version of the Ethereum blockchain managed by Replit and optimised for testing.

### Deploy on Rupto Chain <a href="#deploy-on-polygon" id="deploy-on-polygon"></a>

Make sure that you have followed the list of Prerequisites above so that you are ready to deploy and interact with your smart contract:

* Click on **Run** (at the Top) to install all relevant packages, start up the contract deployment UI
* Connect your MetaMask wallet to the web interface and switch to the **Rupto Chain Testnet**
* Click on **Connect wallet**, select your account, then choose Connect
* From the Drop-down list, Select your contract that you want to deploy
* Click on **Deploy**
* Approve the MetaMask pop-up that appears to confirm the transaction from your wallet to deploy your contract
* Navigate to **ruptoscan** to search for your account, view your deployed contract, and copy your account address

Once your contract have been deployed, it will show up as expandable boxes below the drop-down box. Expand it and take a look at all the different functions available. You can now interact with your contract using the provided user interface or from a sharable URL shown on the interface.

### Publish to Replit​ <a href="#publish-to-replit" id="publish-to-replit"></a>

Replit allows you to publish your projects to a personal profile. After publishing, projects will show up on your spotlight page for others to explore, interact with, clone, and collaborate.

Follow the steps to publish to Replit:

* Select the project title at the top of the screen.
* Complete your project name and description and click Publish.
