Using Replit

Replit is a coding platform that allows you to write code and host apps. Replit supports Solidity programming language 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 ctex using Replit IDE and Replit Solidity development template (Solidity starter beta)

NOTE:

For additional examples about Solidity with Replit, you can read the article Get started with Replit! or check Replit Solidity documentation and Escrow contract tutorial

Prerequisites

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

You need a browser-based web3 wallet to interact with the ctex 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 ctex Chain:

1. Create a Replit account

2. Download Metamask wallet

3. Configure ctex on Metamask

4. Get testnet tokens

Working with a Repl

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

1. Login or create an account. After creating your Replit account, your home screen will include a dashboard where you can view, create projects, and manage your account

2. Once logged in, create a Solidity starter repl, Select + Create Repl from the left panel or + in the top right corner of the screen

3. Select the Solidity starter (beta) template and give your project a title

4. 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, 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 Ctex Chain

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

1. Click on Run (at the Top) to install all relevant packages, start up the contract deployment UI

2. Connect your MetaMask wallet to the web interface and switch to the ctex Chain Testnet

3. Click on Connect wallet, select your account, then choose Connect

4. From the Drop-down list, Select your contract that you want to deploy

5. Click on Deploy

6. Approve the MetaMask pop-up that appears to confirm the transaction from your wallet to deploy your contract

7. Navigate to ctexcscan 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​

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:

1. Select the project title at the top of the screen.

2. Complete your project name and description and click Publish.
