Hello World style starter project. Deploys a smart contract with a message, and renders it in the front-end. You can change the message using the interact panel!
This dapp implements a "Hello World" style application that echoes a message passed to the contract to the front end. This tutorial is intended to be followed using the online IDE available at .
Setting up
Remix IDE is an online IDE to develop smart contracts.
If you’re new to Remix, You’ll first need to activate two modules: Solidity Compiler and Deploy & Run Transactions.
Search for 'Solidity Compiler' and 'Deploy & Run Transactions' plugins in the plugin tab in Remix.
Activate the two plugins
Select Solidity Environment
Copy/Paste the Smart contract below into the newly created file HelloIgnite.sol
Copy
Go to Solidity Compiler.
Select Compiler Version to 0.8.10.
Now, Compile HelloCtex.sol
Now, We have to deploy our smart contract on CTEX Chain network. For that, we have to connect to web3 world, this can be done by using Metamask.
Please follow this tutorial to setup a Metamask Account.
Open Metamask and select Add Network from the networks dropdown.
Put in a Network name - “CTEX Testnet”
Enter the Chain ID: 72152
Go ahead and click save
Copy your address from Metamask
Now, let's Deploy the Smart Contract on CTEX Chain:
Select Injected Web3 in the Environment dropdown and your contract
Accept the Connection Request!
Once Metamask is connected to Remix, the ‘Deploy’ transaction would generate another Metamask popup that requires transaction confirmation.
Congratulations! You have successfully deployed HelloIgnite Smart Contract. Now you can interact with the Smart Contract.
The first and foremost step is to flatten the solidity contract into a single file.
Flatten your solidity contract
Flatten using command
sol-merger \"./contracts/*.sol\" ./build
Verifying Contract on CTEXscan
Select Solidity (Single File) in compiler type
Select appropriate compiler version
Choose the license type of your contract
Onto the next section, paste your flattened contract here.
If you had enabled optimization then adjust the optimization section accordingly.
Constructor arguments should have been filled in automatically, if not, they can be retrieved from the trailing bytes of the deployment transaction, they resemble something like 0000000000000000076172d1a6fa476172d1fb5f76172d178d61b04b0ecd319c
If you have followed the process successfully, the contract would be verified.
Go to File Explorers, and Create a new file , Name it HelloIgnite.sol
The first line, pragma solidity ^0.8.10 specifies that the source code is for a Solidity version greater than 0.8.10. are common instructions for compilers about how to treat the source code (e.g., pragma once).
In URL field you can add the URL as
(Optional Fields) Symbol: "CTEX" and Block Explorer URL: "
Head over to and request test CTEX - you will need this pay for gas on CTEX Chain.
Check the deployment status here:
Install or
Navigate to your contract's page and then click verify and publish
