2. Modules

Basic modules of Remix IDE are File Explorer, Plugin Manager and Editor

File Explorer

File Explorer icon is at the top.

File Explorer

Plugin Manager

Remix IDE is run based on the plugin. To use various features, module needs to be activated by plugin admin. Icon pannel's basic module is File Explorer, compile, deploy and run.

Plugin Manager

Code Editor

In basic pannel, you can write/edit codes. If you are editing the original code, you need to compile again.

Code Editor

Create MEVerseGreeter.sol in directory with Code Editor

// SPDX-License-Identifier: MIT
pragma solidity ^0.5.6;
contract Mortal {
    /* Define Variable owner of the type address */
    address payable owner;
    /* This function is executed at initialization and sets the owner of the contract */
    constructor () public { owner = msg.sender; }
    /* Function to recover the funds on the contract */
    function kill() public payable { if (msg.sender == owner) selfdestruct(owner); }
}

contract MEVerseGreeter is Mortal {
    /* Define variable greeting of the type string */
    string greeting;
    /* This runs when the contract is executed */
    constructor (string memory _greeting) public {
        greeting = _greeting;
    }
    /* Main function */
    function greet() public view returns (string memory) {
        return greeting;
    }
}

Terminal

You can check the result, status, and information of transaction in Terminal. To see more details, click the icon.

Terminal

3. Solidity Compiler

If you have finished writing code, check if there is any error or warning.

Solidity Compiler

4. DEPLOY & RUN TRANSACTIONS

If the contract is compiled, click Ethereum icon in Icon pannel to deploy.

Deploy & Run

• ENVIRONMENT : Setting up development environment. Choose Injected Provider - MetaMask when deploying in MEVerse Network.

• ACCOUNT : Account information that deploys smart contract

• CONTRACT : Contract that you wish to deploy. Only compiled contracts can be selected.

Remix - MetaMask

Injected Provider - MetaMask Integration Screen

Deploy

After checking Environment, Account, and Contract, click Deploy button to deploy contract. After checking the network fee, it completes contract deployment.

MetaMask - Approve for Contract Deployment

You can see whether the contract has been successfully deployed or not by checking and Deployed Contract. Greet button will let you see the results by calling greet function in smart contract.
