I can walk you through this process, but first I need to clarify a few things.

What are DApps (decentralized applications)?

DApps are applications built on blockchain networks like Ethereum, Polkadot, or Solana. They run on decentralized protocols and allow users to interact with each other without relying on central authorities like wallets.

Can you build a DA app without MetaMask?

Yes, it is possible to build a DApp that doesn’t use MetaMask at all. However, you will need to choose an alternative method for authenticating users and interacting with the blockchain.

Here are a few popular options:

• Mist (formerly MetaMask): While Mist provides access to the Ethereum blockchain, you can still build a custom application without using it directly.

• Ledger Wallet: You can use Ledger Wallet as a central authority and interact with the blockchain via a web interface or mobile app.

• Ethereum CLI

  

  : The eth-cli package allows you to run Ethereum contracts from the command line, which can be used to interact with the blockchain without a wallet.

Now let’s dive into creating a DA application that doesn’t use MetaMask at all.

Step 1: Choose an EVM-based framework

To build a DApp, you need to choose an EVM (Ethereum Virtual Machine) framework that allows you to run Ethereum contracts. Some popular options include:

• Ethereum.js: A JavaScript library that provides an easy way to interact with the blockchain.

• Truffle Suite: An integrated development environment (IDE) for building, testing, and deploying DApps on the Ethereum network.

This example uses “Ethereum.js”.

Step 2: Configure the EVM Framework

Install “ethers.js” (previously “web3.js”) as a dependency in your project:

npm install ethers.js

Then create a new file called “index.js” and add the following code to configure your EVM framework:

const Web3 = require('ethers.js');
// Create a new Ethereum provider (e.g. local machine or remote node)
const provider = new Web3.providers.WebsocketProvider("wss://example.com/webSocketUrl");
// Get an instance of the provider and sign it with your private key
const web3 = new Web3(provider);
// Define the EVM framework
const myEthers = new Ethers.Contract('ABI of the contract', 'Source code of the contract');

Replace “Agreement ABI” with the actual name of the contract you want to connect to, and “Agreement Source Code” with the source code for that contract.

Step 3: Define the functionality of your DApp

Create a new file called “Contract.js” (or any other file that contains the contract code) and add the following code:

pragma power ^0.8.0;
contract MyDapp {
public address centralEthereumAddress = "0x...your-central-ethereum-address..."; // Replace with your centralized Ethereum address
function callFunction() public payable {
// Call the contract function with the argument to be paid (e.g. transfer ether)
myEthers.transfer(centralEthereumAddress, 1 ether);
}
}

Replace “MyDapp” with the actual name of your DApp contract.

Step 4: Use the EVM framework in your React app

Now that you have configured your EVM framework and defined the functionality of your DApp, you can use it in your React application. Here’s an example:

import React from 'react';

import ReactDOM from "react-dom";

import { ethers } from './Contract';


function App() {

  return (

    

      
MyDapp

       ethers.callFunction()}>Call Function
