Metamask: Is there any way to test ethereum application using real addresses by Metamask?

Testing of Ethereum apps with real addresses using Metamask

As the creator of React and Solidity based on Ethereum, you are probably familiar with the challenges of a smart contract. One common problem is that consumers can only communicate with their addresses, making it difficult to try programs without the ability to use the real world Ethereum wallets.

However, there is a solution: Metamask, a popular web browser extension, allows you to use a Metamask wallet to interact with Ethereum. In this article, we will investigate whether it is possible to try the Ethereum program written by React and Solidity using real addresses from the WEKEY network (decentralized network) and your Metamask wallet.

What is a metamatic?

Metamk is a browser extension that allows users to protect, send and accept ether (ETH) Ethereum Blockchain. By installing the MetamKK, you can access your MetamKK wallet from any web page, allowing you to communicate with your Ethereum address. This feature has facilitated developers to create decentralized programs (DAPPS), and there is no need to set up a separate wallet or infrastructure.

Test of Ethereum program using Metamask

To check the Ethereum program written by React and Solidity, using the actual Vinkuey network addresses, you can do the following steps:

• Make sure it is determined as a default wallet.

• Then import Web3.js into your program and configure the contract code to use a copy of the Web3.

• Imported Metamk wallet and address

  

  : Import the Metamask purse and many real addresses from the Walkboey network in your React components using a “Hook” or similar.

• You can do this by transferring the wallet address as an argument to a function that allows the connection, such as “Web3.eth.connect ().

• Try the program : When connected, you can communicate with your application smart contract using the "contract" copy provided by Web3.js.

CODE EXAMPLE

Here are some examples of code to start:

Jsx

import to respond from “respond”;

Imported {ether} from Ether;

// Imported the Metamask purse object and many real addresses from the Walkey network

CONSS WRIGHTWORKADDRESSES = [

{

Address: “0x … Mscasey Address …”,

Network: “Rinkeby”,

},

]

Function Program () {

CONST [Contract, SetContract] = React.Ustate (NUL);

to useFect (() => {

// Login to Metamask’s wallet

CONST CONNECTWALLET = Async () => {{{{

try {

// Get the current Ethereum address from the Metamask Wallet object

CONST CURRENTADDRESS = waiting for ether.ghenamedaccount ();

Let Realaddress;

rinkeeynenetworkaddresses.freach ((address) => {

If (Currentaddress.address.tolderCase () == address.address.topowercase ()) {

Reladdress = address;

break;

}

});

// Login to Ethereum network using Metamask wallet

SetContract (Ethers.connect (‘Rinkeby’, Currentaddress));

Return Reladdress;

} catch (error) {

console.error (error);

}

};

Connectowallet ();

}, []);

// Try the contract using Web3.js

CONSTS TESTFUNCTION = Async () => {

// Define a simple function to check the program

the result of the CONST = wait for the contract.executescript ({{{{{{{{{{{{{

Code: “Back” test result! ‘;

});

console.
