Here’s an article on how to retrieve all accounts from Metamask that connected to your website using Web3 and Chrome extension:

Getting All Accounts Connected to Your Website with Metamask

Metamask is a popular cryptocurrency wallet that allows users to store, send, and receive funds securely. When you connect Metamask to your website using the Chrome extension, it stores the account information locally on your user’s device. However, if you want to retrieve all accounts connected to your website programmatically, you can use Web3.js to fetch the account data.

Step 1: Set up MetaMask and Web3.js

First, make sure you have Metamask installed on your Chrome extension. You can install it from the Chrome extensions page. Once installed, create a new Web3.js instance by setting up an Ethereum provider:

const web3 = new Web3(new Web3.providers.HttpProvider('

Replace YOUR_PROJECT_ID with your current Infura project ID.

Step 2: Request Account Information

Use the ethereum.request() method to request account information from Metamask. This method returns an array of accounts that are connected to the Ethereum network:

ethereum.request({

method: 'eth_accounts',

});

This will return an empty array, indicating that there are no connected accounts.

Step 3: Fetch Account Information

If you want to retrieve account information for specific accounts, use the ethereum.query() method. You can pass a callback function to fetch the account data:

ethereum.onaccountconnect((accounts) => {

console.log(accounts);

});

This will log an array of connected Ethereum accounts.

Example Code

Here’s an example code snippet that demonstrates how to retrieve all accounts connected to your website using Web3.js and Metamask Chrome extension:

const web3 = new Web3(new Web3.providers.HttpProvider('

const accounts = [];

ethereum.request({

method: 'eth_accounts',

})

.on('accounts', (accounts) => {

console.log(accounts);

accounts.forEach((account) => {

accounts.push(account.address); // Add the account address to the array

});

});

ethereum.onaccountconnect((accounts) => {

console.log(accounts);

});

Replace YOUR_PROJECT_ID with your current Infura project ID.

Note

Retrieving account information may require permission from users, and it’s essential to comply with local laws and regulations regarding user data. Additionally, if you plan to use this code in a production environment, consider implementing proper error handling and security measures.

By following these steps, you can retrieve all accounts connected to your website using Web3.js and Metamask Chrome extension.
