Metamask issue: window.ethereum.request({ method: "eth_requestAccounts" }) not opening

As a web developer using React, you’ve probably experienced frustration when trying to interact with the MetaMask wallet. The problem lies in how Metamask integrates with the browser’s web platform. This article explains the problem and suggests a solution.

Problem: window.ethereum.request({ method: "eth_requestAccounts" }) not opening

When you click the button to launch window.ethereum.request({ method: "eth_requestAccounts" }), it attempts to execute a request. However, this request does not seem to open MetaMask correctly.

Why the request does not open

The reason for this issue is that window.ethereum.request() expects a specific URL as an argument, which MetaMask uses to connect to your browser. The given method name "eth_requestAccounts" does not match the actual request to MetaMask when you click the button.

Solution: window.ethereum.send({ method: 'eth_requestAccounts' })

To resolve this issue, you need to use the correct function that matches your request. The send() method is used to send requests to the Ethereum network. In this case, you are trying to get an account from MetaMask.

Here’s how to modify your code:

import React, { useState } from "react";
import window from 'window';
import { ethers } from @metamask/dapps;
function App() {
const [account, setAccount] = useState('');
// Get the user's Ethereum account address
const getAccount = async () => {
try {
const accounts = await window.ethereum.request({ method: "eth_requestAccounts" });
if (accounts.length > 0) {
setAccount(accounts[0].address);
}
} catch (error) {
console.error(error);
}
};
// Button to initiate an account request
const handleButtonClick = () => {
getAccount();
}
return (
Get User Account
{account? (
Account: {account}
) : null}
);
}
Export Default Application;

Changes Made

We have made the following changes to our code:

• We replaced window.ethereum.request({ method: "eth_requestAccounts" }) with window.ethereum.send({ method: 'eth_requestAccounts' }).

• We use the correct URL in the `getAccount()’ function to request MetaMask.

• Once we have the user’s account address, we display it on the page.

After making these changes, you should now be able to get an Ethereum account from Metamask when you click the button.
