The simplest way to gather informations about the wallet address, balance and the network used from Metmask in Javascript and HTML.
the HTML source code
Recommended by LinkedIn
<html
<head>
<title>Ethereum Wallet</title>
</head>
<body>
<h1 id="address">The Wallet</h1>
<h1 id="network">The Network</h1>
<h1 id="balance">The Balance</h1>
<script src="./script.js">
</script>
</body>
</html>>
and the javascript source code:
const Web3 = require("Web3")
async function connect() {
if (typeof window.ethereum !== "undefined") {
try {
const web3 = new Web3(Web3.givenProvider);
const accounts = await ethereum.request({method: "eth_requestAccounts"});
// get account
const address = accounts[0];
// get network (simple / straightforward / hacky)
const _network = window.ethereum.networkVersion;
const network = _network === "1" ? "mainnet" : _network === "5" ? "goerli" : _network === "11155111" ? "sepolia" : "undefined"
// get balance
web3.eth.getBalance(address, (error, balance) => {
if (error) { console.error(error);}
else {
// display the balance in ETH
document.getElementById("balance").innerHTML = `Balance: ${(balance/10**18)} ETH`;
// display the wallet address
document.getElementById("address").innerHTML = `Address: ${address}`;
// display the network
document.getElementById("network").innerHTML = `Network: ${network}`;
}
});
} catch (error) {
console.log(error);
}
}
}
connect();
;
PS: using Browserify package can resolve the "require" problem you could face when running this code.
