    async function connectMetaMask() {
        try {
            // Request account access
            await window.ethereum.request({ method: 'eth_requestAccounts' });
            const accounts = await web3.eth.getAccounts();
            console.log('Connected account:', accounts[0]);
        } catch (error) {
            console.error('User  denied account access:', error);
        }
    }

    connectMetaMask();
} else {
