以太钱包怎么用

// 连接到MetaMask
if (typeof window.ethereum !== 'undefined') {
    ethereum.request({ method: 'eth_requestAccounts' })
        .then(accounts => {
            const account = accounts[0];
            console.log('Connected account:', account);

            // 发送以太币
            ethereum.request({
                method: 'eth_sendTransaction',
                params: [{
                    from: account,
                    to: '0xRecipientAddress',
                    value: '0xAmountInWei' // 例如：'0x2386F26FC10000' 表示0.1 ETH
                }]
            }).then(transactionHash => {
                console.log('Transaction hash:', transactionHash);
            }).catch(error => {
                console.error('Error sending transaction:', error);
            });
        }).catch(error => {
            console.error('Error connecting to MetaMask:', error);
        });
} else {
    console.log('MetaMask is not installed');
}
