 dapp唤起metamask登录(类似以太猫)。

matemask钱包是浏览器插件钱包,近期因为存在安全问题,系统进一步升级。

在11月2日钱包将更新开发”隐私模式“设置,用户设置隐私模式后,需要授权某站点才可获取到web3js对象。

当前测试自定义钱包安装:

<script>

window.addEventListener('load', async () => {

// Modern dapp browsers...

if (window.ethereum) {

window.web3 = new Web3(ethereum);

try {

// Request account access if needed

await ethereum.enable();

alert(web3.eth.coinbase);

// Acccounts now exposed

web3.eth.sendTransaction({/* ... */ });

} catch (error) {

console.log(error);

// User denied account access...

}

}

// Legacy dapp browsers...

else if (window.web3) {

window.web3 = new Web3(web3.currentProvider);

// Acccounts always exposed

web3.eth.sendTransaction({/* ... */ });

}

// Non-dapp browsers...

else {

console.log('Non-Ethereum browser detected. You should consider trying MetaMask!');

}

});
