1. Lifi目前的问题 Lifi由于过量的访问导致无法实现跨链桥的访问，本教程现在通过合约调用Lifi智能合约进行交互。 2. 访问Lifi测试网 由于Lifi智能合约需要相应的参数才能够运行，我们这里需要访问一下的地址: USDT代币我们使用下面的命令在命令行中请求, 这里我们需要讲fromAddress地址换成各位的地址: curl --request GET --url 'https://staging.li.quest/v1/quote?fromChain=5&toChain=59140&fromToken=0x41e5e6045f91b61aacc99edca0967d518fb44cfb&toToken=0x7823E8DCC8bfc23EA3AC899EB86921f90e80F499&fromAddress=0x9fa45Ac2A676cdeE77df20766D4F7D2C04cc9305&fromAmount=10&slippage=0.01&allowBridges=&allowExchanges=' --header 'accept: application/json' > 1.txt 在命令行输入上面的命令后，我们保存在1.txt文件中: 图1 上面表示我们请求成功了 接下来，我们在命令行输入: open . 这个时候我们就可以打开我们的文件目录了： 图2 我们现在打开文件1.txt，可以得到如下的内容:

我们将最后的data的几行复制下来: 图3 可以得到下面的内容: {

这个是我们内容必须的，我们稍后会用到。 接下来我们需要访问 https://goerli.etherscan.io/address/0xfad6367E97217cC51b4cd838Cc086831f81d38C2#writeContract 这里我们可以看到下面的内容: 然后点击“connetct to web3” 我们可以看到下面的： 然后找到这个第7个函数,在第一个位置输入 0x1231DEB6f5749EF6cE6943a275A1D3E7486F4EaE 第二个位置输入10000000000000000，点击write 这里点击确认： 然后找到第3个，就是下面的函数： 第一个位置输入0x1231DEB6f5749EF6cE6943a275A1D3E7486F4EaE 第二个位置输入10000000000000000 然后点击write，然后确认 选择最大，然后点击下一步： 点击批准，等待确认成功。 复制下面的代码: const ethereumButton = document.querySelector('.enableEthereumButton'); const sendEthButton = document.querySelector('.sendEthButton'); let accounts = []; // Send Ethereum to an address sendEthButton.addEventListener('click', () => { ethereum .request({ method: 'eth_sendTransaction', params: [ {

], }) .then((txHash) => console.log(txHash)) .catch((error) => console.error(error)); }); ethereumButton.addEventListener('click', () => { getAccount(); }); async function getAccount() { accounts = await ethereum.request({ method: 'eth_requestAccounts' }); } 上面data那一部分是我们前面请求的内容，需要替换成你自己的。 然后在相同目录中写html页面，这里需要首先安装metamask的相关插件，具体内容可以查看一下的内容： https://docs.metamask.io/wallet/how-to/send-transactions/ 安装好metamask之后，可以可以写如下代码: <button class="enableEthereumButton btn">Enable Ethereum</button> <button class="sendEthButton btn">Send ETH</button> 点击Send ETH即可。 3. 联系与捐赠 如果有问题，可以联系我 https://twitter.com/jackson63891075 如果觉得我写的不错，可以打赏哟: ETH： 0x0290e9cE53972B7a9cC59cCc11224DfB16612271 BSC: 0x0290e9cE53972B7a9cC59cCc11224DfB16612271
