我正在尝试将web3js与Trezor集成到Truffle开发网络或使用Ropsten测试网络中。
想法是使用硬件钱包签署交易，然后使用web3js发送原始交易。
我得到的是我们没有足够的余额来进行交易，可能是因为web3js未将其中一个10个Truffle帐户之一，并且使用的Trezor地址不在我的本地网络中。
在ropsten上，我有一些以太币并且收到“无效地址”。
有没有办法使用Trezor签名交易，使用web3js将其发送到Truffle开发网络？我的意思是，有没有一种方法将Trezor地址包含在Truffle网络中？
Truffle中的情况在此处详细说明，但问题可以概括为“是否有一种方法将硬件钱包包含在Truffle开发网络中？”：https://github.com/trufflesuite/truffle/issues/973
在ropsten上，我成功发送了交易并在回调中收到了交易哈希值，但是如果我们查询该交易，则会发现交易不存在..那么这是怎么回事？
我还尝试在Ropsten中部署合同，并且现在在调用智能合约函数时收到“无效地址”。也许签名功能是错误的吗？有人可以将Trezor交易签名与web3js集成吗？
您们是否看到我们遵循的签名和发送过程中的任何错误？ 可能在处理R、V和S参数时有问题。
另一个重要的事情是我正在使用https://github.com/ethereumjs/ethereumjs-tx创建原始交易

getTrezorConnect函数只是异步获取window.trezorConnect对象，因为该对象被注入为脚本
<script src="https://connect.trezor.io/4/connect.js"></script>
let getTrezorConnect = new Promise(function(resolve, reject) {
// Wait for loading completion
window.addEventListener('load', function() {
let trezorConnect = window.TrezorConnect
return resolve(trezorConnect)
})});
export default getTrezorConnect
