我尝试将 web3js 与 Trezor 集成到 truffle 开发网络或使用 ropsten测试网络。
我们的想法是使用硬件钱包签署交易，然后使用web3js发送原始交易
我得知我们没有平衡来进行交易，可能是因为web3js没有使用10个松露帐户中的一个并使用不在我本地网络中的trezor地址 ..
在ropsten上我有一些醚，我得到了＃34;无效的地址＆＃34;
有没有办法使用web3js将已签名的交易（使用trezor）发送到松露开发网络？我的意思是，有没有办法将trezor地址包含在松露网络中？
松露的情况在这里详细解释，但问题可以推广到＆＃34; 有没有办法将硬件钱包纳入松露开发网络？＆＃34; ：https://github.com/trufflesuite/truffle/issues/973
使用ropsten我已经设法发送一个事务并在回调中接收一个事务哈希，但是如果我们查询该事务，我们得到该事务不存在..那么......这怎么可能？
我也试过将合同部署到Ropsten，现在我得到了＃34;无效的地址＆＃34;在调用智能合约功能时。也许签名功能错了？有人可以将Trezor交易登录与web3js集成吗？
你们看到我们所遵循的签名和发送过程中有什么问题吗？ R，V和S参数处理可能有问题 ..
另一个重要的事情是我使用https://github.com/ethereumjs/ethereumjs-tx来创建原始交易
在web3js，truffle和trezzor中发布的问题可以提供更多信息：

好吧，经过大量的尝试，我们设法将与Trezor签署的原始交易发送到 Ropsten ，松露（请参阅答案底部的编辑）还有一个本地的私人 Geth 网络，因此代码没问题，Trezor在这些环境中的集成没有问题
https://ropsten.etherscan.io/address/0x89e2c46b22881f747797cf67310aad1a831d50b7
为了能够将已签名的事务发送到Ropsten testnet，我已经更改了这些内容。
这假设您已将合同部署到Ropsten并且您拥有合同地址。
1）获取Trezor帐户的地址
getTrezorAddress = async() => {
let trezor= await this.getTrezor();
// spend one change output
let address_n = "m/44'/1'/0'/0/0";
trezor.ethereumGetAddress(address_n, function (result) {
if (result.success) { // success
console.log('Address: ', result.address);
} else {
console.error('Error:', result.error); // error message
}
});
}
2）将trezor地址放入原始事务的from字段中，通过获取该地址的事务计数来获取事务的nonce。重要提示：使用getTransactionCount上的“pending”可选参数来获取帐户的所有交易，否则您将重写未决交易。
getNonce = async(address) => {
let web3 = await this.getWeb3();
return new Promise (function (resolve,reject) {
web3.eth.getTransactionCount(address, "pending", function (error,result){
console.log("Nonce "+result);
resolve(result);
});
});
}
let count = null;
await this.getNonce("0xedff546ac229317df81ef9e6cb3b67c0e6425fa7").then(result => {
if(result.length % 2 !==0){
result = "0"+result;
}
count = "0x"+result;
});
let tx = {
nonce: count ,
gasPrice: web3.toHex(gasPriceGwei*1e9),
gasLimit: web3.toHex(gasLimit),
to: CONTRACT_ADDRESS,
value: '0x00',
data: getData,
chainId:chainId,
from:"yourTrezzorAddress"
};
3）r，s，v参数不正确，处理它们的正确方法是获取trezor响应的值并将其转换为hexa：
// response is the Trezor sign response
tx.v= response.v;
tx.r="0x"+response.r;
tx.s="0x"+response.s;
let ethtx = new ethereumjs(tx);.
const serializedTx = ethtx.serialize();
const rawTx = '0x' + serializedTx.toString('hex');
//finally pass this data parameter to send Transaction
web3.eth.sendRawTransaction(rawTx, someCallbackFunction);
重要提示：ropsten中的挖掘时间将介于15到30秒之间，因此如果在someCallbackFunction中使用散列检查事务接收，则结果将为null，因为事务处于挂起状态。 / p>
4）要在ropsten进行测试，我们使用Infura，因此我们更改了web3提供商：
import Web3 from 'web3'
import HDWalletProvider from "truffle-hdwallet-provider";
let getWeb3 = new Promise(function(resolve, reject) {
// Wait for loading completion to avoid race conditions with web3 injection timing.
window.addEventListener('load', function() {
let results
let web3 = window.web3
// Checking if Web3 has been injected by the browser (Mist/MetaMask)
if (typeof web3 !== 'undefined') {
// Use Mist/MetaMask's provider.
web3 = new Web3(web3.currentProvider)
results = {
web3: web3
}
console.log('Injected web3 detected.');
return resolve(results)
} else {
// Fallback to localhost if no web3 injection. We've configured this to
// use the development console's port by default.
// let provider = new Web3.providers.HttpProvider("https://ropsten.infura.io/your_infura_api_key")
let mnemonic = "infura mnemonic"
let provider = new HDWalletProvider(mnemonic, "https://ropsten.infura.io/your_infura_api_key")
web3 = new Web3(provider)
results = {
web3: web3
}
console.log('No web3 instance injected, using Local web3.');
return resolve(results)
}
})
})
export default getWeb3

我们开发了一个小型库来将 Truffle 与 Trezor 硬件钱包结合使用：https://github.com/rariblecom/trezor-provider
可以这样使用：
const { createProvider } = require('@rarible/trezor-provider')
module.exports = {
networks: {
ropsten: {
provider: function() {
//websocket and http urls are supported
return createProvider({ url: "{infura or other}", path: "m/44'/60'/0'/0/0", chainId: 3 })
},
network_id: 3
}
}
};
