我们正在尝试将web3js与Trezor集成到松露开发网络中,或者使用ropsten测试网络。
其思想是使用硬件钱包对事务进行签名,然后使用web3js发送原始事务。
我们得到的是,我们没有馀额来进行交易,可能是因为web3js没有使用10个松露帐户中的一个,而是使用不在我本地网络中的trezor地址。
我有一些以太,我得到了“无效地址”
是否有方法使用web3js将签名的事务(与trezor一起)发送到松露开发网络?我是说,有没有办法把trezor地址包含到松露网络中?
松露的情况在这里有更详细的解释,但问题可以概括为“有办法将硬件钱包纳入松露开发网络吗?”:https://github.com/trufflesuite/truffle/issues/973。
使用ropsten,我们成功地发送了一个事务,并在回调中接收了一个事务散列,但是如果我们查询该事务,就会得到事务不存在。所以..。那件事怎么可能?
我们也尝试过将一个契约部署到Ropsten中,现在我们在调用智能契约函数时得到了“无效地址”。也许签名函数是错的?任何人都可以将Trezor事务与web3js进行集成吗?
你们认为我们所遵循的签约和发送过程中有什么问题吗?也许R,V和S的参数处理有什么问题..。
另一件重要的事情是,我们使用https://github.com/ethereumjs/ethereumjs-tx来创建原始事务。

经过多次尝试,我们成功地将一份与Trezor签署的原始交易发送给Ropsten,基于Tudor Constantin help:
https://ropsten.etherscan.io/address/0x89e2c46b22881f747797cf67310aad1a831d50b7
为了能够将已签名的事务发送到Ropsten testnet,我对这些内容进行了更改。
这假设您已经将您的合同部署到了Ropsten中,并且您有了合同地址。
1)获取你的Trezor帐户的地址
getTrezorAddress = async() => {
let trezor= await this.getTrezor();
// spend one change output
var 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,通过获取该地址的事务计数来获取事务的nonce。重要:使用getTransactionCount上的" pending“可选参数获取帐户的所有事务,否则您将过度处理挂起的事务。
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;
});
var 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,正确的处理方法是取trezor响应的值,并将其转换为十六进制:
// 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:在ropsten中的挖掘时间将在15到30秒之间,因此如果在someCallbackFunction中使用哈希检查事务收据,结果将获得null,因为事务处于挂起状态。
4)为了在ropsten上测试它,我们使用了呋喃,因此我们更改了web3提供者:
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() {
var results
var 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.
// var provider = new Web3.providers.HttpProvider("https://ropsten.infura.io/your_infura_api_key")
var mnemonic = "infura mnemonic"
var 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这也适用于特弗莱!检查这个问题的最后评论,https://github.com/trufflesuite/truffle/issues/973

你有很多问题要问。最好一次只提一个问题,这样你就有更多的机会得到答案。
让我谈谈最重要的问题。
Q1。是否有办法将硬件钱包纳入松露开发网络?
是的,通过使用truffle console和配置它连接到testrpc。使用testrpc,您可以拥有您想要的任何帐户(编辑:这不是真的-这些帐户实际上是私钥,使用HW钱包是不可用的),方法是启动它如下:
testrpc --account="0x8414315fe005b8f294020dfc61cfd13749fbc045b0c6abc31fbd1ee3f4ff3b41, 10000000000000000000" --account="0x566a9022cd3f0dfcc3dff657a6c578897d4b0300e335fa569a082b637e6bb273, 70000000000000000000" --account="0x90b4e47ca43b66fab5dbebfee464087b51923f73f649701ca485da313574fd5b, 80000000000000000000" --account="0x5d47b245c405d706fecbc5eb213819d20a2168ad696b352644ad0ffc87aef18e, 90000000000000000000"地址是你的trezor地址。
或者,您可以从trezor的种子开始(我不建议这样做,除非您确信trezor在实时网络中使用):
testrpc -m 'candy maple cake sugar pudding cream honey rich smooth crumble sweet treat'Q2:你们认为我们所遵循的签名和发送过程有什么问题吗?
我设法用Ledger硬件钱包编程地签署了eth交易。我用于签名事务的总帐 js库还返回V、R和S参数。我假设它们的格式与Trezor的库返回的格式相同,但我不能肯定。总之,这就是我如何使用V,R,S来创建有效的事务:
console.log('Please sign transaction on device...');
//the signature is an object with keys v,r and s
const signature = await eth_utils.ledger.signTransaction_async(argv['derivation_path'], tx.serialize().toString('hex'));
//"hexify" the keys
Object.keys(signature).map( (key, index) => {
signature[key] = '0x'+signature[key];
});
//tx_raw is a js object that contains all the tx params, the one that was signed on the hw device
//(equivalent of your tx from your sendTransaction() function)
const tx_obj = { ...tx_raw, ...signature};
//re-create the Transaction using ethereumjs-tx
const signed_tx = new Transaction( tx_obj );
//signed_tx_hex needs to be broadcasted
const signed_tx_hex = '0x'+signed_tx.serialize().toString('hex');就是这样。
