用Trezor (硬件钱包)将已签署的交易发送到Ropsten或Trezor开发网络

Question

我试图将web3js和Trezor集成到松露开发网络中，或者使用ropsten测试网络。

其想法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。

我明白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，而是使用不在我的本地网络中的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“是否有办法将硬件钱包纳入松露开发网络？”：https://github.com/trufflesuite/truffle/issues/973。

使用ropsten，我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？

我也尝试过将一个契约部署到Ropsten中，现在我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？

，你们看到我们所遵循的签名和发送过程中有什么问题吗？，可能在R，V和S参数的处理上有什么问题吗？

另一件重要的事情是，使用https://github.com/ethereumjs/ethereumjs-tx来创建原始事务

getTrezorConnect函数只是异步地获取window.trezorConnect，因为对象被注入为脚本

<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

Answer 1

经过多次尝试，我们成功地将一个与Trezor签署的原始事务发送到Ropsten、Truffle (请参阅答案底部的编辑)以及本地私有Geth网络，因此，代码没有问题，在这些环境中的Trezor集成也没有问题。

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
        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，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;

       });

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，正确的处理方法是将trezor响应的值转换为十六进制：

// 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() {
        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使用Trezor硬件钱包：https://github.com/rarible/trezor-provider

它可以这样使用：

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
        }
    }
};
