【中文标题】使用 Trezor(硬件钱包)将签名交易发送到 Ropsten 或 Truffle 开发网络【英文标题】:Send signed transactions to Ropsten or Truffle develop network with Trezor (Hardware Wallet) 【发布时间】:2018-11-08 19:28:33 【问题描述】: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。
想法是使用硬件钱包对交易进行签名,然后使用 web3js 发送原始交易
我知道我们没有余额来进行交易,可能是因为 web3js 没有使用 10 个 truffle 帐户之一,而是使用不在我本地网络中的 trezor 地址..
在 ropsten 我有一些以太币,我得到“无效地址”
有没有办法使用 web3js 将签名交易(使用 trezor)发送到松露开发网络?我的意思是,有没有办法将 trezor 地址包含到松露网络中?
这里更详细地解释了松露的情况,但问题可以概括为“有没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 我已经成功地在回调中发送了一个交易并接收了一个交易哈希,但是如果我们查询该交易,我们会发现该交易不存在.. 那么.. 这怎么可能?
我也尝试将合约部署到 Ropsten 中,现在在调用智能合约功能时我得到“无效地址”。也许签名功能是错误的?任何人都可以将 Trezor 交易签名与 web3js 集成?
你们有没有发现我们遵循的签名和发送过程有什么问题? 可能是 R、V 和 S 参数处理有问题 ..
另一件重要的事情是我使用https://github.com/ethereumjs/ethereumjs-tx 来创建原始交易

getTrezorConnect函数只是异步获取window.trezorConnect,因为对象是作为脚本注入的
<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
【问题讨论】:
【参考方案1】:好吧,经过多次尝试,我们已经成功地将使用 Trezor 签名的原始交易发送到 Ropsten、Truffle(请参阅答案底部的编辑)以及本地私有 Geth 网络,所以,代码没问题,在这些环境中集成 Trezor 没有问题
https://ropsten.etherscan.io/address/0x89e2c46b22881f747797cf67310aad1a831d50b7
这是我为了能够将签名交易发送到 Ropsten 测试网而更改的内容。
这假设您已将合约部署到 Ropsten 并且您拥有合约地址。
1) 获取您的 Trezor 帐户地址
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 地址放入原始交易的from
字段,通过获取该地址的交易计数来获取交易的nonce
。重要提示:使用 getTransactionCount 上的“pending”可选参数来获取账户的所有交易,否则您将覆盖待处理的交易。
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 中的挖掘时间将在 15 到 30 秒之间,因此如果在您的 someCallbackFunction 中使用哈希检查交易收据,您将得到 null 作为结果,因为交易处于待处理状态。
4) 为了在 ropsten 进行测试,我们使用 Infura,因此我们更改了 web3 提供程序:
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

这也适用于 Truffle!查看本期最后的cmetshttps://github.com/trufflesuite/truffle/issues/973
【讨论】:
【参考方案2】:我们开发了一个小型库以将 Truffle 与 Trezor 硬件钱包一起使用: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
;
