Advanced tools
This is a fork of https://github.com/hussy-io/truffle-ledger-provider that actually works. Now works with web3 1.0 and truffle 5! Probably won't work for older web3 versions, but commit https://github.com/deconet/truffle-ledger-provider/commit/b184bcb55dfaf4bf372490af5268f31190d4b136 may work with older web3 versions.
Ledger Wallet-enabled Web3 provider. Use it to sign transactions with Ledger Nano S or Ledger Blue.
$ npm i truffle-ledger-provider -S
You can use this provider wherever a Web3 provider is needed, not just in Truffle. For Truffle-specific usage, see next section.
Before using Ledger Wallet-enabled Web3 provider, you must change your Ledger App configuration as follows:
const LedgerWalletProvider = require('truffle-ledger-provider');
const ledgerOptions = {
networkId: 1, // mainnet
path: "44'/60'/0'/0", // ledger default derivation path
askConfirm: false,
accountsLength: 1,
accountsOffset: 0,
};
const provider = new LedgerWalletProvider(ledgerOptions, 'http://localhost:8545');
network
: number
. Ethereum network ID. 1-mainnet, 3-ropsten, etc.path
: string
. HD derivation path.askConfirm
: boolean
. If true, deployment of each contract must be confirmed.accountsLength
: number
. Number of accounts to derivate.accountsOffset
: number
. Offset index to use to start derivating the accounts.You can easily use this within a Truffle configuration. For instance:
truffle.js
const LedgerWalletProvider = require('truffle-ledger-provider');
const INFURA_APIKEY = '...'; // set your Infura API key
const ledgerOptions = {}; // use default options
module.exports = {
networks: {
development: {
host: 'localhost',
port: 8545,
network_id: '*', // Match any network id
},
ropsten: {
provider: new LedgerWalletProvider(ledgerOptions, `https://ropsten.infura.io/${INFURA_APIKEY}`),
network_id: 3,
gas: 4600000,
},
},
};
