truffle-hdwallet-provider-xprv
Fork of https://github.com/trufflesuite/truffle-hdwallet-provider
HD Wallet-enabled Web3 provider. Use it to sign transactions for addresses derived from an extended private key.
Install
$ npm install truffle-hdwallet-provider-xprv
or
$ yarn add truffle-hdwallet-provider-xprv
Requirements
Node >= 7.6
General Usage
You can use this provider wherever a Web3 provider is needed, not just in Truffle. For Truffle-specific usage, see next section.
var HDWalletProvider = ;var xprv = "xprv9s21ZrQH143K4KqQx9Zrf1eN8EaPQVFxM2Ast8mdHn7GKiDWzNEyNdduJhWXToy8MpkGcKjxeFWd8oBSvsz4PCYamxR7TX49pSpp3bmHVAY";var provider = xprv "http://localhost:8545"; // Or, alternatively pass in a zero-based address index.var provider = xprv "http://localhost:8545" 5;
By default, the HDWalletProvider
will use the address of the first address that's generated from the xprv. If you pass in a specific index, it'll use that address instead. Currently, the HDWalletProvider
manages only one address at a time, but it can be easily upgraded to manage (i.e., "unlock") multiple addresses.
Parameters:
xprv
:string
. Extended private key which addresses are created from.provider_uri
:string
. URI of Ethereum client to send all other non-transaction-related Web3 requests.address_index
:number
, optional. If specified, will tell the provider to manage the address at the index specified. Defaults to the first address (index0
).
Truffle Usage
You can easily use this within a Truffle configuration. For instance:
truffle.js
var HDWalletProvider = ; var xprv = "xprv9s21ZrQH143K4KqQx9Zrf1eN8EaPQVFxM2Ast8mdHn7GKiDWzNEyNdduJhWXToy8MpkGcKjxeFWd8oBSvsz4PCYamxR7TX49pSpp3bmHVAY"; moduleexports = networks: development: host: "localhost" port: 8545 network_id: "*" // Match any network id ropsten: provider: xprv "https://ropsten.infura.io/" network_id: 3 ;
