Truffle Usage

You can easily use this within a Truffle configuration. For instance:

truffle.js

var WalletProvider = require("truffle-wallet-provider");

// Read and unlock keystore
var keystore = require('fs').readFileSync('./keystore').toString();
var pass = require('fs').readFileSync('./pass').toString();
var wallet = require('ethereumjs-wallet').fromV3(keystore, pass);

module.exports = {
  networks: {
    development: {
      host: "localhost",
      port: 8545,
      network_id: "*" // Match any network id
    },
    ropsten: {
      provider: new WalletProvider(wallet, "https://ropsten.infura.io/"),
      network_id: 3
    }
  }
};
