Getting Started

Install

$   npm i --save cryptohdwallet

Add script to your package.json file

"scripts": {
    "init-wallet": "crypto-hdwallet init"
},

Initialize with CLI Tool

Run the init command in your project directory:

$   npm run init-wallet

The cli tool will help you setup a crypto-root-keys.json file in the root directory of your project.

Usage

example:

var cryptohdwallet = require('cryptohdwallet');

// number of the address derived from root, should be lower than 2^31
var count = 0;

// you should define your coin symbol at upper case
var mainBTCAddress = cryptohdwallet.getAddress('BTC', count,'main');
var changeBTCAddress = cryptohdwallet.getAddress('BTC', count,'change');

console.log(mainBTCAddress);
// => '19rF4MDgHLcqMUWBqPEPQgZ65cz549h9CX'
console.log(changeBTCAddress);
// => '13CmhUZ27p5Z26P6ELBmTsrxUTkafxLmDT'

// ethereum has no change address, you should always use 'main' as type
var ETHAddress = cryptohdwallet.getAddress('ETH', count,'main');

console.log(ETHAddress);
// => '0xF444640DE9531335eFC535147b131343c74258d0'
