<p>Inspired by @NickODell answer, I created another example using nodejs that derives 5 receiving addresses and 5 change addresses.</p>

<p>You will need these two modules:
<code>npm install bitcoinjs-lib --save</code>
and
<code>npm install bip32-utils --save</code>
and <code>babel</code> for the <code>es6</code> javascript code support.</p>

<pre><code>import Bitcoin from 'bitcoinjs-lib';
import Bip32Utils from 'bip32-utils';

let hdNode = Bitcoin.HDNode.fromBase58('xpub...get.the.master.public.key.from.a.wallet.like.electrum...');

let receiving = hdNode.derive(0); // BIP32 m/0/&lt;n&gt; path (receiving addresses)
let receivingChain = new Bip32Utils.Chain(receiving);

for (var k = 0; k &lt; 5; ++k) {
    console.log(receivingChain.get());
    receivingChain.next();
}

let change = hdNode.derive(1); // BIP32 m/1/&lt;n&gt; path (change addresses)
let changeChain = new Bip32Utils.Chain(change);

for (var k = 0; k &lt; 5; ++k) {
    console.log(changeChain.get());
    changeChain.next();
}
</code></pre>

<p>Tested in electrum with a real wallet.</p>

<p>When you don't have a multiple account wallet you can use these BIP32 paths to generate addresses:</p>

<p><code>m/0/k</code>corresponds to the k'th keypair of the external chain of the HDW derived from master m.</p>

<p><code>m/1/k</code> corresponds to the k'th keypair of the internal chain of the HDW derived from master m. (internal, means change and other internal uses)</p>

<p>But when you want to use a wallet with multiple accounts, for example, one for each customer, the paths are more like this:</p>

<p><code>m/i/0/k</code> corresponds to the k'th keypair of the external chain of account number i of the HDW derived from master m.</p>

<p><code>m/i/1/k</code> corresponds to the k'th keypair of the internal chain of account number i of the HDW derived from master m.</p>

<p>This is the default wallet layout:</p>

This looks like a cool bit of code, but I can't honestly say that it answers the question (there is no mention of derivation paths).  This would probably be more suited as a comment linking to a github gist or something.

Sure, you are right. The paths are in the code but not correctly commented. edited the answer.

You can use it as follows:</p>

<pre><code>import { XPubGenerator } from 'xpub-generator';

const g = new XPubGenerator('xpub....');
g.nthReceiving(1);
g.nthChange(1);
</code></pre>

# What BIP32 derivation path does Electrum use?

(Asked by: username_0 on 2015-04-16)

Electrum 2.0 and up uses [BIP0032](https://github.com/bitcoin/bips/blob/master/bip-0032.mediawiki) internally. I want to write code that generates the same addresses. I can't find any information about this online.

What BIP32 paths does it use to generate addresses?

It uses m/0/ for receiving addresses, and m/1/ for change addresses.
Here's some example bitcoinj code to generate receiving addresses from an extended public key.
String serialized_xpub = "xpub.....";
unsigned int address_num = 4;
NetworkParameters params = MainNetParams.get();
DeterministicKey root_xpub = DeterministicKey.deserializeB58(null, serialized_xpub, params);

DeterministicKey receiving = HDKeyDerivation.deriveChildKey(root_xpub, new ChildNumber(0, false));
DeterministicKey new_address_key = HDKeyDerivation.deriveChildKey(receiving, new ChildNumber(address_num, false));
String new_address = new_address_key.toAddress().toString();
