<p>You can use <a href="https://github.com/mcdallas/cryptotools" rel="nofollow noreferrer">this</a> Python library.</p>

<pre><code>from btctools import Xpub

<p>I tried to use the following code:</p>

<pre><code>    DeterministicKey key = DeterministicKey.deserializeB58(null , "xpub...", MAINNET);



    DeterministicHierarchy hierarchy = new DeterministicHierarchy(key)
;
    DeterministicKey chain = hierarchy.deriveChild(key.getPath(), false, false, new ChildNumber(0, false));
    DeterministicKey index = hierarchy.deriveChild(chain.getPath(), false, false, new ChildNumber(0, false));
    SegwitAddress segwitAddress = SegwitAddress.fromHash(MAINNET, index.getPubKeyHash());
</code></pre>

<p>But it doesn't return correct address. 
Any help here</p>

# How to derive segwit addresses from an extended public key?

(Asked by: username_0 on 2018-06-11)

I tried to use the following code:

```
    DeterministicKey key = DeterministicKey.deserializeB58(null , "xpub...", MAINNET);

    DeterministicHierarchy hierarchy = new DeterministicHierarchy(key)
;
    DeterministicKey chain = hierarchy.deriveChild(key.getPath(), false, false, new ChildNumber(0, false));
    DeterministicKey index = hierarchy.deriveChild(chain.getPath(), false, false, new ChildNumber(0, false));
    SegwitAddress segwitAddress = SegwitAddress.fromHash(MAINNET, index.getPubKeyHash());

```

But it doesn't return correct address.
Any help here

Zpub's would be needed for native segwit addresses. And current bitcoinj master branch does not support Zpub, it support xpub and xpub's would always derive to
legacy addresses. Give a try to Segwit branch that may helps. Also take a look at [this](https://github.com/bitcoinj/bitcoinj/pull/1563)

You can use [this](https://github.com/mcdallas/cryptotools) Python library.

```
from btctools import Xpub

>>> extended = Xpub.decode('xpub123...')
>>> child = extended/0/0
>>> child.key.to_address('P2WPKH')
'bc1q0xedk29m3z0ja0l5xl2avclrhkd8y9z5au5wyt'

```
