<p>I'm trying to convert a Segwit YPUB address I got from a Ledger Wallet to a Legacy XPUB address in order to query the transactions from the wallet. I've yet to find a reliable API that supports YPUB and I'm using Blockchain.info to fetch the information for Bitcoin.</p>

<p>While I've tried multiple methods to convert a YPUB to XPUB (getting the same addresses with every method I've found - changing the header with the network specific magic key), I don't see the balance on the resulted XPUB address. It shows 0 balance.</p>

<p>Is it possible that a converted address would display the balance of the original address?</p>

# Converted Segwit address (YPUB) to Legacy (XPUB), but balances differ

(Asked by: username_0 on 2018-06-26)

I'm trying to convert a Segwit YPUB address I got from a Ledger Wallet to a Legacy XPUB address in order to query the transactions from the wallet. I've yet to find a reliable API that supports YPUB and I'm using Blockchain.info to fetch the information for Bitcoin.

While I've tried multiple methods to convert a YPUB to XPUB (getting the same addresses with every method I've found - changing the header with the network specific magic key), I don't see the balance on the resulted XPUB address. It shows 0 balance.

Is it possible that a converted address would display the balance of the original address?

Thanks,

* You can use an explorer like [blockonomics](https://www.blockonomics.co) that supports [segwit xpubs](https://blog.blockonomics.co/a-segwit-blockexplorer-47cd516dd8c5) and also has an API
* If you want to use blockchain.info only, you need to derive the segwit addresses from the ypub and then lookup these addresses to get the balance. Here is [a script](https://gist.github.com/matthewdowney/998e6cfc750d286b3e2cca1aac7ca0ed). Converting ypub to xpub won't work because bc.info will still generate legacy P2PKH addresses from xpub, whereas it should generating segwit in P2SH addresses.
