Ethereum: How do I export an xpub from Bitcoin Core for use in BTCPayServer?

`

Replace the address you want to export XPR and “” with the path you want to save the file.

For example, if you have an address ABC123, you can drive:

`Bash

Bitcoin-Clic Getaddressinfo-XPR ABC123> XPR_ABC123.TXT

`

It prints a file containing XPR PEM format. Save this file with an extension .txt and it’s ready for use.

Step 2: XPR btcpapserver Laying **

If you want to bring XPR BTCPapserver, you need to create a new private key with the CreatenewKey command. Here is an example:

`Bash

Bitcoin-Clie CreatenewKey-Path >

`

Replace with the path you type in the XPR file and ' path you want to save the created private key.

For example, if you havePR_ABC123.TXT Fail/Road/to/XPR, you can take:

`Bash

Bitcoin-Clie CreatenewKey-Path/Road/to/XPR>/PATE/TO/TO/PRIPENE_KEY

`

It creates a new private key and safely in the system.

XPR Test with BTCPAPSERVER

When you have a private key, you can confirm the authenticity of payment with the Vardify command. Here is an example:

`Bash

Btcpapserver Varnify -Key -XPR

`

Replace with the path where you recorded the private key and" the path you type in the XPR file.

For example:

`Bash

Btcpapserver Valivie -Key/Pate/to/Provery_Key -XPR/CHACK/TO/TO/XPR

`

This creates a certification result indicating whether the payment is valid or not. If the payment is valid, BTCPASServer should show a public key that you can use in your application.

Tips and Variations

• In the system, be sure to make sure that XPR safers with methods such as encryption and protected password management.

• You can also use other methods to check your payments, for example, using the “Vardify` -Pkey”, not a new private key.

• If you need more advanced certification checks or custom signature algorithms, you may want to consider using additional libraries or tools for certain use.

I hope this article will help you successfully take XPR from Bitcoin Core and use it with BTCPaserver!
