If you are new to Bitcoin payments, terms like xPub or extended public key might sound confusing.
This guide will help you understand what an xPub is, why Blockonomics needs it, how to find xPub and receiving address for your wallet, and what are the risks of revealing your xPub.

What is an xPub?

xPub (Extended Public Key) is a special public key from your Bitcoin wallet.


Every Bitcoin wallet is made up of two kinds of keys private keys (which let you spend your Bitcoin) and public keys (which let you receive it).


It usually begins with the prefix xpub, ypub, or zpub, depending on your wallet type.


Blockonomics uses your xPub to generate a unique Bitcoin address for each order. These addresses belong to your own wallet, so all payments are received directly and instantly into it.

A single xPub (Extended Public Key) can generate multiple unique Bitcoin addresses within the same wallet.
