\n

Fintech developers looking to enable users to track their xPub, and end users that would like to have a view of your crypto portfolio, including a Ledger xPub key, can use the Vezgo API<\/a> to connect and track their Bitcoin xPub Address. <\/p>\n\n\n\n

What is an xPub Address?<\/h2>\n\n\n\n
\n

An xPub, or an extended address, is a type of public key representing a collection of public keys or addresses. All child public keys, which are used to view your transaction histories and receive crypto transactions, are derived from it.<\/strong><\/p>\n<\/blockquote>\n\n\n\n

Before we go deeper into xPub Address, if you are building a crypto portfolio tracker and you need an API to help gather portfolio data from various exchanges and wallets at once, try Vezgo API<\/a>. <\/p>\n\n\n\n

If you are a crypto investor looking for a portfolio tracker that uses Vezgo, have a look at our selection of crypto portfolio tracking tools that will let you view your xPub balance<\/a>.<\/p>\n\n\n\n

Now, let’s dig deeper into xPub…<\/p>\n\n\n\n

How does an xPub work?<\/h2>\n\n\n\n
\"what<\/figure>\n\n\n\n

An xPub, or extended public key, is a type of public key used to generate other public keys or addresses. In other words, an xPub address is a parent address that gives birth to many child addresses<\/strong>.<\/p>\n\n\n\n

One Parent Address & Many Children<\/h3>\n\n\n\n

On Ledger, have you noticed that whenever you need to receive some crypto funds, your crypto wallet generates a new public address different from your previous one? More like using a different bank account number for each transaction.<\/p>\n\n\n\n

Ever wondered why that happens?<\/p>\n\n\n\n

Assume Carla has 100BTC in her wallet and wants to send 30BTC to Martin. What actually happens is that all of Carla\u2019s 100BTC leave her wallet. The 30BTC that\u2019s meant for Martin goes into Martin\u2019s wallet. But Carla\u2019s balance is transferred to a new wallet address.<\/p>\n\n\n\n

This is so that Carla is protected if her initial wallet is compromised, or so Carla’s wallet address remains private. This concept is called Unspent Transactions Output (UTXO)<\/a>.<\/p>\n\n\n\n

While the idea of UTXO is great, it has some problems: <\/p>\n\n\n\n
