Export XPUB

I. Introduction

• In UTXO-based cryptocurrencies like Bitcoin, change addresses are used to send back the excess amount beyond the intended recipient's address. The XPUB, which is the extended public key of your hardware wallet, is used to generate all the public addresses, including both the receiving addresses and change addresses, without exposing the private keys.

• Exporting the XPUB gives you a comprehensive view of your wallet's transaction history, including all the receiving addresses and change addresses used in transactions. This can be useful for auditing transactions for tax purposes or keeping track of your wallet activity.

• The XPUB can serve various purposes, such as auditing transactions for tax purposes or monitoring your wallet activity.

• Protect your privacy and be cautious when sharing your XPUB key. Anyone with it can monitor your wallet activity, both past and future. Keep your private keys safe and only share your XPUB key with trusted parties.
