An XPUB (Extended Public Key) is a type of key derived from a master public key (MPK). It allows for the generation of multiple public keys, which are used to receive cryptocurrencies, without compromising the security of the master key.
It's a way to generate a sequence of public keys from a single master key, making it easier to manage and track transactions and balances across different addresses within the same wallet.
Here’s how to get your XPUB key in Tangem Wallet:

- Open the Tangem Wallet app and select a token.
- On the Token page, tap the three dots in the upper-right corner and tap Generate XPUB.
- An Xpub key will be generated as a series of alphanumeric characters. You can save it on your smartphone as a .txt file or share it via message/email.
