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.
Currently, the xpub is available for iOS devices only. For Android users, it'll be added in future updates.
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.
