What is an Xpub key?
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.
