xPub, or extended public key, is a key feature used in cryptocurrency wallets. It allows users to generate multiple public addresses from a single key. This is particularly useful for managing funds and tracking transactions without exposing the private key.With an xPub, an individual can create new addresses for each transaction, enhancing privacy and security. When someone sends funds to one of these addresses, the xPub allows the wallet to recognize and display the funds without needing to know the specific address used.This feature is especially beneficial for business applications or those who receive frequent transactions. It streamlines the process of managing incoming payments while maintaining the user’s anonymity.However, care must be taken when sharing an xPub. While it does not give control over the funds, others can view transaction history associated with that key, potentially compromising privacy. Thus, users should share their xPub only when necessary and with trusted parties.
