Extended Public Key (xpub)
A BIP32 extended public key that derives many child public keys and addresses without revealing private keys.
- Acronym
- xpub
An xpub contains public key and chain code data for a wallet branch. It lets software generate receiving addresses and monitor transactions without holding the corresponding private keys.
An xpub cannot spend funds, but it can reveal wallet structure and link many addresses together. It should be shared only with services that need that visibility.
