Extended Private Key (xprv)
wallet · hd-wallet
A BIP32 extended private key that can derive child private keys for a whole wallet branch.
An xprv contains private key material plus chain code metadata for hierarchical deterministic wallets. Anyone with an xprv can derive descendant private keys for its branch and spend associated funds.
An xprv is extremely sensitive and should not be exported casually. For monitoring, use an xpub or watch-only wallet instead of exposing private derivation material.
