We address HWI with the `fingerprint` and ask for the first 1000 WPKH (native Segwit) addresses. In return, we receive two descriptors for the key pool: one for receiving addresses and one for change addresses. We address HWI with the `fingerprint` and ask for the first 1000 addresses. The WPKH (native Segwit) address type is used as a default. In return, we receive two descriptors for the key pool: one for receiving addresses and one for change addresses.
> :book: ***What is a key pool?*** A key pool is a group of pregenerated keys. Modern HD wallets create key pools by continuing to determine new hierarchical addresses based on the original seed. The idea of key pools was originally implemented to ease the backup requirements of wallets. This allowed a user to generate a keypool and then backup the wallet immediately, rather than requiring backups after every new address was created. The concept has also proven very useful in the modern day since it allows the importing of a whole set of future addresses from one device to another. > :book: ***What is a key pool?*** A key pool is a group of pregenerated keys.
