A versioned extended public key format used by some wallets to indicate a specific script type (e.g., P2WPKH-in-P2SH).
Some wallets encode the script type in the extended key prefix (ypub/zpub/vpub). While not part of the original BIP32 standard, it helps wallets infer address formats.
"Importing a ypub into a compatible wallet auto-selects nested SegWit addresses."
All terms and definitions may update as the Cryptionary improves.
