The master key fingerprint (first 4 bytes of the master public key hash). Used to identify which master key this derivation belongs to in a multisig setup.
The full BIP32 derivation path from the master key. Example: "m/84'/1'/0'/0/5" for a specific address in a BIP84 wallet
The public key that corresponds to this derivation path
BIP32 derivation information for a specific public key in a multisig setup. This provides the wallet with the necessary information to derive the correct private key for signing and to validate signatures from other cosigners.
