Enum OvkPolicy

pub enum OvkPolicy {
    Sender,
    Custom {
        sapling: OutgoingViewingKey,
        orchard: OutgoingViewingKey,
    },
    Discard,
}

Describes a policy for which outgoing viewing key should be able to decrypt transaction outputs.

For details on what transaction information is visible to the holder of an outgoing viewing key, refer to ZIP 310.

Variants

Sender

Use the outgoing viewing key from the sender’s UnifiedFullViewingKey.

Transaction outputs will be decryptable by the sender, in addition to the recipients.

Custom

Use custom outgoing viewing keys. These might for instance be derived from a different seed than the wallet’s spending keys.

Transaction outputs will be decryptable by the recipients, and whoever controls the provided outgoing viewing keys.

Fields

sapling: OutgoingViewingKey

orchard: OutgoingViewingKey

Available on crate feature orchard only.

Discard

Use no outgoing viewing keys. Transaction outputs will be decryptable by their recipients, but not by the sender.
