SignerView

zcash_client_backend::data_api::wallet

Enum SignerView 

Source 
pub enum SignerView {
    Full,
    Compact,
}
Available on crate feature pczt only.
Expand description

Selects the view produced by redact_pczt_for_signer, according to the capabilities of the receiving Signer.

Variants§

§

Full

The conservative signer view, for general-purpose Signers including deployed hardware signers (e.g. the Keystone ordinary send flow), which this view is validated against in the field.

It removes wallet metadata, Orchard-protocol and Sapling spend witnesses, and dummy signing keys (a defensive no-op for IO-finalized PCZTs, whose dummy keys were consumed by the IO Finalizer; per the PCZT specification, Signers MUST reject PCZTs that contain them). It retains proofs, binding-signature keys, and anchors, and performs no field compaction, so the view of a v5 transaction remains representable in the v1 PCZT encoding (which pczt::Pczt::serialize selects for it).

§

Compact

The compact signer view, for receivers that support the v2 PCZT encoding and can restore compacted fields with pczt::Pczt::resolve_fields.

In addition to the Full redactions — except that Sapling spend witnesses are retained so that the Signer may verify nullifiers — this clears zk-proofs and binding-signature keys, compacts resolvable Orchard-protocol fields, and removes v6 shielded anchors (v5 anchors are retained because signatures commit to them).
