Live demo shows a FROST-signed Zcash transaction posted to ZECpages: a prebuilt transaction plan JSON from a view-only wallet is hashed, a coordinator distributes the hash plus a Zcash-specific randomizer, and two participants produce commitments and signature shares that the coordinator combines into a final signature. The setup is a 2-of-3 threshold key share; no full secret ever exists, the raw signed tx is written out and broadcast, producing a transaction ID.
