They are built on the raw-transaction and wallet RPCs (`createrawtransaction`, `signrawtransaction`, `createmultisig`, `dumpprivkey`) that zcashd deprecated before the halt; Zallet replaces those with new methods that operate on PCZTs rather than raw transaction hex, and is still in beta with many zcashd methods not yet ported.

To move an existing node off zcashd, see the [migration guide to Zebra and Zallet](/guides/migration-guide-zcashd-to-zebrad-zallet).

+> Todos los pasos siguientes dependen de zcashd, que alcanzó su parada automática de fin de soporte el 18 de julio de 2026. Los siete scripts que acompañan a esta página lo controlan mediante `zcash-cli`, por lo que ninguno puede comunicarse hoy con un nodo en ejecución.
+>
+> Estos scripts no pueden portarse de forma mecánica: se basan en RPC de transacción en bruto y de monedero que zcashd dejó obsoletas, y Zallet las sustituye por métodos nuevos que operan sobre PCZT en lugar de hex de transacción en bruto.

+> Para custodia multiparte en Zcash hoy, consulta [FROST y custodia por umbral](/zcash-tech/frost-threshold-custody) y la [demostración FROST con Ywallet](/guides/frostdemo/ywallet-frost-demo). Para migrar un nodo existente fuera de zcashd, consulta la [guía de migración a Zebra y Zallet](/guides/migration-guide-zcashd-to-zebrad-zallet).
