# z\_listunifiedreceivers - Zcash

This method decomposes a Unified Address into its component receivers. Unified Addresses (introduced with NU5) can contain a transparent receiver (`p2pkh` or `p2sh`), a Sapling receiver, and/or an Orchard receiver — all in a single encoded string. This method returns the individual receiver strings that a sender can use to direct payments to specific pools.

## Parameters

| Parameter         | Type   | Required | Description                  |
| ----------------- | ------ | -------- | ---------------------------- |
| `unified_address` | string | Yes      | Unified Address to decompose |

## Response Parameters

| Parameter | Type   | Description                                                                                      |
| --------- | ------ | ------------------------------------------------------------------------------------------------ |
| `orchard` | string | Orchard receiver as a standalone address string (present if the UA includes an Orchard receiver) |
| `sapling` | string | Sapling receiver as a `zs1...` address (present if the UA includes a Sapling receiver)           |
| `p2pkh`   | string | Transparent P2PKH receiver as a `t1...` address (present if the UA includes a P2PKH receiver)    |
| `p2sh`    | string | Transparent P2SH receiver as a `t3...` address (present if the UA includes a P2SH receiver)      |

## Use Cases

* **Send Path Selection**: Determine which pool(s) a Unified Address supports before selecting a spending strategy
* **Wallet Compatibility Detection**: Sending wallets without Orchard support extract the Sapling receiver as a fallback
* **Address Analytics**: Study Unified Address adoption patterns by receiver-type composition
* **Legacy Fallback Support**: Wallets on older networks fall back to transparent receivers when shielded support is unavailable

## Error Handling

| ---------- | --------------------- | ----------------------------------------- |
| -8         | Not a Unified Address | Input is not a valid Unified Address      |
| -32602     | Invalid params        | Address parameter is missing or malformed |
| -32603     | Internal error        | Node failed to decompose the address      |
