# validateaddress - Zcash

This method validates a **transparent** Zcash address and returns metadata: whether the address is well-formed, whether it's P2PKH (`t1`) or P2SH (`t3`), and the raw script hash. For shielded and unified addresses, use `z_validateaddress` instead.

## Parameters

| Parameter | Type   | Required | Description                           |
| --------- | ------ | -------- | ------------------------------------- |
| `address` | string | Yes      | Transparent Zcash address to validate |

    "id": "getblock.io",
    "result": {
        "isvalid": true,
        "address": "t1c74RiTicVSKthLmn2c4WFLJdLDs5sQ4X6",
        "scriptPubKey": "76a914c74RiTicVSKthLmn2c4WFLJdLDs5sQ4X688ac",
        "isscript": false
    }
}
```

## Response Parameters

| Parameter      | Type    | Description                                                         |
| -------------- | ------- | ------------------------------------------------------------------- |
| `isvalid`      | boolean | `true` if the address is well-formed                                |
| `address`      | string  | The validated address                                               |
| `scriptPubKey` | string  | Hex-encoded scriptPubKey for this address                           |
| `isscript`     | boolean | `true` if the address is a P2SH (t3) address, `false` if P2PKH (t1) |

## Use Cases

* **Address Input Validation**: Validate user-supplied addresses in wallet UIs before allowing send
* **Address Type Detection**: Distinguish P2PKH from P2SH addresses to select the correct signing path
* **Explorer Search Sanity**: Verify search input is a valid address before running expensive queries

## Error Handling

| Error Code | Message        | Description                               |
| ---------- | -------------- | ----------------------------------------- |
| -32602     | Invalid params | Address parameter is missing or malformed |
| -32603     | Internal error | Node failed to validate the address       |
