# deriveaddresses - Bitcoin

This method derives one or more addresses corresponding to an output descriptor. Descriptors provide a way to express what scripts and keys are used in a wallet.

### Parameters

| Parameter  | Type         | Required | Description                                                                            |
| ---------- | ------------ | -------- | -------------------------------------------------------------------------------------- |
| descriptor | string       | Yes      | The output descriptor.                                                                 |
| range      | number/array | No       | If a ranged descriptor, the range to derive. Can be an integer or \[begin, end] array. |

    "id": "getblock.io",
    "result": [
        "bc1qcr8te4kr609gcawutmrza0j4xv80jy8z306fyu",
        "bc1qnjg0jd8228aq7uj72e4k5l95vjzp9ymcflfz5t",

}
```

### Response Parameters

| Field  | Type  | Description                         |
| ------ | ----- | ----------------------------------- |
| result | array | Array of derived Bitcoin addresses. |

### Use Case

The `deriveaddresses` method is essential for:

* Generating addresses from HD wallet descriptors
* Verifying address derivation paths
* Building watch-only wallets
* Implementing address gap limit scanning
* Supporting BIP32/BIP44/BIP84 address derivation
* Creating address generation tools

### Error Handling

| Status Code | Error Message      | Cause                                       |
| ----------- | ------------------ | ------------------------------------------- |
| 403         | Forbidden          | Missing or invalid ACCESS-TOKEN.            |
| -5          | Invalid descriptor | The descriptor syntax is incorrect.         |
| -8          | Range not provided | Ranged descriptor requires range parameter. |

### Integration Notes

The `deriveaddresses` method helps developers:

* Build HD wallet implementations
* Generate receiving addresses
* Implement address discovery algorithms
* Support multiple address types (legacy, SegWit, Taproot)
* Create backup verification tools
