# kill-pure-proxy (/docs/tx/kill-pure-proxy)

Must be signed *by the pure proxy itself* (i.e. dispatched through it with
`proxy_for=<pure proxy>`), and the parameters must reproduce the exact
creation: spawner, type, index, plus the block height and extrinsic index
of the `create_pure_proxy` call. Irreversible — any funds left in the
account become permanently inaccessible, so empty it first.

| Signer    | Pallet | Wraps             |
| --------- | ------ | ----------------- |
| `coldkey` | Proxy  | `Proxy.kill_pure` |

## Parameters [#parameters]

| Parameter      | Type    | Required | Description                                                 |
| -------------- | ------- | -------- | ----------------------------------------------------------- |
| `spawner_ss58` | string  | yes      | Account that originally created the pure proxy.             |
| `proxy_type`   | string  | no       | Type the pure proxy was created with (must match exactly).  |
| `index`        | integer | no       | Index the pure proxy was created with (must match exactly). |
| `height`       | integer | no       | Block number of the creating create\_pure\_proxy call.      |
| `ext_index`    | integer | no       | Extrinsic index of the creating call within that block.     |

Address parameters (`--hotkey`, `--coldkey`, `--dest`, ...) accept a raw ss58
address, an address-book or proxy-book name, or a local wallet/hotkey name.

## CLI [#cli]

Preview with `--dry-run` (shows fee, effects, and policy result without
submitting), then submit:

```bash
btcli tx kill-pure-proxy \
  --spawner <ss58|name> --dry-run
btcli tx kill-pure-proxy \
  --spawner <ss58|name> -w my_coldkey
```

## Python [#python]

```python
import bittensor as sub
from bittensor.wallet import Wallet

wallet = Wallet(name="my_coldkey", hotkey="my_hotkey")
intent = sub.KillPureProxy(spawner_ss58="5F...")

async with sub.Client("finney") as client:
    plan = await client.plan(intent, wallet)   # fee, effects, policy — no submission
    result = await client.execute(intent, wallet)
    if not result.success:
        print(result.error.code, result.error.remediation)
```

Or build it by op name, as an agent would:

```python
await client.execute_tool("kill_pure_proxy", {...}, wallet)
```
