# set-reject-staking-hotkey-growth (/docs/tx/set-reject-staking-hotkey-growth)

Off by default. Incoming transfers can still use hotkeys already listed or
owned by the receiver. A subnet hotkey swap renames an existing entry when
possible; otherwise the receiver's stake stays on the old hotkey. The flag
follows a coldkey swap and does not move funds. The coldkey's own staking
actions remain subject to the overall 256-entry cap.

| Signer    | Origin                                 | Pallet          | Wraps                                                                                                              |

| `coldkey` | signed account (pallet role may apply) | SubtensorModule | [`SubtensorModule.set_reject_staking_hotkey_growth`](/code/pallets/subtensor/src/macros/dispatches.rs#L2793-L2811) |

## Parameters [#parameters]

| Parameter | Type    | Required | Description                                                                                  |
| --------- | ------- | -------- | -------------------------------------------------------------------------------------------- |
| `enabled` | boolean | yes      | True to refuse third-party staking-list growth; false to allow it up to the third-party cap. |

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 set-reject-staking-hotkey-growth \
  --enabled/--no-enabled --dry-run
btcli tx set-reject-staking-hotkey-growth \
  --enabled/--no-enabled -w my_coldkey
```

## Python [#python]

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

wallet = Wallet(name="my_coldkey", hotkey="my_hotkey")
intent = bt.SetRejectStakingHotkeyGrowth(enabled=True)

sub = bt.Subtensor()
plan = sub.plan(intent, wallet)   # fee, effects, policy — no submission
result = sub.execute(intent, wallet)
if not result.success:
    print(result.error.code, result.error.remediation)
```

(`bt.Subtensor` is also the async client — `async with bt.Subtensor() as client:`
— see [The client](/docs/concepts/client).) Or build the intent by op name, as
an agent would:

```python
result = sub.execute_tool("set_reject_staking_hotkey_growth", {...}, wallet)
```

    });
    Self::deposit_event(Event::RejectStakingHotkeyGrowthUpdated { coldkey, enabled });
    Ok(())
