Transactions

set-reject-staking-hotkey-growth

Refuse new staking hotkeys introduced by other accounts.

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`

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

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

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

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.) Or build the intent by op name, as an agent would:

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