reset-axon

Reset (stop serving) this hotkey's axon endpoint on a subnet.

Republishes the axon record as a placeholder (ip 0, port 1, protocol 4) so validators stop routing traffic to the old address; the storage entry is not removed. Signed by the hotkey. Use this when taking a miner offline or before moving it, then publish the new address with serve_axon when it is back up.

Signer	Origin	Pallet	Wraps
`hotkey`	signed account (pallet role may apply)	SubtensorModule	`SubtensorModule.serve_axon`

Parameters

Parameter	Type	Required	Description
`netuid`	integer	yes	Subnet whose published axon endpoint to clear.

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 reset-axon \
  --netuid <int> --dry-run
btcli tx reset-axon \
  --netuid <int> -w my_coldkey

Python

import bittensor as bt
from bittensor.wallet import Wallet

wallet = Wallet(name="my_coldkey", hotkey="my_hotkey")
intent = bt.ResetAxon(netuid=1)

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("reset_axon", {...}, wallet)
