clear-coldkey-swap-announcement

Cancel a pending coldkey swap announcement (after the reannouncement delay).

Withdraws this coldkey's own pending swap announcement so the swap can no longer be executed — use it if you announced to the wrong key or changed your mind. Only clearable once the current block reaches the swap's execute block plus the reannouncement delay — i.e. roughly the announcement delay (~5 days) PLUS the reannouncement delay (~1 day) after announcing — so it cannot be used to rapidly cycle announcements. Nothing moves; a fresh announce_coldkey_swap can be made afterwards. If the announcement was made by an attacker, dispute_coldkey_swap is the right call instead.

Parameters

This operation takes no parameters.

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 clear-coldkey-swap-announcement --dry-run
btcli tx clear-coldkey-swap-announcement -w my_coldkey

Python

import bittensor as bt
from bittensor.wallet import Wallet

wallet = Wallet(name="my_coldkey", hotkey="my_hotkey")
intent = bt.ClearColdkeySwapAnnouncement()

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