swap-coldkey-announced
Execute a previously announced coldkey swap (after the delay has passed).
Step two of the two-step migration: reveals the new coldkey and moves
everything the signing coldkey owns — balance, stake, and subnet ownership
— to it. Irreversible once included. The revealed key must hash to exactly
what announce_coldkey_swap committed to, and the call fails if the
announcement delay has not elapsed, no announcement exists, or the swap
is frozen by a dispute. After it succeeds, the old coldkey is empty; all
future operations sign with the new coldkey.

Parameters
| Parameter | Type | Required | Description |
|---|---|---|---|
new_coldkey_ss58 | string | yes | Coldkey receiving everything; must match the previously announced hash exactly. |
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 swap-coldkey-announced \
--new-coldkey <ss58|name> --dry-run
btcli tx swap-coldkey-announced \
--new-coldkey <ss58|name> -w my_coldkeyPython
import bittensor as sub
from bittensor.wallet import Wallet
wallet = Wallet(name="my_coldkey", hotkey="my_hotkey")
intent = sub.SwapColdkeyAnnounced(new_coldkey_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:
await client.execute_tool("swap_coldkey_announced", {...}, wallet)
