root-register
Register a hotkey on the root network (netuid 0).
Joins the hotkey to the root network, the TAO staking pool (netuid 0 has
no miners and no alpha; validators register here to receive root stake).
Placement is stake-based rather than burn-based: root slots are limited, so
joining a full root network evicts the member with the least stake, and a
hotkey without enough stake behind it will not hold a seat. Root
registrations are also capped per block (max_registrations_per_block)
and per interval (three times target_registrations_per_interval);
hitting either cap fails until the window passes. Use
burned_register for ordinary subnets.

Parameters
| Parameter | Type | Required | Description |
|---|---|---|---|
hotkey_ss58 | string | no | Hotkey to register on the root network; defaults to the wallet's hotkey. |
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 root-register --dry-run
btcli tx root-register -w my_coldkeyPython
import bittensor as sub
from bittensor.wallet import Wallet
wallet = Wallet(name="my_coldkey", hotkey="my_hotkey")
intent = sub.RootRegister()
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("root_register", {...}, wallet)
