Transactions
claim-root
Claim accumulated root dividends from one or more subnets.
Pays out the signing coldkey's accrued root-stake dividends from the listed
subnets. What the payout looks like depends on the coldkey's root claim
type (see set_root_claim_type): swapped to TAO, kept as subnet alpha,
or a per-subnet mix. At most 5 subnets per call — an empty or longer list
fails with InvalidSubnetNumber. Subnets whose accrued dividends are
below the per-subnet claim threshold (default 500,000 rao; adjustable by
the subnet owner or root) are silently skipped while the transaction
still succeeds. Unclaimed dividends simply keep accruing — there is no
deadline — but each call pays out only the subnets listed.

Parameters
| Parameter | Type | Required | Description |
|---|---|---|---|
subnets | array of integer | yes | Netuids to claim accumulated root dividends from; at most 5 per call. |
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 claim-root \
--subnets <a,b,c> --dry-run
btcli tx claim-root \
--subnets <a,b,c> -w my_coldkeyPython
import bittensor as bt
from bittensor.wallet import Wallet
wallet = Wallet(name="my_coldkey", hotkey="my_hotkey")
intent = bt.ClaimRoot(subnets=[...])
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("claim_root", {...}, wallet)On-chain implementation
