Transactions

terminate-lease

Terminate an ended lease and take subnet ownership (beneficiary only).

Ends the lease and transfers full subnet ownership to the beneficiary: contributor dividends stop and the subnet becomes an ordinary owned subnet. Only the lease's beneficiary can call it, and only after the lease's end block has passed — earlier attempts fail, and perpetual leases (no end block) can never be terminated this way. Check the lease's end block with the lease read before calling.

Signer	Origin	Pallet	Wraps
`coldkey`	signed account (pallet role may apply)	SubtensorModule	`SubtensorModule.terminate_lease`

Parameters

Parameter	Type	Required	Description
`lease_id`	integer	yes	Lease to terminate (see the leases read).
`hotkey_ss58`	string	no	Beneficiary hotkey recorded as the subnet's owner hotkey; 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 terminate-lease \
  --lease-id <int> --dry-run
btcli tx terminate-lease \
  --lease-id <int> -w my_coldkey

Python

import bittensor as bt
from bittensor.wallet import Wallet

wallet = Wallet(name="my_coldkey", hotkey="my_hotkey")
intent = bt.TerminateLease(lease_id=0)

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

On-chain implementation

SubtensorModule.terminate_lease — pallets/subtensor/src/macros/dispatches.rs#L1696:

#[pallet::call_index(111)]
#[pallet::weight(<T as crate::pallet::Config>::WeightInfo::terminate_lease(T::MaxContributors::get()))]
pub fn terminate_lease(
    origin: OriginFor<T>,
    lease_id: LeaseId,
    hotkey: T::AccountId,
) -> DispatchResultWithPostInfo {
    Self::do_terminate_lease(origin, lease_id, hotkey)
}

Delegates to do_terminate_lease.
