set-gamma-deposit-spender

Set who may spend your gamma deposit.

Takes effect at once; a deposit opened by a move inherits it. Set exactly one of spender_ss58, service_hotkey_ss58 or default_spender.

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

Parameters

Parameter	Type	Required	Description
`netuid`	integer	yes	Subnet of the deposit.
`hotkey_ss58`	string	yes	Hotkey of the deposit.
`spender_ss58`	string	no	The account that spends the deposit.
`service_hotkey_ss58`	string	no	Hotkey of a service published on the subnet, instead of a spender. The deposit names the spender the service publishes.
`default_spender`	boolean	no	Name the default spender: the spender of the subnet owner's service, otherwise the subnet owner, or its lease's beneficiary while a lease owns the subnet.

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 set-gamma-deposit-spender \
  --netuid <int> \
  --hotkey <ss58|name> \
  --spender <ss58|name> --dry-run
btcli tx set-gamma-deposit-spender \
  --netuid <int> \
  --hotkey <ss58|name> \
  --spender <ss58|name> -w my_coldkey

Python

import bittensor as bt
from bittensor.wallet import Wallet

wallet = Wallet(name="my_coldkey", hotkey="my_hotkey")
intent = bt.SetGammaDepositSpender(netuid=1, hotkey_ss58="5F...", spender_ss58="5F...")

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