increase-take

Increase the delegate take of a hotkey.

The delegate take is the fraction of staking emissions a delegate hotkey keeps for itself before distributing the rest to its nominators. This call only moves the take upward: the chain rejects values at or below the current take, values above the configured maximum, and increases made sooner than the take rate limit allows. Signed by the coldkey that owns the hotkey. Use set_take if you just want to land on an absolute value without tracking the direction yourself.

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

Parameters

Parameter	Type	Required	Description
`take`	integer \| number \| string	yes	New take: a 0..1 fraction (e.g. 0.18 for 18 percent) or the raw u16 proportion (0..65535). The chain enforces its configured take bounds.
`hotkey_ss58`	string	no	Hotkey the operation applies to.

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 increase-take \
  --take <value> --dry-run
btcli tx increase-take \
  --take <value> -w my_coldkey

Python

import bittensor as bt
from bittensor.wallet import Wallet

wallet = Wallet(name="my_coldkey", hotkey="my_hotkey")
intent = bt.IncreaseTake(take="...")

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