# decrease-take (/docs/tx/decrease-take)

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 downward — the chain rejects values at or above the
current take — and unlike increases it is not rate limited, so lowering
your take is always available. Signed by the coldkey that owns the hotkey.
Use `set_take` to land on an absolute value without tracking direction.

## Parameters [#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 [#cli]

Preview with `--dry-run` (shows fee, effects, and policy result without
submitting), then submit:

```bash
btcli tx decrease-take \
  --take <value> --dry-run
btcli tx decrease-take \
  --take <value> -w my_coldkey
```

## Python [#python]

```python
import bittensor as bt
from bittensor.wallet import Wallet

wallet = Wallet(name="my_coldkey", hotkey="my_hotkey")
intent = bt.DecreaseTake(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](/docs/concepts/client).) Or build the intent by op name, as
an agent would:

```python
result = sub.execute_tool("decrease_take", {...}, wallet)
```

## On-chain implementation [#on-chain-implementation]

`SubtensorModule.decrease_take` — [`pallets/subtensor/src/macros/dispatches.rs#L492`](/code/pallets/subtensor/src/macros/dispatches.rs#L490-L498):

```rust
#[pallet::call_index(65)]
#[pallet::weight((<T as crate::pallet::Config>::WeightInfo::decrease_take(), DispatchClass::Normal, Pays::Yes))]
pub fn decrease_take(
    origin: OriginFor<T>,
    hotkey: T::AccountId,
    take: PerU16,
) -> DispatchResult {
    Self::do_decrease_take(origin, hotkey, take)
}
