# increase-take (/docs/tx/increase-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 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.

## 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 increase-take \
  --take <value> --dry-run
btcli tx increase-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.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](/docs/concepts/client).) Or build the intent by op name, as
an agent would:

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

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

`SubtensorModule.increase_take` — [`pallets/subtensor/src/macros/dispatches.rs#L525`](/code/pallets/subtensor/src/macros/dispatches.rs#L523-L531):

```rust
#[pallet::call_index(66)]
#[pallet::weight((<T as crate::pallet::Config>::WeightInfo::increase_take(), DispatchClass::Normal, Pays::Yes))]
pub fn increase_take(
    origin: OriginFor<T>,
    hotkey: T::AccountId,
    take: PerU16,
) -> DispatchResult {
    Self::do_increase_take(origin, hotkey, take)
}
