# move-swap-stake (/docs/tx/move-swap-stake)

Same-subnet `move_stake` onto the destination hotkey, then
`swap_stake_limit` to the destination subnet, wrapped in
`Utility.batch_all` so both legs land or neither does. Prefer
`move_stake` (which uses `move_stake_limit`) for a single
cross-subnet move. MEV shield is on by default. The two hotkeys and
the two netuids must differ. Same-hotkey crosses are `swap_stake`;
same-subnet re-delegates are `move_stake`.

Share-pool rounding can make the post-move dest position readable as
one rao less than the amount moved. The swap therefore uses `amount - 1`
so the batch does not fail with `NotEnoughStakeToWithdraw`, and 1 rao
stays on the dest hotkey at the origin subnet. A real one-call extrinsic
still needs the chain (issue #3081). Pass `all` to take the entire
origin position.

## Parameters [#parameters]

| Parameter             | Type              | Required | Description                                                                                                                                                                                                                        |
| --------------------- | ----------------- | -------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `origin_hotkey_ss58`  | string            | yes      | Hotkey the stake moves away from.                                                                                                                                                                                                  |
| `origin_netuid`       | integer           | yes      | Subnet the stake currently sits on.                                                                                                                                                                                                |
| `dest_hotkey_ss58`    | string            | yes      | Hotkey the stake lands on.                                                                                                                                                                                                         |
| `dest_netuid`         | integer           | yes      | Subnet the stake ends up on. When it differs from the origin, the position is swapped through both subnet pools, which can incur slippage on each leg.                                                                             |
| `amount_alpha`        | number \| `"all"` | yes      | How much of the origin position to move and swap, or `all`.                                                                                                                                                                        |
| `slippage_protection` | boolean           | no       | Bound the price the swap may execute at (on by default): the call fails (`SlippageTooHigh`) instead of filling once the pool price moves more than `rate_tolerance` from the price at submission. Disable to execute at any price. |
| `rate_tolerance`      | number            | no       | Maximum price move slippage protection accepts, as a fraction (0.05 = 5%). Ignored when slippage protection is disabled.                                                                                                           |

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 move-swap-stake \
  --origin-hotkey <ss58|name> \
  --origin-netuid <int> \
  --dest-hotkey <ss58|name> \
  --dest-netuid <int> \
  --amount-alpha <amount|all> --dry-run
btcli tx move-swap-stake \
  --origin-hotkey <ss58|name> \
  --origin-netuid <int> \
  --dest-hotkey <ss58|name> \
  --dest-netuid <int> \
  --amount-alpha <amount|all> -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.MoveSwapStake(origin_hotkey_ss58="5F...origin", origin_netuid=1, dest_hotkey_ss58="5G...destination", dest_netuid=2, amount_alpha=1.0)

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](/docs/concepts/client).) Or build the intent by op name, as
an agent would:

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