remove-stake-limit

Unstake alpha with a limit price (slippage protection).

Same as remove_stake except the alpha-to-TAO swap only executes while the pool price stays within the limit. With allow_partial it unstakes what it can within the limit and leaves the rest staked; without it the whole call fails once the limit would be breached. Pass all to target the entire position (the build fails if nothing is staked there). Like remove_stake, a partial unstake must leave a remainder worth at least 0.002 TAO at the simulated pool price (AmountTooLow). Prefer this over plain remove_stake when exiting large positions.

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

Parameters

Parameter	Type	Required	Description
`hotkey_ss58`	string	yes	Hotkey the stake is held on (the validator backing the position).
`netuid`	integer	yes	Subnet the stake lives on (netuid 0 is the root network).
`amount_alpha`	number \| `"all"`	yes	How much to unstake from this position, or `all`.
`limit_price_rao`	integer	yes	Worst pool price you will accept for the swap. The call fails (or fills partially when allow-partial is set) instead of executing beyond this price.
`allow_partial`	boolean	no	Execute whatever portion fits within the limit price and drop the remainder, instead of failing the whole call when the limit would be breached.

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 remove-stake-limit \
  --hotkey <ss58|name> \
  --netuid <int> \
  --amount-alpha <amount|all> \
  --limit-price-rao <int> --dry-run
btcli tx remove-stake-limit \
  --hotkey <ss58|name> \
  --netuid <int> \
  --amount-alpha <amount|all> \
  --limit-price-rao <int> -w my_coldkey

Python

import bittensor as bt
from bittensor.wallet import Wallet

wallet = Wallet(name="my_coldkey", hotkey="my_hotkey")
intent = bt.RemoveStakeLimit(hotkey_ss58="5F...", netuid=1, amount_alpha=1.0, limit_price_rao=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.) Or build the intent by op name, as an agent would:

result = sub.execute_tool("remove_stake_limit", {...}, wallet)
