bittensor.core.extrinsics.unstaking#

Functions#

`__do_remove_stake_single`(subtensor, wallet, ...[, ...])	Executes an unstake call to the chain using the wallet and the amount specified.
`_check_threshold_amount`(subtensor, stake_balance)	Checks if the remaining stake balance is above the minimum required stake threshold.
`_do_unstake`(self, wallet, hotkey_ss58, amount[, ...])	Sends an unstake extrinsic to the chain.
`unstake_extrinsic`(subtensor, wallet[, hotkey_ss58, ...])	Removes stake into the wallet coldkey from the specified hotkey `uid`.
`unstake_multiple_extrinsic`(subtensor, wallet, hotkey_ss58s)	Removes stake from each `hotkey_ss58` in the list, using each amount, to a common coldkey.

Module Contents#

bittensor.core.extrinsics.unstaking.__do_remove_stake_single(subtensor, wallet, hotkey_ss58, amount, wait_for_inclusion=True, wait_for_finalization=False)#

Executes an unstake call to the chain using the wallet and the amount specified.

Parameters:

wallet (bittensor_wallet.Wallet) – Bittensor wallet object.
hotkey_ss58 (str) – Hotkey address to unstake from.
amount (bittensor.utils.balance.Balance) – Amount to unstake as Bittensor balance object.
wait_for_inclusion (bool) – If set, waits for the extrinsic to enter a block before returning true, or returns false if the extrinsic fails to enter the block within the timeout.
wait_for_finalization (bool) – If set, waits for the extrinsic to be finalized on the chain before returning true, or returns false if the extrinsic fails to be finalized within the timeout.
subtensor (bittensor.core.subtensor.Subtensor)

Returns:

Flag is true if extrinsic was finalized or uncluded in the block. If we did not wait for finalization / inclusion, the response is true.

Return type:

success (bool)

Raises:

bittensor.core.errors.StakeError – If the extrinsic fails to be finalized or included in the block.
bittensor.core.errors.NotRegisteredError – If the hotkey is not registered in any subnets.

bittensor.core.extrinsics.unstaking._check_threshold_amount(subtensor, stake_balance)#

Checks if the remaining stake balance is above the minimum required stake threshold.

Parameters:

subtensor (bittensor.core.subtensor.Subtensor) – Subtensor instance.
stake_balance (bittensor.utils.balance.Balance) – the balance to check for threshold limits.

Returns:

true if the unstaking is above the threshold or 0, or false if the unstaking is below the threshold, but not 0.

Return type:

success (bool)

bittensor.core.extrinsics.unstaking._do_unstake(self, wallet, hotkey_ss58, amount, wait_for_inclusion=True, wait_for_finalization=False)#

Sends an unstake extrinsic to the chain.

Parameters:

wallet (bittensor_wallet.Wallet) – Wallet object that can sign the extrinsic.
hotkey_ss58 (str) – Hotkey ss58 address to unstake from.
amount (bittensor.utils.balance.Balance) – Amount to unstake.
wait_for_inclusion (bool) – If true, waits for inclusion before returning.
wait_for_finalization (bool) – If true, waits for finalization before returning.
self (bittensor.core.subtensor.Subtensor)

Returns:

True if the extrinsic was successful.

Return type:

success (bool)

Raises:

StakeError – If the extrinsic failed.

bittensor.core.extrinsics.unstaking.unstake_extrinsic(subtensor, wallet, hotkey_ss58=None, amount=None, wait_for_inclusion=True, wait_for_finalization=False)#

Removes stake into the wallet coldkey from the specified hotkey uid.

Parameters:

subtensor (bittensor.core.subtensor.Subtensor) – Subtensor instance.
wallet (bittensor_wallet.Wallet) – Bittensor wallet object.
hotkey_ss58 (Optional[str]) – The ss58 address of the hotkey to unstake from. By default, the wallet hotkey is used.
amount (Union[Balance, float]) – Amount to stake as Bittensor balance, or float interpreted as Tao.
wait_for_inclusion (bool) – If set, waits for the extrinsic to enter a block before returning true, or returns false if the extrinsic fails to enter the block within the timeout.
wait_for_finalization (bool) – If set, waits for the extrinsic to be finalized on the chain before returning true, or returns false if the extrinsic fails to be finalized within the timeout.

Returns:

Flag is true if extrinsic was finalized or uncluded in the block. If we did not wait for finalization / inclusion, the response is true.

Return type:

success (bool)

bittensor.core.extrinsics.unstaking.unstake_multiple_extrinsic(subtensor, wallet, hotkey_ss58s, amounts=None, wait_for_inclusion=True, wait_for_finalization=False)#

Removes stake from each hotkey_ss58 in the list, using each amount, to a common coldkey.

Parameters:

subtensor (bittensor.core.subtensor.Subtensor) – Subtensor instance.
wallet (bittensor_wallet.Wallet) – The wallet with the coldkey to unstake to.
hotkey_ss58s (List[str]) – List of hotkeys to unstake from.
amounts (List[Union[Balance, float]]) – List of amounts to unstake. If None, unstake all.
wait_for_inclusion (bool) – If set, waits for the extrinsic to enter a block before returning true, or returns false if the extrinsic fails to enter the block within the timeout.
wait_for_finalization (bool) – If set, waits for the extrinsic to be finalized on the chain before returning true, or returns false if the extrinsic fails to be finalized within the timeout.

Returns:

Flag is true if extrinsic was finalized or included in the block. Flag is true if any wallet was unstaked. If we did not wait for finalization / inclusion, the response is true.

Return type:

success (bool)
