The following describes how to stop nominating or validating and retrieve your tokens. Please note that all networks on which you can nominate have a delayed exit period, called the unbonding period, which serves as a cooldown. You will not be able to transfer your tokens before this period has elapsed, and you will not receive any staking rewards during this period (as you are not nominating any validators).
On the Polkadot-JS Apps navigate to the "Staking" tab.
在页面左上角点击 "Account Actions"。
Here, click "Stop Nominating" or "Stop Validating" (depending on your role) on an account you're staking with and would like to free the funds for.
After you confirm this transaction, your tokens will remain bonded. This means they stay ready to be distributed among nominees or used as validator self-stake again. To actually withdraw them, you need to unbond.
To unbond the amount, click the little gear icon next to the account you want to unbond tokens for, and select "Unbond funds".
该持续时间会因您所使用的网络而异，在 Kusama 上的速度通常是 Polkadot 上速度的四倍。
Once this process is complete, you will have to issue another, final transaction: Withdraw Unbonded.
You can also check how long you have to wait in order to withdraw your stake in the Accounts page by expanding your account balance. There is a tiny icon beside the word "unbonding" that will eventually become an unlock icon once the remaning blocks get passed.
Then, you can click that icon directly to submit the withdraw transaction. Finally, your transferrable balance will increase by the amount of tokens you've just fully unbonded.
Rebonding before the end of the unbonding period
If you want to rebond your tokens before the unbonding period is over you can do this by issuing a
rebond extrinsic. This allows you to bond your tokens that are still locked without waiting until the end of the unbonding period.
In order to do this you will need to issue an extrinsic manually from Polkadot-JS Apps.
Go to the "Extrinsics" option that's located in the "Developer" dropdown in the top menu.
Select the "staking" pallet and the "rebond" extrinsic. Enter the amount of tokens that are currently locked in unbonding that you want to rebond. Then click "Submit Transaction".
Confirm the transaction in the next pop-up. Once the transaction is included in the next block your tokens will be rebonded again and you can start staking with them.
