Important note regarding Polkadot staking rewards
- In order to ensure consistent eligibility, it's best to bond more than the minimum. Typically 20 or more DOT above the minimum is enough to ensure consistent eligibility for rewards:
- Minimum to earn rewards:
- Minimum to nominate:
- If you are below the minimum to get rewards staking from your account, consider joining a Polkadot Nomination Pool and get rewards on as little as 2.25 DOT.
Earn Polkadot (DOT) rewards* by bonding assets first, and then nominating validators in Ledger Live. The validators you nominated will use your bonded assets to stake and collect rewards for you. Learn how nomination works >
Check the Polkadot wallet page to learn more.
Before you start
- Update Ledger Live through the notification banner or download the latest version.
- Open Ledger Live, connect your Ledger device to My Ledger and make sure your device is running the latest firmware version and Polkadot (DOT) app.
- Add a Polkadot (DOT) account. Learn more
Bonding your assets
To earn DOT staking rewards, you first need to bond your DOTs.
Your bonded DOTs can be unbonded at any time but please note it takes 28 days for a DOT balance to fully unbond.
- On your Polkadot account page, click on the Stake button.
- Select Bond.
- If prompted, select where you would like to receive your staking rewards:
- Available balance: Rewards are credited to your available balance.
- Bonded balance: Rewards are credited to your bonded balance for compound earning.
Note that Ledger Live doesn’t allow you to change the rewards destination later. To change the rewards destination, you can use the third-party wallet Polkadot.js. For detailed instructions, please refer to the Polkadot guide.
- Enter the amount of DOTs to bond. Then click on Continue.
Make sure to keep enough DOT in your available balance to pay transaction fees for other operations such as nominating validators, unbonding, or withdrawing assets.
- Verify and approve the bonding transaction on your Ledger device.
- Open the Polkadot app on your device after you've connected and unlocked your device.
- Press the right button to review all operation details: Staking, Controller, Value, Payee.
- Press both buttons to Approve and send the operation. Choose Reject to cancel the operation.
Once the bonding transaction is confirmed on the Polkadot network, your bonded DOT balance will appear here:
Congratulations, you've successfully bonded your DOTs.
The next step is to nominate validators.
Nominating validators
In Polkadot, staking rewards are earned by nominating validators.
Validators are private entities that are providing a service to the Polkadot network and earn DOT rewards in return. You can learn more about the roles and responsibilities of a validator here.
Every 24 hours (also called an era) a new set of validators is elected to produce blocks and add them to the Polkadot blockchain. The Polkadot network then automatically rewards elected validators for their work by minting new DOT coins.
The validators will then share a portion of this reward with DOT holders that are nominating them. This is how rewards are shared across the Polkadot network.
To nominate validators:
- In your Polkadot account, click Nominate.
- In the Nominate window, select up to 16 validators.
- Avoid nominating a validator that is oversubscribed.
Oversubscribed?
- A validator is oversubscribed when it receives too many nominations.
- In Polkadot, only the top 512 nominators of each active validator receive rewards.
- So if a validator is active but over-subscribed, you must be a part of the 512 highest bonded nominators to receive rewards. If not, you will not receive any rewards.
-
If, however, an active nominee is not over-subscribed, you will receive staking rewards normally.
- Validators take an arbitrary commission between 0% and 100% on the received rewards. The commission can change over time. Make sure to select nominators who charge less than a 100% commission otherwise you will not receive any staking rewards.
Still unsure which validators to choose? This guide can help.
-
- Avoid nominating a validator that is oversubscribed.
- Click on Continue.
- Verify and confirm the nomination operation on your Ledger device.
- Open the Polkadot app after you've connected and unlocked your device.
- Press the right button to review all operation details: Staking, Targets.
- Press both buttons to Approve and send the operation. Choose Reject to cancel the operation.
You have successfully nominated validators.
You can view the list of current nominations in the Nominations section on the Polkadot account page.
Receiving DOT staking rewards
DOT rewards are received when an active validator you've nominated claims them for you. Typically, active validators do this daily. Once claimed, rewards will be visible in the 'Latest Operations' section of your Polkadot account.
To claim rewards yourself or track pending rewards, please use the third-party wallet Polkadot.js.
Unstaking your DOT funds
In Polkadot, unstaking a bonded DOT balance is a multi-step process. Each step requires a transaction which you need to confirm on your Ledger device.
It takes 3 steps to completely unstake your DOT funds:
- Your bonded balance must first be chilled. In Ledger Live, chilling is called clearing nominations.
- Your chilled balance must then be unbonded. Unbonding takes 28 days to complete.
- Finally, your unbonded balance can be withdrawn back to your available balance.
Once your DOT has returned to your available balance, it can be freely traded or transferred to third-party accounts.
You can find a detailed breakdown of each step below.
Clearing nominations
Clearing nominations (also known as chilling your nomination) is the first step towards unstaking your DOT funds . Your DOT will remain bonded but you will stop receiving staking rewards.
- Connect your Ledger device to your computer, unlock it and open the Polkadot (DOT) app.
Your Ledger displays: Polkadot Ready. - In your Polkadot account, click on the Stake button.
- Then select Clear Nominations.
- Read the information displayed in the popup then click on Continue.
Your Ledger device displays: Please review. - Using the buttons, review the transaction on your Ledger device. If all looks good, select APPROVE and press both buttons simultaneously to sign the transaction.
Ledger Live displays: Transaction sent successfully.
You have successfully cleared/chilled all nominations and you will no longer earn staking rewards. However, you can still receive any pending rewards that have not yet been claimed.
Unbonding your assets
To make your bonded DOT available again, you now need to unbond them.
- In your Polkadot account, click Stake > Unbond.
- In the Unbond assets window, enter the amount to unbond. Then click on Continue.
Please note that the process to unbond a DOT balance takes 28 days to complete.
- Verify and confirm the unbond operation on your Ledger device.
- Open the Polkadot app after you've connected and unlocked your device.
- Press the right button to review the transaction.
- If all looks good, select APPROVE and press both buttons simultaneously to sign the transaction to unbond your DOTs.
Ledger Live displays: Unbond transaction sent successfully.
When will my DOT become available to transfer?
- The process to unbond a DOT balance takes 28 days to complete.
- Once the unbonding is complete, you'll need to create another transaction to withdraw your unbonded DOT balance back to your available balance.
- Once your DOT is withdrawn back to your available balance, it becomes available to transfer and trade freely.
Rebonding your assets
You can rebond an unbonding or unbound DOT balance at any time. These assets will be transferred from the unbonding or unbonded balance to the bonded balance. Assets you have most recently unbonded are first rebonded. DOTs in the bonded balance are locked and actively used for staking.
- In the Unbonding section, click on the Rebond button.
- In the Rebond assets window, enter the amount to rebond. Then click on Continue.
- Verify and confirm the rebond transaction on your Ledger device.
- Open the Polkadot app after you've connected and unlocked your device.
- Press the right button to review the transaction.
- If all looks good, select APPROVE and press both buttons simultaneously to sign the transaction to rebond your DOTs.
Ledger Live displays: Assets succesfully rebonded.
You have successfully rebonded your assets. Your bonded assets can be unbond at any time.
Withdrawing your unbonded assets
This is the final step for unstaking your DOT funds.
After the 28-day unbonding period, you can withdraw unbonded DOTs from your Unbonded balance to your Available balance.
- On your Polkadot account page, click Stake > Withdraw.
- After reading the information window, click on Continue.
- Verify and confirm the withdraw operation on your Ledger device.
- Open the Polkadot app after you've connected and unlocked your device.
- Press the right button to review all operation details: Staking, Num slashing span, Chain.
- Press both buttons to Approve and send the operation. Choose Reject to cancel the operation.
You have successfully withdrawn your assets from the unbonded balance. You can track this operation in the Latest Operations section on the Polkadot account page. Once the operation is confirmed, your assets will be sent back to your available balance.
