Staking FAQ

B21 Earn is a feature for the users to Stake (or Unstake) their entire Crypto portfolio with a Single click and earn weekly rewards.

Staking is an activity where a user locks or holds his funds in a crypto wallet to participate in maintaining the operations of a proof-of-stake (PoS)-based blockchain system. You may think of staking as an alternative to mining.

As of now you can earn staking rewards on the following assets:

Bitcoin, Ethereum, EOS, Litecoin, Tether(USDT), Bitcoin Cash, Dash, BAT, LINK 

No. Eligible users can earn staking rewards on any eligible assets they hold on B21, regardless of where they purchase it.

Although investing in cryptos does come with an element of risk involved, there is no risk of staking your tokens. 

Minimum amount required for staking is $1 worth of crypto tokens. There is no maximum limit.

Staking is available for all the 82 countries B21 is live in. Check the list here. 

The account must be KYC verified. 

Refer to our Youtube channel for the video guide on how to stake.

Staking is done only on business days/hours (PST). It takes 4-8 hours 

You need to stake minimum 7 days to be eligible to get the staking rewards.

Each token gives a different APY (Annual Percentage Yield). You can check the staking dashboard to know about the APY for each token before you stake. 

US customers will receive the staking rewards in the same asset they staked.. Non-US customer will receive the staking rewards in B21 Tokens

You begin to earn rewards as soon your staking process is complete. Rewards are calculated every Friday and distributed every Tuesday. That means that if you stake tokens in the middle of the week, you will still earn prorated rewards on those assets through the accrual period on Friday. However, if you transfer your coins on Friday, Saturday, or Sunday, then in that case your first reward payment will be the following Monday.

The interest rates change on a weekly basis depending on the market conditions. Reward calculation schedule is as follows:


Reward accrual period: Friday 05:00:00 UTC to Friday 04:59:59 UTC.

Reward calculation price snapshot: Friday 05:00:00 UTC

Reward payment day: Tuesday, no set time. (user notified every week by mail) 

For US users – Yes, rewards earned on all coins in the wallet are compounded and you begin to earn rewards as soon as any funds are credited to your B21 wallet.

For Non-US users – Since the rewards are in $B21 tokens, they are not compounded.

Your staking will be in process till the staking is completed on the next business day. Till that time tokens are unavailable for unstake 

For US customers, rewards received in KIND will be automatically restaked . Rewards received in B21 tokens are not staked automatically.

Yes, rewards will be added to your portfolio balance every Tuesday.

Click on the “Trophy” Icon in your app and you will see your staked tokens..

No, you will have to unstake the tokens in order to use them.

You can unstake your tokens anytime after the staking process is completed

Please note that you might not be able to unstake until the staking process is complete. In case if you are consistently facing an issue, please reach out to [email protected]
