What is the idea behind staking?

Staking is the process of locking your Liquidity Pool tokens (LP Tokens) so that you can earn rewards. The level of reward is determined by the length of the lockup period. You can also leave your staked tokens ‘unlocked’ and still earn the basic level of rewards (this will allow you to unstake them at any point in time). In order to stake, you first need to provide liquidity for a pair of tokens (eg. BDEU and BDX).
*Please note that this locking functionality is aimed at experienced users and that once set as locked, there is no way to unlock a stake. This can then lead to a substantial loss of funds.

What is the difference between locked and unlocked staking?

You can choose between leaving your stakes unlocked (and in this case, you can unstake it at any given point in time) or lock it for a predetermined period of 1, 2, 3, 5, or 10 years. While you won’t be able to unlock it until the locking period lapses, you will enjoy higher multiple reward earnings for longer locking periods.
Staking: Stake LP tokens, earn BDX as rewards. Increase your rewards by locking up the stakes.

Can I stake any token?

You can only stake LP (liquidity provider) tokens that represent a pair of tokens in the liquidity pool. This means you will have to provide liquidity before you can participate in the stake rewards program.

How often are rewards distributed?

Rewards accumulate every minute. You can claim your rewards via the staking page.
Please note that 10% of the rewards will be paid as a fee to the protocol for ongoing operational expenses (providing liquidity, recollateralization, incentivizing members of the DAO that helped the protocol, etc).
Of the remaining funds, 10% will be available immediately upon the claim, while the rest of the funds will be released linearly over the following 9 months and could be claimed back to the wallet whenever you choose via the Vesting Schedule page.
