LP Staking

On Stakbank you can stake LP tokens to the staking pool.

In general, you stake LPs to the staking pool to generate a passive income. At the end of a day (which is supposed to be at 21:00 PST), you will receive a reward in STAK which is calculated according to the APY.

Stakbank does not support generating LP tokens. Instead, you must use UNISWAP for generating STAK-ETH LP tokens.

● When you press the ‘Stake LP Tokens’ button, you’ll see a popup which includes:

○ Balance: your current LP tokens. If the inputted LP tokens is greater than the balance, Stakbank will not allow you to stake

○ Input field: allows you to input the LP tokens

○ Get STAK-ETH LP Tokens: press this button to land on UNISWAP and generate the LP tokens

○ Max: press this button to stake all your LPs

When pressing the ‘Unstake LP tokens’ button, you’ll see a popup which includes:

● Max: press this button to unstake all your LP tokens.

2. After the flow is done, Uniswap will return the LP token pair back to your Metamask wallet. Then you can go to the Stakbank system and start farming.

Formula

Calculate ROI of a pool

STAK_PER_YEAR = DISTRIBUTION_PERCENTAGE_A_DAY * BALANCE_OF_REWARD_POOL * 365

FORMULA: ROI (1y) = ( allocPoint / totalAllocPoint ) * 100 * STAK_PER_YEAR * STAK_PRICE / (slpBalance * reserveUSD / totalSupply) * 100

=> ROI (1m) = ROI(1y) / 12

=> ROI (1d) = ROI(1y) / 365

allocPoint is the weight number of each pool which is configurable

How to calculate STAK per day in the Yield

FORMULA:

STAK_PER_DAY = DISTRIBUTION_PERCENTAGE_A_DAY * BALANCE_OF_REWARD_POOL

STAK_IN_DOLLAR = STAK_PER_DAY * STAK_PRICE

STAK_PER_DAY_YIELD_$1000 = STAK_PER_DAY / STAK_IN_DOLLAR * 1000 * ROI (1y) / 365 * 100
