APR Calculation

1. YISK/ETH LP ->

• yiskHelper -> getStakingPoolAPR(poolAddress, yiskAddress, lpToken) + (boost percent from APR) OR
• (RPS* 31536000*tokenPriceInUSD/totalValueLiquidity)*100

2. yiskUSD mint pool -> annualReward = rewardRateInDollar * 31,556,926(secondsPerYear) APR = (annualReward / totalStaked) * 100
3. Earn Revenue APR = (Total Protocol Revenue / Total Staked in Dollar) * 365 / Reward Distribution Period * 100%
4. yiskUSD/USDT LP

• (RPS* 31536000*tokenPriceInUSD/totalValueLiquidity)*100
