Platform Rewards: Current vs Projected APR
When staking Curve LP tokens on the platform, APR numbers are displayed on each pool. This page explains each number in a bit more detail.
This is the -current- net yield percentage you will get on your collateral when you are in the pool. All fees are already subtracted from this number. I.e. if you have 100k in a pool with 10% current APR, you'll be receiving 10k USD worth of rewards per year. This yield is based on all the currently active harvests which have already been called and are currently being streaming to active participants in the pool over a 7 day period from the moment a harvest was called. When you join the pool, you will instantly receive this yield per block.
This is the yield percentage that is currently being generated by the pool, based on the current TVL, current Curve Gauge boost that is active on that pool and rewards priced in USD. If all parameters stay exactly the same for a few weeks (TVL, CRV boost, CRV price, CVX price, potential 3rd party incentives), this will eventually turn into the current APR. As that scenario is very unlikely to happen, projected APR should be taken with a grain of salt. Similarly, all fees are already abstracted from this number.
