Annual Percentage Yield
Orca Protocol offers: Automatic staking and compounding features and the highest Fixed APY in the market at 916,474% for the first 12 months. APY stands for Annual Percentage Yield. This measures the real rate of return on your principal amount by taking into account the effect of compounding interest. In the case of the Orca Protocol, your $OP tokens represent your principal, and the compound interest is added periodically on every Rebase event (Every 15 minutes), otherwise known as an 'Epoch'.
Your new principal amount is your then-current Orca Protocol Token amount, plus your new rebase token amount. This total amount is what gets calculated for your next rebase rewards.

EXAMPLE 1: If you started with a balance of only 1 $OP on day 1, after a year, your balance will have grown to 9164.74 $OP.
