$USDC L'APY (Annual Percentage Yield) indicates the annual percentage yield, taking into account the compounding of interest (i.e., interest generates further interest). With an APY of 10%, after one year, 1000 USDC becomes approximately 1104.71 USDC if the interest is automatically reinvested (compounding).

The actual gain is therefore approximately 104.71 USDC in one year, or 10.47% due to the effect of compound interest. If the interest were not reinvested (simple interest), the gain would be exactly 100 USDC.
