Answer: The APY (Annual Percentage Yield) of JustLend USDD supply mining is determined by the net supply of the investors, which is calculated by subtracting the total supply from the total borrow. This means that the higher the net supply of the investors, the higher the APY will be. To maximize the APY, investors should look to increase their net supply by borrowing less and supplying more USDD into the JustLend platform.
