Supply APY: an annualized earning rate
APY means annual percentage yield. Supply APY expresses a rate over a year, including the effect of compounding used in that calculation. It is not a daily percentage payment and it is not a guaranteed future return.
The rate can change while tokens are supplied. The token’s dollar price and transaction costs can also change ur overall result.
Borrow APY: the annualized cost
Borrow APY describes an annualized borrowing rate. Interest increases what the position owes. A lower rate today does not guarantee the same cost next month.
In V4, collateral can affect borrowing costs through a risk premium. Read the position’s displayed rate and preview rather than adding unrelated percentage fields together. The Borrowing costs guide explains the distinction.
Net APY and net balance are different
Portfolio displays a net APY supplied by the protocol data alongside the position’s net balance. A rate and a dollar balance have different units. Net APY is not a record of cash profit u have already earned.
Do not subtract two headline APYs and assume the result is your return: the supplied and borrowed amounts may differ, and rates can change. Use the position-specific information and inspect the underlying supply and debt.
Read the history in context
Asset route cards request the last month of supply and borrow rate history. The compact display uses recent samples and scales each series to its own values. A taller bar is larger within that series, not necessarily larger than a bar on another chart.
There are currently no exact-date hover values or selectable chart timeframes. Missing history is not evidence of a zero rate. Compare routes using the current numbers and settings as well as their history.
