Supply earns APY
When you supply an asset, you earn interest on your balance. Earnings compound into your supplied amount over time. You do not need to claim rewards manually for base lending interest. Your supply APY depends on:- How much of the pool is borrowed (utilization)
- The borrow rate for that asset
- The reserve factor (the share of borrower interest kept by the protocol)
Borrow pays APY
When you borrow, you owe the borrowed amount plus accruing interest. Interest adds to your debt automatically. Repay anytime to reduce what you owe. Your borrow APY rises when utilization is high. Heavy demand for loans pushes rates up across the curve.Utilization in plain terms
Utilization is the share of supplied liquidity that borrowers have taken.| Utilization | Typical effect |
|---|---|
| Low | Cheaper to borrow, lower supply APY |
| Moderate | Balanced rates for borrowers and suppliers |
| High | Costlier borrows, higher supply APY |
