About
What it answers, and for whom.
Aave sets each asset's rates from one input, utilization: the share of supplied assets that is borrowed. As utilization rises, the borrow rate climbs along the asset's rate curve, steeply past its optimal point, and suppliers earn the interest borrowers pay, less the reserve factor. This dashboard reads both rates and utilization for every asset on every Aave market.
Pick an asset to compare its rates across chains, or a market to see all of its assets at once. The history shows how rates followed utilization over the last 90 days and when governance changed a rate curve or a reserve factor. Every figure is read from the market's contracts at a named block, with the call behind it.
Method
How it will be measured.
Every figure will be read at a block, kept with its source and its exact read, and open a receipt anyone can re-check.
How receipts work →- Rates come from Pool.getReserveData(asset): liquidityRate for suppliers and variableBorrowRate for borrowers, yearly rates stored in ray units and converted to APY with per-second compounding.
- Utilization is total variable debt over total supplied for the reserve, from variableDebtToken and aToken totalSupply at the same block.
- Realized supply yield and borrow cost over a period come from growth in the reserve's liquidityIndex and variableBorrowIndex between two pinned blocks, which captures every rate change in between.
- Rate curve and reserve factor changes are read from PoolConfigurator events and marked on the history.
- Daily history uses the first block after 00:00 UTC; rewards paid in other tokens are not part of the APY and are noted where they exist.

Questions
Questions people ask.
How are Aave interest rates set?
By each asset's interest rate model. The borrow rate rises with utilization, gently up to an optimal level and steeply beyond it, which pulls utilization back by drawing in supply and discouraging new loans. The supply rate is the borrow interest shared among suppliers, less the reserve factor.
What is the difference between APR and APY on Aave?
Aave's contracts store rates as yearly rates without compounding, an APR. Interest accrues every second, so the effective yearly return, the APY, is slightly higher. This dashboard shows APY and names the conversion it used.
Why is the supply rate lower than the borrow rate?
Only the borrowed part of a reserve earns interest, and the reserve factor sends a share of that interest to the Aave treasury. The supply rate is therefore the borrow rate times utilization, less the treasury's share.
Why do Aave rates differ between chains?
Each chain runs its own market with its own suppliers, borrowers and rate settings, so the same asset can be in high demand on one chain and mostly idle on another. Rates move toward each other only when users move funds between markets.
Does the APY include rewards?
No. The rates shown are what the protocol pays and charges in the asset itself. Incentive programs that pay other tokens are listed separately where they exist, because they change often and depend on the reward token's price.
- Utilization
- The share of an asset's supplied amount that is currently borrowed.
- Reserve factor
- The share of borrowers' interest kept by the Aave treasury instead of paid to suppliers, set per asset by governance.
- Optimal utilization
- The point on an asset's rate curve beyond which the borrow rate rises steeply, set per asset.
- Ray
- Aave's fixed-point unit with 27 decimals, used to store rates and indexes on-chain.
