Flash Pools
Important parameters and formulas in Wing Flash Pools
The Collateral Factor is a parameter that limits the maximum amount a user can borrow using a specific asset as collateral. Each asset in the Flash Pools has specific values related to their risk, which influences how they are loaned and borrowed. The calibration of the parameters for Wing Project is more aggressive as the Wing ecosystem is mature with some educated users and liquidators. The table below shows the Collateral Factor of each asset.
For example, if a user supplied $1,000 worth of pETH to Flash Pool (Ontology), the maximum amount this user can borrow (borrow limit) is
.
If a borrower's address reaches 100% of its borrow limit, the borrower's collateral assets will be liquidated. Liquidators can repay loans at the discounts listed below and thus earn liquidation bonus.
Reserve factor is a percentage of borrowers paid interest to be deposited in the Wing DAO Community Fund.

Annual Percentage Rate (APR) is the annual interest rate charged to borrowers.
In WIP-15, a kink point was introduced to the interest rate model. The new interest rate model before and after the kink point uses different formulas. The interest rate growth before the kink point is relatively slow, compared to a rapid increase after the kink point.
When the capital utilization rate is
, the corresponding interest rate is
. At the kink point
, the capital utilization rate is
. The basic interest is
, and the interest rate at the kink point is
. When the capital utilization rate is 100%, the interest rate is
.
The capital utilization rate and interest rate follow the model below:
