Collateral Factor in Flash Pool
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
.

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:
