Interest Rates
We use a 2-stage interest rate model, where computation of the interest rate is separated into two stages.
Kinked Interest Rate Model Example
Before utilization reaches the kink level, interest rate is a linear interpolation between
r0 and kink_rate. After utilization goes above the kink level, interest rate is computed as a linear interpolation between kink_rate and full_rate.The parameters,
r0, kink_rate, full_rate and kink for various tokens are listed below:Do note these numbers are tentative and applies only to testnet for now. Mainnet numbers may change.
Token | r0 | kink rate | full rate | kink |
