• Compute borrow rate from utilization.

• Compute supply rate from borrow rate and reserve factor.

• Provide a simple, deterministic interest model.

  • Returns yearly borrow rate (scaled 1e6).

• get_supply_rate(cash, borrows, reserves, reserve_factor) -> rate_scaled

  • Returns yearly supply rate (scaled 1e6).
