The rate-up value depends on the staked amount and nominal interest rate of the Rate-Up Coupon. After the rate-up duration expires or its cap is reached, the Rate-Up Coupon is fully used. There are two types of rate-up caps: Principal and Interest. The Principal Rate-Up Cap indicates the rate-up value based on the principal specified on the coupon. Conversely, the Interest Rate-Up Cap is the maximum interest that the user can earn with rate-up. Once either cap is reached, no further rate-up interest is earned.
