# ParaSwap SRB

PSPSRB is a benchmark that represents the annualized staking rate for the PSP token. Due to the tokenomics of this token, its value is determined by the reward rate of the most popular reward option, which holds more than the supermajority of the locked tokens.

PSPSRB is calculated and published by Staking Rewards via the [PSP Profile](https://www.stakingrewards.com/asset/paraswap) and [Data API](https://www.stakingrewards.com/data-api).

> **TL;DR:** ParaSwap staking rewards come from protocol fees collected during each 28-day epoch. The reward rate equals predicted rewards times reward share, divided by investment value, and annualized.

$$
PSPSRB = (pr \* rs)/ iv \* t\_y / t\_e

### Paraboost Score:

The paraboost score is a multiplier that represents your share of the reward distribution when compared to the total paraboost score of all stakers.

$$paraboostScore = tokenScore \* myBoost$$

$$myBoost = tb1 \* tb2 \* mb \* pb \* bb \* rb1 \* rb2$$

$$tokenScore = sePSP1 + 2.5 \* sePSP2$$

A minimum amount of 10k sePSP2 amount is required for it to be counted for the boost.

### Revenue Share

$$myRevenueShare = ps / ( tp + ps)$$

| Metric | Name               | Description                                       |
| ------ | ------------------ | ------------------------------------------------- |
| *ps*   | My Paraboost Score | The paraboost score for the current epoch.        |
| *tp*   | Total Paraboost    | The total paraboost score from all staking users. |

### Final APR adjusted to user input

We derive this formula from the starting formula and the revenue share:

$$myBasicPoolAPR = pr \* (userInput \* pb) \* ((plp1 +userInput) / (plp1 + userInput + 2.5 \* plp2)/ (userInput \* price) \* t1 / e1$$

$$myBasicPoolAPR = pr \* (2.5 \* userInput \* pb) \* (2.5 \* (plp2 +userInput) / (plp1 + 2.5 \* (plp2 + userInput)/ (userInput \* price / 0.8) \* t1 / e1$$
