# xRHEA Lending Boost

### Overview

xRHEA Lending Boost allows users to lock xRHEA tokens in exchange for boosted incentive rewards on Rhea Lending. The longer the lock-up period, the greater the boost — up to a maximum of 6 months.

Note: Boost only affects incentive rewards. It does not impact base lending interest rates.

### How it works

Lock xRHEA → Earn Weight → Get Boosted Rewards

The program operates in two sections:

1. Weight Algorithm – Calculates your Weight based on the amount and duration of xRHEA locked.
2. Farming Multiplier Algorithm – Converts your Weight into a reward boost factor.

### 1. Weight Algorithm

Your Weight is determined by:

Where:

* Y = Weight
* X = The amount of xRHEA locked
* D = Lock duration (from 30 to 180 days)
* D\_min = 30
* D\_max = 180
* M\_min = 10,000

M\_max = 30,000

### Example Weight Table&#x20;

| xRHEA Locked | Lock Duration | Weight Received |
| ------------ | ------------- | --------------- |
| 100 xRHEA    | 1 Month       | 100             |
| 100 xRHEA    | 3.5 Months    | 200             |
| 100 xRHEA    | 6 Months      | 300             |

> The longer you lock, the higher the Weight (up to 3x boost at 180 days)

### 2. Farming Multiplier Algorithm

Once Weight is calculated, it’s converted into a Farming Multiplier, which boosts the user’s share of the incentive rewards pool.

Where:

* Y = user's Weight
* boost\_suppress\_factor = 100
* base = 2137469933345.874131511402299392

#### Farming Multiplier Table

| Weight Amount | Farming Multiplier |
| ------------- | ------------------ |
| 500           | 1.056x             |
| 5,000         | 1.137x             |
| 50,000        | 1.218x             |
| 500,000       | 1.300x             |
| 5,000,000     | 1.381x             |
| 50,000,000    | 1.462x             |

### Example: How Rewards Are Distributed

Imagine the USDC lending pool emits 200 wNEAR/day in incentive rewards.

#### Case 1: Boosted Users Only&#x20;

| User  | Supplied USDC | Weight  | Multiplier | Boosted Shares |
| ----- | ------------- | ------- | ---------- | -------------- |
| Alice | 500           | 500,000 | 1.300x     | 650            |
| Bob   | 50            | 500     | 1.056x     | 52.8           |

* Total Boosted Shares: 702.8<br>
* Reward Allocation:
  * Alice: 184.96 wNEAR/day
  * Bob: 15.2 wNEAR/day

#### Case 2:  New User Without xRHEA Lock

| User    | Supplied USDC | Weight | Multiplier | Boosted Shares |
| ------- | ------------- | ------ | ---------- | -------------- |
| Charlie | 1,000         | 0      | 1.000x     | 1,000          |

* New Total Boosted Shares: 1,702.8<br>
* Updated Reward Allocation:
  * Alice: 76.34 wNEAR/day
  * Bob: 6.2 wNEAR/day
  * Charlie: 117.44 wNEAR/day
