# 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.
xRHEA Lending Boost interface with boost ratio range and lock-up period up to 6 months
### 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
| 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
| 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
* 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
* Updated Reward Allocation:
* Alice: 76.34 wNEAR/day
* Bob: 6.2 wNEAR/day
* Charlie: 117.44 wNEAR/day
