# [ARFC] Deprecate Aave V2 AMM Market - Step 2

## Simple Summary
Since the community approved to deprecate the v2 AMM market within the Deprecate Aave v2 AMM Market forum [post](https://governance.aave.com/t/arfc-deprecate-aave-v2-amm-market/12830). Gauntlet is providing further parameter recommendations to motivate the remaining v2 AMM users to migrate to v3 markets.

Gauntlet recommends to increase reserve factor to 99% for the following assets:

|  Asset    | Current RF | Recommended RF |
| ---- | ---------- | -------------- |
| WETH | 0.1        | 0.99           |
| DAI  | 0.1        | 0.99           |
| USDC | 0.1        | 0.99           |
| WBTC | 0.2        | 0.99           |
| USDT | 0.1        | 0.99           |

Gauntlet recommends to adjust the IR params for the following assets:
| Asset | Current Variable Base | Recommended Variable Base | Current Variable Slope1 | Recommended Variable Slope1 |
| ----- | --------------------- | ------------------------- | ----------------------- | --------------------------- |
| WETH  | 0                     | 0.06                      | 0.08                    | No Change                   |
| DAI   | 0                     | 0.04                      | 0.04                    | 0.1                         |
| USDC  | 0                     | 0.04                      | 0.04                    | 0.1                         |
| WBTC  | 0                     | 0.05                      | 0.08                    | No Change                   |
| USDT  | 0                     | 0.06                      | 0.04                    | 0.1                         |


## Specifications
Gauntlet aims to reduce the remaining $94k borrow position within the market. Here are the remaining liquidity markets with outstanding borrow positions:
| Asset | Supply  | Borrow  |
| ----- | ------- | ------- |
| WETH  | $581k   | $26.7k  |
| DAI   | $59.38K | $24.43K |
| USDC  | $54.37K | $26.79K |
| WBTC  | $37.31K | $9.12K  |
| USDT  | $22.64K | $7.23K  |

Gauntlet proposes to adjust the IR parameters to increase borrow APR to motivate borrowers to pay back their outstanding positions. 

### Current IR Params and Current Borrow APR

### Recommended IR Params and Projected Borrow APR
| Asset | Variable Base | Variable Slope1 | Variable Slope2 | Uoptimal | Current Utilization | New Borrow APR |
| ----- | ------------- | --------------- | --------------- | -------- | ------------------- | -------------- |
| WETH  | 0.06          | 0.08            | 1               | 0.65     | 4.60%               | 6.57%          |
| DAI   | 0.04          | 0.1             | 0.75            | 0.8      | 41.14%              | 9.14%          |

| WBTC  | 0.05          | 0.08            | 1               | 0.65     | 24.44%              | 8.01%          |
| USDT  | 0.06          | 0.1             | 0.75            | 0.8      | 31.93%              | 9.99%          |

The increase in reserve factor will reduce any earn interest for suppliers and motivate them to remove their positions as well. 

### Next Steps
Welcome community feedback and will put up snapshots for each of the collateral asset next week.
