Prime Instance - Restore ETH LTV
01Summary
Proposal to restore ETH's Loan-to-Value (LTV) ratio from 0% to 82% on Aave v3's Prime instance, re-enabling ETH as collateral after it was disabled to prevent wETH/wETH leverage farming exploits. The proposal also updates the ETH Correlated eMode category to make wstETH a collateral asset while keeping wETH borrowable only.
- Type
- parameter change
Key changes
- ETH LTV on Prime instance restored from 0% to 82%(high)
- wstETH added as collateral asset in ETH Correlated eMode category with 93.50% LTV and 95.50% LT(high)
- wETH remains borrowable but no longer collateral in ETH Correlated eMode(medium)
Notable concerns
- Previous ETH LTV was set to 0% to prevent wETH/wETH leverage farming exploits; restoration requires reliance on new Merkl distribution qualification criteria to prevent similar abuse

02Description
Simple Summary
This publication proposes restoring ETH’s LTV to 82% on the Prime instance of Aave v3.
Motivation
With the introduction of liquidity mining rewards for ETH deposits on Prime, some users exploited wETH/wETH leverage to farm rewards. In response, ETH’s LTV was set to 0, preventing new ETH collateral positions while preserving existing user positions.
Transitioning from direct liquidity mining emissions to a periodic Merkl distribution ensures that users leveraging wETH/wETH can be disqualified from rewards. By introducing a qualification criteria, incentives are directed towards users who engage with the protocol as intended.
This proposal focuses on re-enabling ETH collateral positions by restoring the LTV to 82%.
Specification
The LTV for ETH on Prime is to be amended as outlined below:
| Parameter | Current | Proposed |
|---|---|---|
| LTV | 0.00% | 82.00% |
The ETH Correlated eMode category is to be amended as outlined below:
| Parameter | Value | Value |
|---|---|---|
| Asset | wETH | wstETH |
| Collateral | No | Yes |
| Borrowable | Yes | No |
| LTV | 93.50% | 93.50% |
| LT | 95.50% | 95.50% |
| Liquidation Penalty | 1.00% | 1.00% |
