# stETH on Aave

{% hint style="info" %}
**News Flash:** On May 19, 2022, the risk parameter for `stETH` as collateral on Aave v2 were changed to a maximum LTV of 69% and a Liquidation Threshold of 81%. [Details can be found here](https://app.aave.com/governance/proposal/75/).
{% endhint %}

The Aave v2 lending protocol supports Lido `stETH` as collateral (but you cannot borrow `stETH` on Aave).

Every token supported by Aave has specific risk parameters / limits when used as collateral:

* **Maximum LTV**. The maximum Loan-to-Value (LTV) ratio is the maximum that can borrowed against the collateral.  The current max LTV for `stETH` is `69%`. This means that you can borrow up to 69% of the value of your deposited `stETH` on Aave.
* **Liquidation Threshold**. The liquidation threshold is the LTV threshold past which your position can be liquidated. The current liquidation threshold for `stETH` is `81%`. This means that if the value of your `stETH` was to decline to the point that the value of your debt now comprised 81% or more of the value of your stETH collateral, then some of your `stETH` could be liquidated and used to pay down your debt. Given that stETH is pegged to the price of ETH, it would have to become significantly de-pegged for this to occur, see the section on [Risk](/basics/risk.md) for more.
* **Health Factor.** The Aave Health Factor is calculated as: `TVL / Liquidation Threshold`. As such, when it goes below `1.0`, you may be subject to liquidation.
