This strategy earns USDC lending interest on Aave and borrows ETH to generate additional ETH liquid staking yields.

By swapping borrowed ETH for rETH, this strategy earns the the difference between rETH liquid staking yields and ETH borrow interest. Liquid staking yields accrues natively to the liquid staked token and is reflected in rETH price always appreciating against ETH.

## Strategy

{% tabs %}
{% tab title="Main strategy" %}

1. Lend all $USDC - Aave
2. Borrow $WETH
   1. 62.5% of collateral value for 20% buffer
3. Swap $WETH → $rETH
   {% endtab %}

{% tab title="Exit Strategy" %}

1. Swap $rETH → $WETH
2. Repay $WETH debt - Aave
3. Withdraw $USDC collateral
4. Close remaining debt
5. Swap all to withdraw token
   {% endtab %}
   {% endtabs %}
