This vault earns by buying sUSDe at a discount and realizing the spread via Ethena unstaking. <br>

{% stepper %}
{% step %}

#### Buy staked USDe at a discount on a DEX.

**Example:** pay 9,997 USDe for 10,000 USDe worth of sUSDe.
{% endstep %}

{% step %}

#### Start the unstake process (7-day countdown)

{% endstep %}

{% step %}

#### Wait 7 days

{% endstep %}

{% step %}

#### Receive the full USDe value (get 10,000 USDe back)

{% endstep %}

{% step %}

#### Profit = 3 USDe (minus fees)

{% endstep %}
{% endstepper %}

**Target APY:** \~15% annualized (or higher than staking)
