# Vault Synopsis

The Liquid Leverage sUSDe/USDe vault provides liquid leveraged exposure to sUSDe native yield, USDe lending rates and Merkl rewards on Ethereum.

#### Strategy Overview

The vault holds sUSDe and USDe tokens as collateral on Aave V3 (Core) and borrows USDT to achieve liquid leveraged exposure to the spread on the supply/lend yields. The depositor's vault share remains valid across all incentive campaign periods.

The yield source is the difference between the sum of yield from staking USDe, Merkl reward yields and the USDT borrow cost on the lending market. As long as the borrow costs are lower than the reward yields, the vault generates a positive yield spread.

$$
\text{Yield Spread} = \text{(Staking yield + Merkl Reward Yields)} \times \text{Leverage} - \text{Borrow Rate} \times (\text{Leverage} - 1)
$$

{% hint style="info" %}
Liquid Leverage addresses the 7-day unstaking cooldown issue for sUSDe users. By maintaining at least half the position in USDe and employing leverage, it creates a loop that keeps a portion of the funds liquid, free from the 7-day cooldown constraint.

Additional adapters (e.g., Morpho, Euler) may be added in the future to access alternative borrow liquidity. See [The Adapter Layer](/the-third-fold-opal/how-does-an-opal-vault-work.md#the-adapter-layer) for details on how new adapters are deployed and migrated.
