# Aave Flash Loan

### Recursive Leverage Simulation

Rather than recursively leveraging by incrementally borrowing, staking, and depositing, the magic of SuperStaker simulates 15 levels of recursive leverage, and calculates the final amount of deposited `stETH` and `WETH` debt. This simulation happens in your browser, before any transactions are sent. Once the final loan amount is calculated, an Aave Flash Loan is trigger for the full amount.

### Flash Loan

{% hint style="info" %}
**What is a flash loan?** A flash loan is a loan that is usually repaid within the same transaction, and thus no collateral is required. Some types of flash loans -- as used by SuperStaker -- are not repaid at the end of the transaction, but rather incur debt as long as sufficient collateral is supplied before the end of the same transaction.
{% endhint %}

### Stake ETH with Lido

Once the requested `WETH` loan has been provided to SuperStaker, the WETH is unwrapped to native `ETH`. This `ETH` is then added to the `ETH` you sent initially and the combined amount is staked via LIDO, returning 1 `stETH` for each `ETH` staked.

### Deposit stETH with Aave

The final step is to deposit the stETH as collateral on Aave against the debt triggered by the flash loan.

### SuperStaker works on your Behalf

The above steps are taken on your behalf, and you can then go the Aave Dashboard and see both the supplied `stETH` and borrowed `WETH`.  The SuperStaker contract is designed to have Zero TVL.
