# Flash Loans

**Blueberry Lend** is bringing Flash Loans to our money markets.

Flash Loans allow developers access to undercollateralized loans, provided that the borrowed amount (and fee) is returned within one transaction block.

Flash Loans offer a wide range of use cases, including democratized liquidations, arbitrage, collateral swapping and interest rate swapping.

1. Using Flash Loans devs **interact with BToken contract,** instead of the lending pool.
2. Flash Loan fee is 0.03%

Our markets comply to EIP-3156 interfaces natively. Users should call flashloan on specific market with the following interface:

```
// 
/**
    * @notice Flash loan funds to a given account.
    * @param receiver The receiver address for the funds
    * @param token The loan currency. Must match the address of this contract's underlying 
    * @param amount The amount of the funders to be loaned
    * @param data The other data
    * @return uint 0=success, otherwise a failure (see ErrorReporter.sol for details)
    */
   function flashLoan(
       ERC3156FlashBorrowerInterface receiver,
       address token,
       uint256 amount,
       bytes calldata data
   ) external returns (bool);
    
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://v1.docs.blueberry.garden/lending-protocol/overview/governance/flash-loans.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
