# CrossFi Borrow (Flashloan)

## **What is CrossFi Borrow?**

The Borrow feature update in the CrossFi DApp now empowers you to create sFIL and borrow cFIL with sFIL as collateral. sFIL and cFIL are both FIL (Filecoin) synthetics.

## **What is sFIL?**

sFIL is Filecoin synthetic asset that acts as a certificate created by miners' mortgaged storage power.
 Borrowers pledge the storage power of the node, and sFIL is generated according to the pledged amount.

## **Borrower Nodes FAQs**

*How can I get a loan?*

sFIL holders can borrow cFIL with sFIL as collateral. For example, assuming that the collateral ratio is 60%, the maximum number of cFILs a user can borrow after a mortgage of 10,000 sFIL is 60% of 10000 = 6,000.

*How do I reclaim effective storage power?*

Miners can recover effective storage power by sending sFIL to the designated address.

*How much is the loan interest?*

The borrower calculates the interest in real-time as soon as the loan begins. For example, assuming that the loan interest rate is 60%, it is calculated as loan interest = loan cFIL quantity \* 60% \* loan days/365.
