# Mint

## Mint with ERC20

In order to provide funds to the pool, call `mint` on the respective iToken contract. This will take your deposit and give you iTokens in return. The function retrieves the tokens from the message sender, so make sure to first approve the loan token contract to access your funds. 

```solidity
function mint(address receiver, uint256 depositAmount, bool useLM) external nonpayable nonReentrant globallyNonReentrant 
returns(uint256 minted)
```
