# Submitting Loan Requests

Borrowers can browse the [Teller Protocol Marketplace webapp](https://app.teller.org) or the `MarketRegistry` contract to find a market that meets their needs (Auto, Home, Personal).

Once a market is chosen, they can submit their bid request to the `TellerV2` contract with the function defined below.

### Submitting a Loan Request

```solidity
/**
 * @notice Function for a borrower to create a bid for a loan.
 * @param _lendingToken The lending token asset requested to be borrowed.
 * @param _principal The principal amount of the loan bid.
 * @param _duration The length of time, in seconds, the loan will remain active.
 * @param _APY The proposed interest rate for the loan bid.
 * @param _paymentCycle The recurrent length of time before which a payment is due.
 * @param _metadataURI The URI for additional borrower loan information as part of loan bid.
 */
function submitBid(
    address _lendingToken,
    uint256 _marketplaceId,
    uint256 _principal,
    uint32 _duration,
    uint16 _APY,
    uint32 _paymentCycle,
    bytes32 _metadataURI,
    address _receiver
)
```

The `_metadataURI` submitted by a borrower along with the proposed loan terms (`_APY`, `_principal`, `_lendingToken`, etc), needs to correspond with the metadata required by the market. Depending on the market, this could be in the form of a verified credit report from the relative credit bureau, identity, or other relevant data.

### Cancelling a Loan Request

```solidity
/**
 * @notice Function for users to cancel a bid.
 * @param _bidId The id of the bid to be cancelled.
 */
function cancelBid(uint256 _bidId)
```

Borrowers who wish to cancel their bid request prior to it's expiration, can do it by submitting a transaction to the protocol with the `_bidId`.
