# LoanBroker

[[Source]](https://github.com/XRPLF/rippled/blob/develop/include/xrpl/protocol/detail/ledger_entries.macro#L500-L518)

Attention
Lending Protocol and Single Asset Vaults are disabled on Devnet. You have two options for testing these features:

1. Run `rippled` in [stand-alone mode](https://xrpl.org/docs/concepts/networks-and-servers/rippled-server-modes#stand-alone-mode) and enable `LendingProtocol` and `SingleAssetVault` in the [rippled.cfg file](https://xrpl.org/docs/infrastructure/testing-and-auditing/test-amendments).
2. Connect to the Lending Protocol-specific Devnet at `https://lend.devnet.rippletest.net:51234/`.


A `LoanBroker` ledger entry defines the configuration and state of a lending protocol instance. It tracks details such as fees and first-loss capital cover. You can create a `LoanBroker` object with the [`LoanBrokerSet`](/docs/xls-66d-lending-protocol/reference/transactions/loanbrokerset) transaction.

The `LoanBroker` entry is tracked in an [Owner Directory](https://xrpl.org/directorynode.html) owned by the account that submitted the `LoanBrokerSet` transaction. To facilitate lookup, it is also tracked in the `OwnerDirectory` of the associated vault's *pseudo-account*.

Note
The lending protocol uses the pseudo-account of the associated `Vault` entry to hold the first-loss capital.

*(Requires the [Lending Protocol amendment](https://github.com/Tapanito/XRPL-Standards/tree/xls-66-lending-protocol/XLS-0066d-lending-protocol) )*

##  Fields

In addition to the [common ledger entry fields](https://xrpl.org/docs/references/protocol/ledger-data/common-fields/),  entries have the following fields:

| Name | JSON Type | Internal Type | Required? | Description |
|  --- | --- | --- | --- | --- |
| `PreviousTxnID` | String | Hash256 | Yes | Identifies the transaction ID that most recently modified this object. |
| `PreviousTxnLgrSeq` | Number | UInt32 | Yes | The sequence of the ledger that contains the transaction that most recently modified this object. |
| `Sequence` | Number | UInt32 | Yes | The transaction sequence number that created the LoanBroker. |
| `LoanSequence` | Number | UInt32 | Yes | A sequential identifier for `Loan` ledger entires, incremented each time a new loan is created by this `LoanBroker`. |
| `OwnerNode` | Number | UInt64 | Yes | Identifies the page where this item is referenced in the owner's directory. |
| `VaultNode` | Number | UInt64 | Yes | Identifies the page where this item is referenced in the `Vault` pseudo-account owner's directory. |
| `VaultID` | String | Hash256 | Yes | The ID of the vault that provides the loaned assets. |
| `Account` | String | AccountID | Yes | The address of the `LoanBroker` pseudo-account. |
| `Owner` | String | AccountID | Yes | The account address of the vault owner. |
| `Data` | String | Blob | No | Arbitrary metadata about the vault. Limited to 256 bytes. |
| `ManagementFeeRate` | Number | UInt16 | No | The fee charged by the lending protocol, in units of 1/10th basis points. Valid values are 0 to 100000 (inclusive), representing 0% to 100%. |
| `OwnerCount` | Number | UInt32 | Yes | The number of active loans issued by the LoanBroker. |
| `DebtTotal` | Number | Number | Yes | The total asset amount the protocol owes the vault, including interest. |
| `DebtMaximum` | Number | Number | Yes | The maximum amount the protocol can owe the vault. The default value of `0` means there is no limit to the debt. |
| `CoverAvailable` | Number | Number | Yes | The total amount of first-loss capital deposited into the lending protocol. |
| `CoverRateMinimum` | Number | UInt32 | Yes | The 1/10th basis point of the `DebtTotal` that the first-loss capital must cover. Valid values are 0 to 100000 (inclusive), representing 0% to 100%. |
| `CoverRateLiquidation` | Number | UInt12 | Yes | The 1/10th basis point of minimum required first-loss capital that is moved to an asset vault to cover a loan default. Valid values are 0 to 100000 (inclusive), representing 0% to 100%. |


##  Flags

There are no flags defined for  ledger entries.

##  Reserve

`Loan` entries incur one owner reserve from the account that creates it.

##  ID Format

The ID of a `LoanBroker` entry is the [SHA512-Half][] of the following values, concatenated in order:

- The `LoanBroker` space key `0x006C`.
- The [AccountID](https://xrpl.org/docs/references/protocol/binary-format/#accountid-fields) of the account submitting the `LoanBrokerSet` transaction.
- The transaction `Sequence` number. If the transaction used a [Ticket][], the `TicketSequence` value is used instead.
