# iou.list()

[[Source]](https://github.com/ripple/simpleXRPL/blob/95b977b15f8950c5bc076b25165217869c0b06d3/src/verticals/iou.ts#L150)

List every IOU trust line for an account.

## Signature


```ts
iou.list(
  params?: IOUListParams
): Promise<IOUListResult>
```

## Parameters

| Parameter | Type | Required | Description |
|  --- | --- | --- | --- |
| `role` | `'holder' | 'issuer'` | No | Query as `holder` (default) or `issuer`. |
| `account` | `string` | No | The account whose trust lines to list. Defaults to the primary signer's account. |


## Returns

Resolves to an `IOUListResult`, where `ious[i]` corresponds to `data[i]`:

| Field | Type | Description |
|  --- | --- | --- |
| `ious` | `readonly string[]` | The `iouID` of each line, composable into the write operations. |
| `data` | `readonly IOUTrustLine[]` | The shaped trust lines. See [iou.retrieve](/docs/simplexrpl/references/verticals/iou/retrieve#ioutrustline) for `IOUTrustLine`. |


## Underlying XRPL request

Read-only — no signer is required and nothing is submitted. Queries the ledger with [account_lines](https://xrpl.org/docs/references/http-websocket-apis/public-api-methods/account-methods/account_lines).

## Example


```ts
const { data } = await client.iou.list()

for (const line of data) {
  console.log(line.currency, line.balance)
}
```
