# BrowserProvider

A **BrowserProvider** is intended to wrap an injected provider which adheres to the
[EIP-1193](https://eips.ethereum.org/EIPS/eip-1193) standard, which most (if not all) currently do.

## Extends

* [`JsonRpcApiProvider`](/sdk/content/classes/JsonRpcApiProvider)

## Constructors

### new BrowserProvider()

```ts theme={null}
new BrowserProvider(ethereum, network?): BrowserProvider
```

Connect to the `ethereum` provider, optionally forcing the `network`.

#### Parameters

| Parameter  | Type                                                         | Description                |
| :--------- | :----------------------------------------------------------- | :------------------------- |
| `ethereum` | [`Eip1193Provider`](/sdk/content/interfaces/Eip1193Provider) | The EIP-1193 provider.     |
| `network`? | [`Networkish`](/sdk/content/type-aliases/Networkish)         | The network to connect to. |

#### Returns

[`BrowserProvider`](/sdk/content/classes/BrowserProvider)

#### Overrides

[`JsonRpcApiProvider`](/sdk/content/classes/JsonRpcApiProvider).[`constructor`](/sdk/content/classes/JsonRpcApiProvider#constructors)

## Accessors

### connect

```ts theme={null}
get connect(): FetchRequest[]
```

Get the list of connected FetchRequests.

#### Returns

[`FetchRequest`](/sdk/content/classes/FetchRequest)\[]

The list of connected FetchRequests.

[providers/abstract-provider.ts:1026](https://github.com/dominant-strategies/quais.js/blob/c1c12d43f9d34c6baad2b0542bd6d0acd6fefcbf/src/providers/abstract-provider.ts#L1026)

***

### destroyed

```ts theme={null}
get destroyed(): boolean
```

If this provider has been destroyed using the [**destroy**](/sdk/content/classes/AbstractProvider#destroy) method.

Once destroyed, all resources are reclaimed, internal event loops and timers are cleaned up and no further
requests may be sent to the provider.

#### Returns

`boolean`

#### Source

[providers/abstract-provider.ts:2545](https://github.com/dominant-strategies/quais.js/blob/c1c12d43f9d34c6baad2b0542bd6d0acd6fefcbf/src/providers/abstract-provider.ts#L2545)

***

### paused

```ts theme={null}
get paused(): boolean
```

Whether the provider is currently paused.

A paused provider will not emit any events, and generally should not make any requests to the network, but that
is up to sub-classes to manage.

Setting `paused = true` is identical to calling `.pause(false)`, which will buffer any events that occur while
paused until the provider is unpaused.

#### Returns

`boolean`

Whether the provider is paused.

***

### pollingInterval

```ts theme={null}
get pollingInterval(): number
```

Get the polling interval.

#### Returns

`number`

The polling interval.

***

### provider

```ts theme={null}
get provider(): this
```

Returns `this`, to allow an **AbstractProvider** to implement the [Contract Runner](../classes/ContractRunner)
interface.

#### Returns

`this`

***

### ready

```ts theme={null}
get ready(): boolean
```

Returns true only if the JsonRpcApiProvider.\_start | **\_start** has been called.

#### Returns

`boolean`

True if the provider is ready.
