# Dispatch Transaction
The `dispatch()` function allows you to quickly sign and send a transaction to the network in a bundled format. It is best for smaller datas and contract interactions. If the bundled transaction cannot be submitted, it will fall back to a base layer transaction. The function returns the [result](#dispatch-result) of the API call.
| Argument | Type | Description |
| ------------- | ------------------------------------------------------------------------------------------------------------------------ | ------------------------------------------------------------ |
| `transaction` | [`Transaction`](https://github.com/arweaveTeam/arweave-js#transactions) | A valid Arweave transaction instance (**without a keyfile**) |
| `options?` | [`SignatureOptions`](https://github.com/ArweaveTeam/arweave-js/blob/master/src/common/lib/crypto/crypto-interface.ts#L3) | Arweave transaction signature options |
{% hint style="info" %}
**Note:** This function requires the [`DISPATCH`](/api/connect.md#permissions) permission.
{% endhint %}
{% hint style="info" %}
**Note:** The `options` argument is optional, if it is not provided, the extension will use the default signature options (default salt length) to sign the transaction.
{% endhint %}
{% hint style="warning" %}
**Note:** If you are trying to sign a larger piece of data (5 MB <), make sure to notify the user to not switch / close the browser tab. Larger transactions are split into chunks in the background and will take longer to sign.
{% endhint %}
{% hint style="warning" %}
**Note:** The function uses the default bundler node set by the user or the extension. Consider using the [`signDataItem()`](/api/sign-dataitem.md) function to submit data to a custom bundler.
{% endhint %}
## Dispatch result
The `dispatch()` function returns the result of the operation, including the ID of the submitted transaction, as well as if it was submitted in a bundle or on the base layer.
```ts
export interface DispatchResult {
id: string;
type?: "BASE" | "BUNDLED";
}
```
## Example usage
```ts
import Arweave from "arweave";
// create arweave client
const arweave = new Arweave({
host: "ar-io.net",
port: 443,
protocol: "https"
});
// connect to the extension
await window.arweaveWallet.connect(["DISPATCH"]);
// create a transaction
const transaction = await arweave.createTransaction({
data: 'Hello permanent world! This was signed via Wander!!!'
});
// dispatch the tx
const res = await window.arweaveWallet.dispatch(transaction);
console.log(`The transaction was dispatched as a ${res.type === "BUNDLED" ? "bundled" : "base layer"} Arweave transaction.`)
```
