# send()

## Introduction

The `.send()` function simply sends all the `<EtherspotBatches />`, which contain all `<EtherspotBatch />` and `<EtherspotTransaction />` components to the blockchain via the Etherspot platform.

{% hint style="warning" %}
**You must always estimate before sending**

Estimating first performs imporant transaction cost calculations that are required before sending.
{% endhint %}

## How to use

Whenever you are ready to send your transaction to the blockchain, you simply need to call .send() as shown below.

```javascript
import {
  useEtherspotTransactions,
} from '@etherspot/transaction-kit';

// Later in the main component function...

const { send } = useEtherspotTransactions();

// And when you're ready to end your transaction(s)...

send(); // This is also a Promise

// Your transactions are now being sent to the blockchain
```

## :tada: Congratulations

By calling the above function, you have sent the transactions to the Etherspot platform, and we'll take care of it from here to ensure that the transactions are executed on the blockchain.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://v1.etherspot.io/transaction-kit/react-hooks/useetherspottransactions/send.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
