# TxFlash | Robinhood Chain Fast Feed

[TxFlash](https://txflash.io) delivers Robinhood Chain sequencer transactions over persistent, low-latency TCP connections.

Transactions are delivered as complete binary records for latency-sensitive applications and node integrations.

## Start here

* [Getting started](/getting-started.md): prepare your network and receive your first frame.
* [Robinhood Chain feed](/robinhood-fast-feed.md): understand the available data and delivery model.
* [Connection guide](/connection-guide.md): configure a production connection.
* [DIRECT protocol](/direct-protocol.md): implement the binary decoder.
* [Troubleshooting](/troubleshooting.md): diagnose connection and framing errors.

## Delivery model

```
Multi-stream relay
        |
        v
Persistent TCP DIRECT feed
        |
        v
Your node or transaction consumer
```

The customer connection uses an uncompressed binary protocol over TCP. It does not add WebSocket, TLS, JSON, or Base64 processing between the relay and the consumer.

## 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://docs.txflash.io/overview.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.
