# Money Streaming (CFA)

## What is the CFA?

The Constant Flow Agreement lets you stream money! What do we mean by streaming? Streaming is a constant by-the-second movement of tokens from a sending account to a receiving account. In a CFA, the sender agrees to have its account balance reduce at a certain per-second rate—called the flow rate—and the receiving party's account balance increase at that flow rate. 

A stream is perpetual and will continue until the sender decides to cancel it or the sender's Super Token balance hits zero. It can also be created, updated, or deleted whenever the sender wants.

**This section will show you how to develop code that interacts with the CFA. For something more conceptual, check out this simple conceptual breakdown** 👇

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://superfluid.gitbook.io/superfluid/developers/constant-flow-agreement-cfa.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.
