# 3. Network Configuration

To interact with the FreCx blockchain, developers must understand how the network is configured and how to connect to it. Network configuration defines the parameters that govern how nodes communicate, how transactions are processed, and how applications interact with the blockchain.

Unlike traditional centralized systems where endpoints are abstracted away, blockchain networks require explicit configuration, including:

* RPC endpoints for communication
* Chain IDs for network identification
* environment selection (testnet vs mainnet)

Proper configuration ensures that applications interact with the correct network and that transactions are executed in the intended environment.

## 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.frequencychain.org/3.-network-configuration.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.
