# Testing on Blast Test Networks

You can find the chainid and supporting information for OP Goerli, our test network, [using these endpoints](https://community.optimism.io/docs/useful-tools/networks.html). To obtain ETH and tokens (both ERC-20 and NFT) from faucets, [see here](https://community.optimism.io/docs/useful-tools/faucets.html).

This page shows some additional testing utilities that you might find useful.

### The bridge <a href="#the-bridge" id="the-bridge"></a>

The `OUTb` token is supported by the bridge on Goerli. See [this tutorial <br>](https://github.com/BLASTchain/blast-tutorial/tree/main/cross-dom-bridge-erc20)<br>

# Agent Instructions
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://docs.blastblockchain.com/quick-start/testing-on-blast-test-networks.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.
