# 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>
