# Bridge GPT - L1 > L2

If you own GPT tokens on Ethereum L1 then you'll need to bridge to GPT tokens on GPT Mainnet L2 in order to use Neuraswap.&#x20;

GPT Protocol has a bridge that allows users to swap back and forth from L1 to L2 and vice versa seamlessly.

## How to Bridge

1. Go to <https://bridge.gptprotocol.io/>
2. Connect your Metamask wallet.
3. In the top section you will see a button "Add to Metamask". You'll want to click that in order to add GPT Mainnet (L2) to your list of Metamask networks.
4. In the middle section of the page make sure the network you select is Ethereum and the token is GPT. Your balance should now auto populate with your current balance of GPT on Ethereum L1.
5. Now enter the amount of GPT you want to bridge to "GPT Mainnet" and click continue. Your page should look very similar to below.
6. Now click the "Continue" button to confirm the bridge.

## Confirm The Bridge

1. You will now see a page like the one below. If everything looks good, go ahead and click the "Bridge" button.
2. You will then be asked to switch networks and sign for the transaction in Metamask. Go ahead do this to initiate the bridge from L1 > L2.

## That's it!

1. It will now take you to the activity page in order to view your current and past transactions.&#x20;
2. It takes a few minutes but once the transaction settles it will go from Processing > Completed.
3. Once completed you should now see your GPT balance on GPT Mainnet (L2) in Metamask like in the second image below.

# 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://neuraswap.gitbook.io/neuraswap/welcome/neuraswap-tokens/gpt/bridge-gpt-l1-greater-than-l2.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.
