# How to Bridge an ERC-20 Token to Arbitrum

{% embed url="<https://www.youtube.com/watch?v=6SEqpkPPIgQ>" %}

Bridging tokens to Arbitrum allows you to take advantage of lower fees and faster transactions on this Layer 2 scaling solution. Follow these steps to bridge your ERC-20 tokens from Ethereum mainnet to Arbitrum:

1. **Connect your wallet**
   * Use a compatible wallet like MetaMask
   * Ensure you have ETH for gas fees on both networks
2. **Choose a bridge**
   * Popular options include the Arbitrum Bridge or third-party bridges like Hop or Across
   * For this tutorial, we'll use the official Arbitrum Bridge ([bridge.arbitrum.io](https://bridge.arbitrum.io/))
3. **Select token and amount**
   * Choose the ERC-20 token you want to bridge
   * Enter the amount you wish to transfer
4. **Approve the token**
   * If it's your first time bridging this token, you'll need to approve it
   * This requires a separate transaction
5. **Initiate the bridge**
   * Confirm the transaction in your wallet
   * Pay the Ethereum gas fee
6. **Wait for confirmation**
   * The bridging process typically takes about 10 minutes
   * You can track the status on Arbiscan
7. **Add Arbitrum network to your wallet**
   * If you haven't already, add Arbitrum to your wallet
   * You can find network details on Arbitrum's website
8. **Add the token to your Arbitrum wallet**
   * Import the token address on Arbitrum
   * You should now see your bridged tokens

By following these steps, you can efficiently bridge your ERC-20 tokens to the Arbitrum network and begin exploring its ecosystem.

Remember to always double-check addresses and amounts before confirming transactions. Happy bridging!

## 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.untrading.org/tutorials/web3/how-to-bridge-an-erc-20-token-to-arbitrum.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.
