🌉How To Bridge To Arbitrum One

Bridging ETH to the Arbitrum One Network: A Comprehensive Guide

With the rise of Layer 2 scaling solutions, the Arbitrum One Network has caught the attention of the crypto community due to its ability to facilitate faster and more cost-effective Ethereum transactions. If you're looking to utilize platforms on the Arbitrum network, the first step is to bridge your ETH from Ethereum Mainnet to the Arbitrum One Network. This article provides a step-by-step guide on how to do exactly that.


Before we proceed, ensure you have:

  1. MetaMask Wallet: Installed on your Chrome browser or mobile device. This will serve as your bridge to transfer assets between Ethereum and Arbitrum.

  2. Ethereum (ETH): A sufficient balance in your MetaMask wallet to cover gas fees for the bridging transaction on Ethereum Mainnet.

  3. Arbitrum One Network Added to MetaMask: If you haven't added the Arbitrum network to your MetaMask, refer to our previous article on how to add the network.

Step-by-Step Guide to Bridging ETH to Arbitrum One:

1. Navigate to the Official Arbitrum Bridge Portal:

Open your web browser and go to the official Arbitrum bridge portal: https://bridge.arbitrum.io/

2. Connect Your MetaMask Wallet:

Click on "Connect Wallet" on the top right corner of the screen. Select MetaMask from the dropdown list, and follow the prompts to connect your wallet.

3. Choose the 'L1 to L2' Deposit Option:

This denotes that you are moving assets from Layer 1 (Ethereum Mainnet) to Layer 2 (Arbitrum One Network).

4. Input Deposit Amount:

In the "Amount" field, enter the number of ETH you wish to bridge to Arbitrum. Ensure you have reserved some ETH for the gas fee on the Ethereum Mainnet.

5. Initiate the Deposit:

Click the "Deposit" button. A MetaMask transaction window will pop up, showing the transaction details and gas fee.

6. Confirm the Transaction:

After reviewing the transaction details, click "Confirm" in the MetaMask pop-up. This will initiate the transfer process.

7. Wait for Transaction Confirmation:

Bridging assets between Ethereum and Arbitrum can take a bit of time, largely because of Ethereum's block confirmation times. Remain patient and wait for the transaction to be confirmed. You can check the transaction status in your MetaMask activity or on Etherscan.

8. Verify Your Balance on Arbitrum:

Once the transaction is confirmed on Ethereum Mainnet, switch your MetaMask network to Arbitrum One. Check your ETH balance; it should reflect the amount you bridged minus any fees.


Bridging assets between Ethereum and other networks can seem daunting, especially for newcomers to the crypto space. However, with tools like MetaMask and clear user interfaces provided by platforms like Arbitrum, the process becomes relatively straightforward. Always ensure you are using official and trusted portals when bridging assets to avoid scams or loss of funds. Happy bridging!
