How to Use Arbitrum Bridge With MetaMask

How to Bridge to Arbitrum Using MetaMask

Bridging in DeFi is the process of transferring your assets over from one blockchain to another. When you interact with a bridge, you’re not actually moving the token over but rather swapping it for the equivalent token on the new chain.

Bridging allows you to use existing funds that you have on a different chain without needing to buy new assets from a centralized exchange and withdrawing them to the new chain.

TLDR; The 4 steps of bridging to Arbitrum

  1. Add Arbitrum Network to MetaMask
  2. Open Arbitrum bridge and select desired network to send from
  3. Deposit asset into the bridge and wait for it to send
  4. Switch back to Arbitrum and use funds

You’ll need one of these tokens on your starting chain (i.e. Ethereum) in order to move funds over to Arbitrum.

Before we begin bridging, ensure you have MetaMask installed and ready to go. You can use another compatible wallet, such as Rainbow, Coinbase Wallet, or Trust Wallet, if you have funds on there already. The process will not be exactly the same but should be easy enough to still follow along.

If you don’t have MetaMask installed, then check out our MetaMask installation guide to get up and running.

Alright, let’s get bridging!

Step 1: Add Arbitrum Network to MetaMask

Step 2: Open Arbitrum Bridge and Choose Ethereum Network

For this example, we’re going to use Arbitrum’s native bridge platform ( to send our tokens from Ethereum to Arbitrum.

Optimism’s native bridge currently only supports the Ethereum Mainnet and it’s older Aribtrum Nova chain, so if you’re looking to swap from another chain (i.e. Polygon or Optimism) then you can use a third-party bridge like Across.

Now, switch back to Ethereum Network in your MetaMask wallet and Open the Arbitrum Bridge platform.

Connect your wallet to the application and make sure Ethereum Mainnet has been selected.

Step 3: Deposit ETH into Bridge

Enter the amount of ETH (or equivalent token) you’d like to Bridge over to Arbitrum and click Move funds to Arbitrum One.

Enter ETH amount Arbitrum bridge
Enter ETH amount to send

From here you can see the amount you’ll be moving as well how much you’ll need to pay in gas fees for the transfer.

Confirm the transaction in you wallet and wait for the transaction to go through. This should take around 15 minutes.

Step 4: Switch back to Arbitrum

Switch back to the Arbitrum Network in MetaMask, and you should see that your bridged tokens are now available to use.

If you cannot see your tokens, it may be because you haven’t imported them to MetaMask. To do so, click on Import tokens and add the token contract address associated with that token.
