How To Bridge Assets From Ethereum To Arbitrum

Learn how to bridge your assets from L1 to L2 with the leading cross-chain protocol.

Layer 2 networks such as Arbitrum continue to see an impressive rise in metrics across the board. Whether we measure developer activity and new protocols being launched, user wallet growth or plain and simple TVL – there’s no doubt that adoption is increasing at a rapid pace.

With lower transaction fees and higher throughput, it appears that for now, scaling solutions are definitely here to stay. And so naturally, you might be looking for the best way to move your funds over from mainnet. We’ve broken down the steps you need to take to move your assets such as ETH, USDC, and USDT over from Ethereum to Arbitrum in a timely and safe manner.

Short on time? Follow these 5 steps to bridge from ETH to Arbitrum

  1. Head over to Synapse Protocol and connect your wallet.
  2. Select Ethereum as ‘From’ (current chain) and Arbitrum as ‘To’ (destination chain).
  3. Choose the asset you would like to bridge across (ETH, USDC, SYN etc).
  4. Enter the amount you would like to transfer over to Arbitrum.
  5. Select ‘Bridge Token’ and then sign the transaction. Transfers typically take a minute or two to complete.

Adding the Arbitrum Network to MetaMask

Before bridging over it’s helpful to already have Arbitrum added as a network. If you have completed this step, you can skip ahead to the next section!

To add the Arbitrum network, open MetaMask and select “Ethereum Main Network” at the top (as seen below).

Then select “Add Network”.

Finally, enter the following network information:

Network Name: Arbitrum
Chain ID: 42161
Currency Symbol: ETH
Block Explorer URL:

You’ll now be successfully connected to the Arbitrum network.

About Arbitrum

Arbitrum is the first scaling solution to launch on Ethereum. The network has currently processed over 21 million transactions to date and boasts a TPS of 1.3 seconds. While Arbitrum relies on the robustness of Ethereum’s security model, it’s utility derives from the fact that it can ‘roll up’ many transactions into one and then submit them back to Ethereum. This quick transaction speed and low cost is a huge advantage for helping Ethereum to continue to scale.

In addition, Arbitrum is also EVM compatible meaning that developers can easily move their existing applications and protocols over to Arbitrum without needing to make any major changes.
