Ethereum <> Arbitrum

In this document, we will explain how to bridge between Ethereum Mainnet and Arbitrum.You can also skip this tutorial and go directly to https://bridge.arbitrum.io to bridge

Preparation Phase

For bridging, the chains you will bridge in your wallet must be set up. In EVM-based wallets (such as Metamask), Ethereum is already set up by default. If you don't have the Arbitrum network in your wallet, you need to set it up first.

Phase 1

Add Arbitrum to MetaMask Manually

• Open the drop-down menu by clicking on the Ethereum Mainnet display. Then click “Add network”.

• Now click on “Add a network manually”.

• On the “Add a network manually” page that opens, you'll need to add the following details. Click “Save” when you're done.

  • Network Name: Arbitrum One

  • New RPC URL: https://arb1.arbitrum.io/rpc

  • Chain ID:42161

  • Currency Symbol: ETH

  • Block Explorer URL: https://arbiscan.io/

Or you can use ChainList to add new network. By visiting the link below, you can automatically add the "Arbitrum One" network to your wallet.

Phase 2

You need to have the contract addresses of the tokens you want to bridge. The Ethereum and Arbitrum contract addresses for EQB is as follows:

Ethereum Mainnet:

EQB: 0xfE80D611c6403f70e5B1b9B722D2B3510B740B2B

Arbitrum:

EQB: 0xBfbCFe8873fE28Dfa25f1099282b088D52bbAD9C

Once you have added the chains and tokens to your wallet, your wallet should look like this for the Ethereum and Arbitrum One networks:

Bridging from Ethereum Mainnet to Arbitrum

In this phase, we will bridge the EQB token from Ethereum Mainnet to Arbitrum.

Step 1 - Switch to the Ethereum network in your wallet. Please go to https://bridge.arbitrum.io and connect with your wallet.

Step 2 - Select Mainnet on the "From" section.

Step 3 - Paste the EQB (Ethereum) contract address that we shared above into the token search box.

Step 4 - Select Arbitrum One on the "To" section.

Your transaction will appear like this before confirmation:

Step 5 - Then click on the "Move funds to Arbitrum One" button and confirm the transaction in your wallet.

Review the notifications that appear and confirm them one by one.

Step 6 - Grant the token spending permission for the Arbitrum bridge. Here, you can choose "Use default" to grant unlimited spending approval, which can provide convenience for future transactions.

Step 7 - After granting the spending permission, you will see a new notification in your wallet to confirm the bridging transaction. You can proceed with this confirmation to initiate the bridging process.

Step 8 - Once you confirm this transaction, the bridging process will begin. As shown in the image below, the process will take approximately 15 minutes.

Step 9 - When the bridging process is completed, you will see a message similar to the one below.

Now you have successfully transferred the EQB token from Ethereum to the Arbitrum network, and you can switch to the Arbitrum network in your wallet to see the EQB token.
