# Migrating to Arbitrum ## Setting up your wallet {% hint style="info" %} This guide assumes that you already know how to use the MetaMask extension wallet and have this wallet funded with Eth. If this is new to you, please see this helpful guide for setting up and funding your wallet: [Getting Started with MetaMask](https://metamask.zendesk.com/hc/en-us/articles/360015489531-Getting-started-with-MetaMask) {% endhint %} ### Add Arbitrum to MetaMask Our website should prompt you to add Arbitrum as a Network to your MetaMask extension when you arrive. If for some reason that didn't work, you can add it manually: 1. Click on the MetaMask extension 2. Click on “Ethereum Mainnet” network at the top -> click on “Add Network” at the bottom of the menu, and enter the following in the tab that appears: **Network Name:** Arbitrum\ **RPC:** **Chain ID:** 42161\ **Currency Symbol:** ETH\ **Block Explorer URL:** ### Bridge Eth to the Arbitrum Network {% hint style="info" %} Bridge more Eth than will be necessary to do what you want so that you can also pay for transaction (gas) costs. On average, gas fees on Arbitrum are between 0.0001 and 0.0008 Eth. For example, if you're planning on summoning a Seeker for 0.05 Eth, bridge up 0.06 Eth to cover gas fees. {% endhint %} By "bridging" assets, you are moving them between blockchain networks (likely from Ethereum Mainnet to Arbitrum). The official Arbitrum Bridge can be found here: [Arbitrum Bridge](https://bridge.arbitrum.io/) If you need help bridging, please follow along with their tutorial: [Arbitrum Bridge Tutorial](https://arbitrum.io/bridge-tutorial/) ### You're ready! After waiting the requisite time for your assets to bridge (as of writing, 10 minutes), you should see that you have an Ether balance on the Arbitrum network within MetaMask.
