Arbitrum is an optimistic rollup-based Layer 2 network that is built on the Ethereum blockchain. It is designed to help scale the ETH network by taking the demand for computation and blockspace off the main chain and rolling it up to a Layer 2.

In this guide, we will walk you through step-by-step how to use the Arbitrum blockchain and how to add the Arbitrum network to your Metamask wallet.

How to add Arbitrum to Metamask

The Arbitrum network can be added to your Metamask account because it is an Ethereum Virtual Machine (EVM) compatible network. Metamask currently supports all Layer 1 and Layer 2 blockchains that are EVM-compatible and are written in the solidity programming language.

  1. Download the Metamask Wallet onto your Chrome or Mozilla browser.
  2. Click on your Metamask browser extension and select 'Add Networks'.

Does Arbitrum have a Token?

Arbitrum does not currently have a native token for their network. There is a lot of speculation that Arbitrum will airdrop a token to users of their Layer 2 platform in a similar fashion to what Optimism did in May of 2022.

If you want to get the Arbitrum airdrop, we recommend that you use the Arbitrum network and perform some trades on native decentralised exchanges like Uniswap and Sushiswap.
