In this article, I will explain the process of how to add Arbitrum to MetaMask Wallet, step by step. Arbitrum is an Ethereum Layer 2 solution with faster and cheaper transactions.
Once added, you will have access to Arbitrum dApps in MetaMask, and you will be able to manage your Arbitrum tokens in the wallet and improve your overall cryptocurrency experience, all in one place.
What is Arbitrum?
Arbitrum is an Ethereum Layer 2 solution for speed, cost, and scalability improvements. Most of the transactions are processed off-chain, and built on Ethereum security as decentralization. It uses Optimistic Rollups technology, which takes several transactions, processes them as one, and sends them to the Ethereum mainnet.
This significantly reduces gas fees and solves congestion issues. All Ethereum smart contracts and tokens are Arbitrum compatible, and therefore all dApps, DeFi, and NFT platforms are compatible and extend. The security and reliability of Ethereum mean that the increasing trimmed cost experience is easier in Arbitrum’s trimmed cost experience ecosystem.
