How to Add Arbitrum to MetaMask

Can I Add Arbitrum to MetaMask?

‍Yes, Arbitrum is built to be compatible with Ethereum's Solidity programming language and can be smoothly integrated with MetaMask. This enables users to interact with applications on the Arbitrum network using their wallet, much like they would with the Ethereum mainnet. As a layer 2 scaling solution for Ethereum, it is safe, cost-efficient, and developer-friendly. It offers a cost-effective EVM environment, supports affordable transactions, and is supported by a robust community.

How to Add Arbitrum One to MetaMask

Connecting Arbitrum to a MetaMask wallet is seamless, thanks to the secure and trusted DeFi hub, ChainList. This platform is a blockchain data aggregator that offers an intuitive interface to locate and connect to any Web3 network, including the Arbitrum One chain plus hundreds of others.

Follow this short guide to integrate Arbitrum with MetaMask:

1. Open the ChainList application and input ‘Arbitrum' into the search bar.
2. From the results, identify the ‘Arbitrum One' box.
3. Click on the 'Connect Wallet' button within this box.

Arbitrum RPC Details

If you prefer to manually integrate the Arbitrum network to your MetaMask wallet instead of using ChainList, you can certainly do so by inputting the RPC details directly within the application. Below are the verified RPC details necessary to integrate the Arbitrum network into your MetaMask wallet:

• Network Name: Arbitrum One
• New RPC URL: https://arb1.arbitrum.io/rpc 
• Chain ID: 42161
• Symbol: ETH
• Block Explorer URL: https://arbiscan.io

What is Arbitrum One?

Arbitrum is a layer-2 scaling solution for Ethereum designed to improve the network's scalability and reduce transaction costs. It was built by Offchain Labs, a startup focused on developing technology to improve blockchain performance. Arbitrum uses a technology called Optimistic Rollups, which allows for a greater number of transactions to be processed off-chain while still maintaining the security guarantees of the underlying Ethereum network.

The primary goal of Arbitrum is to address the congestion and high gas fees that have become a significant issue for the Ethereum network, especially as it has grown in popularity. By enabling more transactions to be executed off-chain, Arbitrum aims to alleviate network congestion and lower transaction costs for users.

Final Thoughts

To sum up, Arbitrum, as a significant advancement in Layer 2 scaling solutions, enhances Ethereum's scalability and reduces concerns of congestion and high fees. Compatible with the Solidity programming language and easily integrated with MetaMask, it allows users seamless interaction with the Arbitrum network. Users can connect through ChainList or manually with RPC details.
