Can I add Arbitrum to MetaMask?

Yes, the Arbitrum network can be added to a MetaMask Wallet because it is an Ethereum Virtual Machine compatible chain that supports solidity-based applications. To do so, To do so, you will need to add a custom RPC (Remote Procedure Call) URL for the Arbitrum network in MetaMask. As previously mentioned, these details can be easily obtained by visiting Chainlist.

What is Arbitrum One

The Arbitrum network is a layer 2 scaling solution for the Ethereum blockchain. It is designed to provide fast and low-cost transactions while maintaining the security of the Ethereum mainchain. The network is built on a technology called "Rollups" which allows for off-chain computation and on-chain verification.

Rollups are a type of layer 2 scaling solution that allows for the execution of smart contracts off-chain, which reduces the amount of data that needs to be stored on the Ethereum main chain. This leads to faster and cheaper transactions, as the off-chain computation can be done faster and at a lower cost than on-chain computation.

The Arbitrum network uses a unique approach to Rollups, it uses a combination of a virtual machine, called the "Arbitrum Virtual Machine" (AVM) and a "Rollup chain" to execute smart contracts. The AVM allows for the execution of smart contracts off-chain, while the Rollup chain ensures the security and integrity of the off-chain computations by providing a mechanism for on-chain verification.


Bottom Line

Arbitrum One is an innovative layer 2 scaling solution for the Ethereum blockchain that enables faster and more cost-effective transactions. By integrating the Arbitrum network with MetaMask, users can enjoy the benefits of this advanced technology seamlessly. The Chainlist App simplifies the process of adding Arbitrum One to MetaMask, allowing users to access and interact with the Arbitrum chain within minutes. With its unique approach to Rollups, the Arbitrum network holds great potential for the future of decentralized finance and blockchain technology.
