Arbitrum is a layer 2 solution for Ethereum dApps. The existing Ethereum (layer 1) network is plagued by high gas fees. With Arbitrum, that problem can soon be made history. Arbitrum is also scalable, allowing users to use their favorite tools in the DeFi space.
Like Ethereum, Polygon, Binance Smart Chain, and Avalanche, you can add Arbitrum to your Metamask Wallet. This will allow you to connect to decentralized platforms like Sushiswap where you can use Arbitrum’s network for exchanging crypto.
