About Base

Base is an open-source optimistic rollup built on the Ethereum blockchain. Rollups are L2 blockchains built to help layer one (L1) blockchains like Ethereum scale. They bundle hundreds of transactions and submit them to L1 as a single transaction, which reduces gas fees for the end user.

About Arbitrum

Arbitrum is a decentralized L2 blockchain that aims to provide high performance and low transaction fees. Arbitrum has the potential to offer significant benefits to developers and users of decentralized applications, particularly in terms of scalability and cost-effectiveness.
