Base

Base is an open-source optimistic rollup built on the Ethereum blockchain. Rollups are L2 blockchains designed to enhance the scalability of layer one (L1) blockchains like Bitcoin and Ethereum. By bundling hundreds of transactions and submitting them to L1 as a single transaction, rollups significantly reduce gas fees for the end user. Base was pioneered by Coinbase using Optimism’s OP stack, marking it as the second L2 deployed on the OP Stack after the Optimism Mainnet. Its EVM compatibility ensures that developers can effortlessly deploy their EVM codebase from Ethereum and other compatible chains directly to Base. For a deeper understanding of the specific methods for Base, refer to their official documentation.
