About Base Mainnet

        
Base is an Ethereum Layer 2 designed for lower transaction costs and faster confirmation times while preserving access to the broader Ethereum ecosystem. It is a practical option for consumer apps and high-frequency onchain interactions.

        

          Built as an optimistic rollup, it publishes data to Ethereum for final settlement.
          Commonly used for social, payments, and app experiences that need low-fee UX.
