Overview
Base is Coinbase's Ethereum Layer 2 built on the OP Stack, offering low-cost transactions and easy onboarding for mainstream users. Launched in August 2023, it connects Coinbase's large user base directly to on-chain applications. Its native chain has no token of its own, positioning it as a gateway rather than an investment vehicle.
How It Works
Base runs as an optimistic rollup using the OP Stack, posting transaction data to Ethereum and inheriting its security. Coinbase provides sequencer infrastructure, while the network's development and governance are designed to become progressively more decentralized. Users bridge funds through Coinbase or the standard L2 bridge, and developers deploy EVM-compatible contracts with minimal changes.
Why It Matters
Base is significant for mainstream adoption because of its distribution: Coinbase's millions of users can enter on-chain applications with a few clicks. Its association with the Superchain ecosystem means it shares tooling and interoperability with other OP Stack chains. Its reliance on Coinbase-operated sequencing, however, is a centralization consideration to weigh against its convenience.
