What is Base?

Base is a secure, affordable, and developer-friendly Ethereum L2 designed to bring the next billion users to web3. Incubated within Coinbase and planning progressive decentralization, Base aims to create an open, global crypto economy accessible to all.

Secured by Ethereum, Base offers the security and scalability needed for decentralized apps, allowing easy asset onboarding and security from L1 and interaction with other L2 chains. The project provides a cost-efficient EVM environment and early access to Ethereum features.

The project streamlines integration with Coinbase products and distribution for decentralized apps, offering seamless integrations, easy fiat onramps, and access to a vast user base and assets within the Coinbase ecosystem.

Blockchain was originally built on open source code and developed in collaboration with Optimism. In February 2026, Coinbase (Base) announced its transition from OP Stack to its own stack. This is not a complete abandonment, but rather a strategic shift to accelerate updates and simplify operations.
