BuildGameson Base

Base is a secure, low-cost, developer-friendly Ethereum L2 built to bring the next billion users to web3.

Making Ethereum

accessible to everyone

Secured by Ethereum

Base is built with the security and scalability you need to power your dapps. It leverages the underlying security of Ethereum and lets you confidently onramp into Base from Coinbase, Ethereum L1, and other interoperable chains.

Big features,

small fees

Get the EVM environment at a fraction of the cost. Get early access to Ethereum features like Account Abstraction (ERC4337), simple developer APIs for gasless transactions, and smart contract wallets.

Open Source,

powered by Optimism

Base is built on Optimism’s open-source OP Stack. We’re joining as the second Core Dev team working on the OP Stack to ensure it’s a public good available to everyone; and contributing a portion of sequencer revenue to funding public goods.

Scaled by Coinbase

Base is the easiest way for decentralized apps to leverage Coinbase’s products and distribution. Seamless Coinbase integrations, easy fiat onramps, and access to the $130B assets on platform in the Coinbase ecosystem.

The best of

Ethereum but

10x cheaper

No code changes needed. Base is EVM equivalent, so all of your code, tools, and infrastructure work out of the box. Base’s rollup architecture reduces costs by 10x for users.

Base is built to be the onchain home for Coinbase products, users, and assets, as well as an open ecosystem where anyone can build for them. Leverage Coinbase’s developer tools to make building easy and reach Coinbase users.

Optimism Base graphic

Base is powered by Optimism's OP Stack, making it one of the most secure, scalable EVM L2s out there. The OP Stack is an open-source public good that will serve as the foundation for a “superchain” of L2s that share interoperability, sequencing, and governance.

Coinbase Base graphic

Base is incubated within Coinbase and plans to progressively decentralize in the years ahead. We believe that decentralization is critical to creating an open, global cryptoeconomy that is accessible to everyone.

Base is our commitment to onchain

We believe that the onchain platform is the most important developer platform since the internet (“online”). We believe that the onchain platform should be open source, free to use, and globally available. And we believe that in order to make it really work, we need all hands on deck, working together to scale in a secure, decentralized, easy-to-use way.
