Coinbase has opened its Base mainnet to builders, marking a significant step in the company's on-chain strategy. The network, which is aligned with Optimism's Superchain architecture, is now live for developers to start building decentralized applications. The move comes as Coinbase pushes deeper into blockchain infrastructure, aiming to bring more users and assets on-chain.
What Base is and why it matters
Base is a Layer 2 blockchain built on Ethereum, designed to offer faster and cheaper transactions while maintaining Ethereum's security. By opening the mainnet to builders, Coinbase is inviting developers to deploy smart contracts and launch dApps on the network. The company has positioned Base as a key piece of its broader on-chain strategy, which includes integrating crypto into everyday financial services. According to a blog post from Coinbase, the mainnet launch is a milestone in making on-chain applications more accessible.
The Optimism Superchain connection
Base is built using the OP Stack, the same technology that powers Optimism. This alignment means Base is part of the Superchain ecosystem, a network of interoperable Layer 2 chains that share security and communication standards. By joining the Superchain, Base can benefit from shared infrastructure and a growing ecosystem of developers. The blog post emphasized that this collaboration allows Base to focus on user experience while leveraging Optimism's proven technology.
What builders can expect
Developers can now deploy on Base using familiar Ethereum tooling, such as Solidity and the Ethereum Virtual Machine. The mainnet supports a range of applications, from DeFi protocols to NFTs and gaming. Coinbase has also provided documentation and resources to help builders get started. The company has not yet announced a public mainnet launch for end users, but the builder phase is a critical step before wider release. Builders are encouraged to test and iterate on the network, with the promise of future incentives and support.
Coinbase's broader on-chain push
The launch of Base is part of Coinbase's strategy to become more than just a centralized exchange. The company has been investing in on-chain products, including its wallet and NFT marketplace. By building its own Layer 2, Coinbase can offer lower fees and faster transactions for its users while maintaining control over the user experience. The blog post noted that Base is designed to be decentralized over time, with plans to eventually hand over control to a community of token holders. For now, the focus is on attracting builders and growing the ecosystem.
The Base mainnet is now open for builders. The next milestone will be a public mainnet launch, though Coinbase has not set a specific date. Developers interested in building on Base can find documentation on the official website.
