February 27, 2025
By: Nemil Dalal (Head of CDP) & Tom Vieira (Head of Product, Base Builders)
TL;DR Coinbase Developer Platform (CDP) gives developers the tools they need to build and scale onchain. Today, we're simplifying scaling with Base Appchains. This launch lets builders achieve high throughput and low costs with dedicated blockspace—all in a few clicks. These high-speed Appchains offer customizable gas tokens, custom permissions, and seamless integration with CDP’s developer tools.
Scaling for high-traffic apps
Successful apps grow from small projects into high-traffic platforms, eventually requiring greater scalability and cost efficiency. This often leads to higher gas costs, congestion, and performance trade-offs.
To solve this, Coinbase Developer Platform is introducing Base Appchains—a dedicated, easy-to-deploy Layer 3 solution for teams needing a tailored scaling solution. With one-click deployment, pre-configured developer tooling, and seamless integration, Base Appchains make deploying dedicated blockspace simple. Now available on Base, Appchains are a powerful tool for any developer using CDP to scale their app.
Who should build on Base Appchains?
Base Appchains are designed for teams experiencing high engagement and transaction volume who need a scalable, cost-effective solution. Appchains provide dedicated blockspace while maintaining easy access to Base’s liquidity, developer tools, and broader ecosystem.
