About Caldera
Caldera is a next-generation platform designed to power the creation and deployment of scalable, interconnected application-specific blockchains. With over 75+ custom rollups, 550M+ transactions, and $1B+ in total value locked (TVL), Caldera is one of the fastest-growing modular blockchain ecosystems in the world. At its core, the platform aims to unlock seamless scaling for massive Web3 applications through its customizable Rollup Engine and its powerful interoperability layer, Metalayer.
What sets Caldera apart is its holistic infrastructure: developers can spin up dedicated rollups tailored to specific use cases while remaining securely anchored to Ethereum and other L1s. The platform supports advanced onchain sectors including gaming, AI, and DeFi by providing modular toolkits, zero-fee execution environments, and cross-chain liquidity access. Whether it’s powering frictionless gameplay or enabling KYC-verified DeFi exchanges, Caldera’s architecture empowers teams to go from prototype to production with unprecedented scalability and interoperability.
Caldera is a modular blockchain infrastructure platform that empowers developers to launch and operate their own high-performance rollups. As a true enabler of the multi-chain vision, Caldera allows applications to build custom, app-specific chains that are interoperable, scalable, and anchored to Ethereum for settlement. With over 75 rollups deployed, more than $1 billion in total value locked (TVL), and 17 million unique wallets onboarded, Caldera is one of the most successful modular blockchain platforms in operation.
At the heart of Caldera’s offering is the Rollup Engine—a developer-first framework for launching chains tailored to the specific needs of apps and communities. Whether the requirement is sub-second finality, low gas fees, or zero-fee transactions, developers can configure the environment to meet their needs without sacrificing performance or decentralization. This makes Caldera ideal for massive-scale blockchain games, AI computation platforms, and DeFi protocols seeking composability and horizontal scalability.
What truly distinguishes Caldera is the Metalayer—its proprietary interoperability and messaging infrastructure. The Metalayer is built to provide seamless cross-chain connectivity using a Hyperlane-powered message-passing protocol that supports both 1-to-1 writes and many-to-1 cross-chain reads. With Metalayer, Caldera rollups gain instant access to a broader liquidity ecosystem and unlock composable interactions across chains like Ethereum, Arbitrum, Base, zkSync Era, and Optimism.
A standout feature of the Metalayer is the Intents Engine, which enables declarative cross-chain execution. Instead of manually orchestrating transactions across different environments, developers define high-level "intents" and let the infrastructure manage execution, security, and finality. The Metalayer also supports configurable finality modes, giving developers the choice between fast confirmation (~10s) or more secure “finalized” settlement anchored on the parent chain. This level of flexibility is crucial for apps that require different tradeoffs between speed and trust.
Caldera’s ecosystem supports use cases across:
- Gaming – Rollups offer zero-fee gameplay and instant asset transfers, enabling developers to craft seamless in-game economies.
- AI – Provides plug-and-play infrastructure to support decentralized machine learning and compute-heavy applications.
- DeFi – Modular exchanges can be built with access to cross-chain liquidity and tools like KYC enforcement via Metalayer integrations.
In the modular blockchain space, Caldera competes with platforms like:
- Polygon CDK – A modular framework for launching Layer 2 chains using zkEVM.
- Rollkit – A modular rollup framework that integrates with Cosmos SDK and Celestia DA.
- Fuel – A high-throughput rollup platform built with a parallelizable execution layer.
Ultimately, Caldera positions itself as the “internet of chains”—a horizontally scalable network of application-specific blockchains connected via the Metalayer. It offers builders everything needed to create performant, composable, and user-friendly Web3 apps. Developers interested in launching their own chain or exploring interoperability through Metalayer can get started via the official Caldera website.

Caldera FAQ
Caldera’s Rollup Engine enables developers to launch custom blockchains tailored to their app’s needs, optimizing for performance, gas models, latency, or compliance. This provides a more scalable and flexible environment compared to general-purpose Layer 1s. Developers can build rollups that match the complexity and scale of their product, from high-speed games to compute-heavy AI dApps. Learn more at caldera.xyz.
Metalayer isn’t just a bridge—it’s a comprehensive interoperability framework for rollups. It includes a message-passing protocol, intents execution engine, and cross-chain state reads, all powered by Hyperlane. This allows developers to build dApps that work across chains without needing separate infrastructure for each connection. Visit caldera.xyz to explore the architecture.
Yes, Caldera supports compliant DeFi ecosystems via the Metalayer. Developers can integrate KYC, AML, and jurisdictional controls into their rollup logic while accessing shared liquidity across chains. This makes Caldera a powerful option for building enterprise-grade financial protocols that require regulation-aware functionality. Learn more at caldera.xyz.
Intents-based execution allows developers to define high-level outcomes instead of manually orchestrating multi-chain actions. Caldera’s Metalayer handles the routing, settlement, and communication, reducing complexity and developer overhead. This approach improves UX, reduces failure points, and makes cross-chain dApps faster and safer to build. Discover more at caldera.xyz.
The Metalayer is live across all Caldera rollups and is also deployed on major L2s including Ethereum, Arbitrum, Base, zkSync Era, and Optimism. As new interoperability standards emerge, Metalayer will automatically upgrade to support them—making it a future-proof choice for cross-chain builders. See supported networks on caldera.xyz.
