What is the Metalayer?

Welcome to the Metalayer, Caldera’s cutting-edge cross-chain interoperability framework. Designed to revolutionize how rollups interact with other chains, the Metalayer provides a seamless, secure, and efficient platform for cross-chain operations.

Intents Engine

An end to end intents execution engine.

Message Passing

A secure Hyperlane-based message-passing protocol supporting 1-to-1 message passing and many-to-1 reads.

​
Key Features

  • Intents Engine: At the heart of the Metalayer is the powerful intents engine, which allows developers to define high-level intents for cross-chain execution. This engine simplifies complex operations, enabling fast asset onboarding and declarative execution across multiple chains.

  • Message Passing Protocol: Built on Hyperlane, the Metalayer’s message-passing protocol supports both 1-to-1 message passing and many-to-1 reads. This ensures reliable and secure communication between chains, facilitating a wide range of cross-chain applications.

  • Security and Composability: The Metalayer is designed with robust security protocols and composability in mind, allowing developers to build secure and flexible applications that can easily integrate with existing blockchain ecosystems.

​
Deployment and Availability

The Metalayer is available on all Caldera chains, providing out-of-the-box interoperability. Additionally, it is deployed on major networks such as Ethereum, Arbitrum One, Base, zkSync Era, and Optimism. Our collaborations with leading protocols like Eco, Across, Relay, and Hyperlane ensure that the Metalayer is equipped with the best tools and technologies for cross-chain interactions.
