Cross-chain interoperability framework for rollups

Welcome

Caldera Metalayer Documentation

Concepts

The Metalayer contains an end-to-end intents execution engine that enables fast asset onboarding and declarative cross-chain execution for rollups.

Overview and Architecture

Aggregation Layer

The settlement layer provides secure finality for cross-chain messages and intent execution in the Metalayer ecosystem.

Settlement Layer

The Metalayer is designed to power settlement for intents-based protocols. We’re starting with bridging use cases, but plan to onboard a wider set of these protocols over time.

Overview

Metalayer allows developers to send arbitrary messages between chains. This is useful for intent settlement, contract coordination, governance execution, and multi-chain applications.

Message Passing (Writes)

Cross-Chain Reads

Integration

Integration Requirements

Protocol developers should utilize these interfaces to send cross-chain messages and initiate cross-chain reads via the Metalayer.

Contract Interfaces

Protocol developers should use these addresses on Testnet

Testnet Addresses

MetaRouter TypeScript SDK for cross-chain token bridging.
