# Metalayer Docs

## Docs

- [Welcome to the Metalayer](https://docs.caldera.xyz/metalayer/about-the-metalayer.md): Metalayer is Caldera's cross-chain interoperability framework, enabling fast asset onboarding and cross-chain execution for rollups.
- [Contract Interfaces](https://docs.caldera.xyz/metalayer/developers/cross-chain-dapps/contract-interfaces.md): Protocol developers should utilize these interfaces to send cross-chain messages and initiate cross-chain reads via the Metalayer.
- [Integrating with the Metalayer](https://docs.caldera.xyz/metalayer/developers/cross-chain-dapps/overview.md): Protocol developers can utilize the Metalayer to send cross-chain messages and initiate cross-chain reads.
- [Testnet Addresses](https://docs.caldera.xyz/metalayer/developers/cross-chain-dapps/testnet-addresses.md): Protocol developers should use these addresses on Testnet
- [Typescript SDK](https://docs.caldera.xyz/metalayer/developers/token-bridging/typescript-sdk.md): Comprehensive guide to using the MetaRouter TypeScript SDK for cross-chain token bridging.
- [Aggregation Layer](https://docs.caldera.xyz/metalayer/intents/aggregation.md)
- [Overview and Architecture](https://docs.caldera.xyz/metalayer/intents/overview.md): The Metalayer contains an end-to-end intents execution engine that enables fast asset onboarding and declarative cross-chain execution for rollups.
- [Settlement Layer](https://docs.caldera.xyz/metalayer/intents/settlement-layer.md): The settlement layer provides secure finality for cross-chain messages and intent execution in the Metalayer ecosystem.
- [null](https://docs.caldera.xyz/metalayer/intents/third-party-bridges.md)
- [Message Passing (Writes)](https://docs.caldera.xyz/metalayer/message-passing/cross-chain-calls.md): Metalayer allows developers to send arbitrary messages between chains. This is useful for intent settlement, contract coordination, governance execution, and multi-chain applications.
- [Overview](https://docs.caldera.xyz/metalayer/message-passing/overview.md): 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.
