Cross chain messaging with Hyperlane

Who this is for: developers who need to pass messages or assets between Lumia and a chain outside the Polygon CDK/AggLayer ecosystem. You should already know: Interoperability.

How Lumia reaches other chains

Lumia's documented route to chains outside the Polygon CDK/AggLayer ecosystem is Hyperlane, a permissionless interchain-messaging protocol: any chain can connect to it without needing prior approval from a central operator, and it lets a contract on one chain send a message that a contract on another chain can verify and act on. It's a general-purpose messaging layer, not specific to any one chain family, which is why it's the tool documented for this role. What Lumia gets inside that ecosystem instead is covered under Lumia's chain framework and settlement.
