Hyperlane is an interchain messaging protocol. Apps dispatch messages via the Mailbox on the origin chain; relayers index and deliver them to the destination chain. The stack includes Solidity core contracts (Mailbox, ISMs, hooks, Warp token routes), a TypeScript SDK and CLI, and Rust relayer/validator agents.
