Hyperlane Protocol

Hyperlane is a permissionless interoperability protocol that enables seamless cross-chain communication for developers. Its unique design allows deployment across various blockchain environments, including layer 1 chains, rollups, and app-chains, without the need for approvals or intermediaries. This permissionless design empowers developers to build cross-chain applications with full control over their operations in a multi-chain ecosystem.

Architecture​

Hyperlane Messaging Flow

Basic Hyperlane cross-chain messaging flow1

Hyperlane's architecture consists of four key components:

  • Mailboxes: Core messaging contracts deployed on each chain that handle message sending/receiving
  • Interchain Security Modules (ISMs): Custom security logic that determines how messages are verified
  • Relayers: Off-chain agents that transport messages between chains
  • Validators: Fulfilling the security layer of the Hyperlane protocol

Fees​

Hyperlane fees are called Interchain Gas Payments and are payed by the message sender to the relayer.

For more info about the Interchain Gas Payments, consult the Hyperlane documentation
