Hyperlane Protocol

The first permissionless interoperability layer enabling developers to build interchain applications with customizable security and seamless cross-chain communication.

What is Hyperlane?

Hyperlane is the first permissionless interoperability layer that allows smart contract developers to send arbitrary data between blockchains. Unlike traditional bridges, Hyperlane enables developers to build truly interchain applications with customizable security models.

Key Innovations:

  • Permissionless deployment to any blockchain
  • Modular security with Interchain Security Modules (ISMs)
  • Simple developer API through Mailbox contracts
  • Decentralized validator and relayer networks

How Hyperlane Works
Understanding the core components of Hyperlane's interchain messaging protocol

1. Dispatch

Application calls Mailbox.dispatch() to send a message to another chain

2. Validate

Validators attest to the message and provide cryptographic proof

3. Relay

Relayers deliver the message and proof to the destination chain

4. Process

Destination Mailbox verifies and delivers message to recipient
