TL;DR

• Hyperlane brings permissionless cross-chain messaging to TON with on-chain Mailboxes, Relayers, and configurable security modules.
  
• Developers dispatch arbitrary data or token transfers via a TON-based Mailbox contract.
  
• Relayers pick up emitted events, deliver them to the destination Mailbox, and Interchain Security Modules (ISMs) verify their authenticity.
  
• Modular ISMs — Routing, Merkle-root multisig, legacy multisig, and Message-ID multisig — let you tailor your trust model.
  
• All smart contracts are upgradeable via timelocked multisig governance for continuous improvement.

Permissionless Architecture

Hyperlane is a fully permissionless protocol that lets any chain, whether L1, rollup or app chain, send arbitrary messages and assets to any other chain without centralized intermediaries. By design, Hyperlane enforces every operation through smart contracts, relayer nodes and transparent Interchain Security Modules.

System Overview

At a high level, Hyperlane on TON consists of:

• Mailbox Contracts on origin and destination chains for on-chain messaging interfaces.
  
• Relayers that poll origin Mailbox events and relay messages to destination Mailbox.
  
• Interchain Security Modules (ISMs) that verify authenticity before delivery.
  
• Message Recipient Contracts that handle delivered payloads.

Key Components

1. TON Mailbox: Stores dispatched messages and emits events for Relayers.
   
2. Relayer: Off-chain agents that watch for dispatch events and call destination Mailbox.
3. Interchain Security Modules (ISMs):
   
   1. Routing ISM: simple on-chain route check.
   2. Merkle-root multisig ISM.
   3. Legacy multisig ISM.
   4. Message-ID multisig ISM.
4. Message Recipient: Consumer contract that executes logic on delivered messages.‍
5. Governance & Upgrades: Upgradable via timelocked, N-of-M multisig to ensure safe evolution.

Message Dispatch Flow

1. Dispatch is called by Sender, which stores the message in the Origin Mailbox.
2. Mailbox emits a Dispatch event with metadata and payload.

Relayer & Delivery

3. Relayer picks up event, calls Destination Mailbox.
   
4. ISM verifies: proof-of-inclusion, multisig thresholds, Merkle roots, etc.
   
5. Recipient contract’s handle consumes the payload.

No single component can forge or block messages. Security is enforced by your chosen ISM.

Modular Security with ISMs

All Hyperlane contracts on TON are deployed as upgradable proxies. Validators (N-of-M multisig) control timelocked upgrades, ensuring you can patch bugs or improve features without hard forks.

Ecosystem Impact

By integrating Hyperlane on TON, developers can:

• Move tokens: build custom bridges via Warp Routes on TON.
  
• Execute interchain calls: power cross-chain DeFi, DAO governance, NFTs.
  
• Compose trust models: leverage Hyperlane ISMs to match your security needs.

Some Thoughts

Hyperlane on TON is more than a bridge. It is a permissionless messaging fabric connecting TON to the broader blockchain world. With on-chain Mailboxes, Relayers and configurable ISMs, RSquad delivers a robust, transparent and upgradeable interoperability layer.
