Before you choose

Requirements & limits

The repository is public and lists an Apache-2.0 license.

  • The README identifies the main branch as v3 and says v2 is deprecated in favor of v3.
  • The monorepo uses pnpm workspaces and targets Node.js 24.
  • Repository contributor prerequisites include Foundry, jq, gitleaks and typos.
  • The project information here does not specify supported networks or exact deployment and runtime environments.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Prepare the Hyperlane monorepo development environment

Install the documented tools and workspace dependencies for working on the Hyperlane v3 monorepo.

Before you start

  • A local copy of the repository.
  • Node.js version 24 and pnpm.
  • jq, gitleaks, and typos.
  • Foundry and its foundryup installer.

Steps

  1. Install jq, gitleaks, and typos using their official installation options; the README gives brew install typos-cli or the command below for typos.

    Documented command
    cargo install typos-cli --locked

  2. Install nvm if needed, then run nvm install 24 and nvm use 24. The repository’s .nvmrc is intended to switch versions automatically.

  3. Install foundryup with the command below, then install the pinned Foundry toolchain with foundryup --install $(cat solidity/.foundryrc).

    Documented command
    curl -L https://foundry.paradigm.xyz | bash

  4. From the repository root, install workspace dependencies with pnpm install.

Expected outcome

The documented prerequisite tools and pnpm workspace dependencies are installed for monorepo work.

Guide limitations

  • The README identifies these steps as preparation for working on the monorepo; it does not document a complete application integration, deployment, or runtime procedure.
  • The repository targets Node.js 24.
