Welcome to our walkthrough on using Hyperlane, an innovative interchain messaging protocol that enhances communication between blockchains. In this guide, you’ll learn how to set up your environment, work with dependencies, and much more!

What is Hyperlane?

Hyperlane allows developers to build interchain applications that communicate seamlessly across different blockchains, maintaining shared states. It’s like building a bridge connecting two islands (blockchains), allowing everyday transactions to flow smoothly between them.

Prerequisites for Using Hyperlane

Before diving into Hyperlane, ensure your environment is properly set up by following these steps:

1. Install jq

• jq is a command-line JSON processor. You can download it from the official page or use your preferred package manager.

2. Install Foundry

• First, ensure you have Foundry installed. Run the following command to install it:

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

• Then, run the command below to install its components:

foundryup

• For further details, refer to the Foundry Book.

3. Install Node

• This repository targets Node version 20. We recommend using nvm for version management.
• To install nvm, run:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash

• Now, install version 20:

nvm install 20
nvm use 20

• You can manage versions automatically using the .nvmrc file.

4. Setting Up Workspaces

• This monorepo utilizes Yarn Workspaces for managing dependencies.
• To install dependencies, build, and run commands across all packages, execute the following from the root directory:

yarn install
yarn build

• For VSCode users, launch the multi-root workspace with:

code mono.code-workspace

5. Logging

The TypeScript tooling employs Pino for structured JSON logging. You can configure the verbosity and the output format with environment variables:

LOG_LEVEL=DEBUG
LOG_FORMAT=PRETTY

Releasing Packages and Managing Versions

Releasing your work is an important step. Here’s how to do it:

1. Using Release Agents

• Tag the commit with the current date in the format agents-yyyy-mm-dd, e.g., agents-2023-03-28.
• Create a Github Release with a changelog against the previous version, titled “Agents MMMM DD, YYYY”.
• Include the agent docker image tag in your release description and summarize change highlights.

2. Releasing to NPM

• Utilize changesets for NPM releases. Use the release script in package.json to publish.
• For alpha or beta versions, follow the directions here.

Troubleshooting

If you encounter issues while working with Hyperlane, consider these troubleshooting tips:

• Ensure that all dependencies are up-to-date and properly installed.
• Check your Node version compatibility.
• Review your logging for any errors reported by Pino.
• If problems persist, consult the documentation for additional guidance.
