hyperlane-cosmos

🌌 Why did we build hyperlane-cosmos?

• How come IBC gets to have all the Cosmos fun? This repo provides a reference implementation for integrating and maintaining Hyperlane modules in Cosmos blockchains.

🌌🌌 Who benefits from it?

Cosmos-SDK based chain builders and integrators looking to add hyperlane connectivity to their chain.

🌌🌌🌌 What does hyperlane-cosmos do?

This repository provides modules integrated into a reference chain to demonstrate mailboxes, isms, and other hyperlane features.

🌌🌌🌌🌌 How do I use it?

Getting Started

You will need go v1.19 or higher.

See go's documentation on how to download and install

Clone the repository

cd $HOME
git clone https://github.com/strangelove-ventures/hyperlane-cosmos
cd hyperlane-cosmos

Running Interchain Tests

To run interchain tests you will need to install Docker

Additionally, you will need heighliner to build the hyperlane-simd image.

Install Heighliner

To build the hyperlane-simd image for interchain test you will need heighliner:

cd $HOME
git clone https://github.com/strangelove-ventures/heighliner
cd heighliner
go install ./...

Build the hyperlane-simd image:

From within the hyperlane-cosmos directory, heighliner can build a hyperlane-simd:local image:

cd $HOME/hyperlane-cosmos
heighliner build --chain hyperlane-simd --local

Run tests

From within the hyperlane-cosmos directory, the unit tests and interchain tests may be executed:

cd $HOME/hyperlane-cosmos
make test

Roadmap

• Build hyperlane-cosmos to serve as the collaboration space for developing the modules.
• include a module integration guide for chain maintainers to be able to introduce hyperlane into their chain.
