Omni Hello World Template

This repository serves as a template for Ethereum smart contract development using Foundry, specifically designed for projects intending to utilize the Omni protocol for cross-chain interactions. The template features the Greeter and GreetingBook contracts as examples to demonstrate how contracts can interact across different blockchain networks.

Installation

To use this template for your project, initialize a new project either by using forge init or cloning this repo::

forge init --template https://github.com/omni-network/hello-world-template.git

git clone --recursive https://github.com/omni-network/hello-world-template.git
git submodule update --init --recursive

Usage

1. Run make build to build the smart contracts.
2. Run make test to run tests.

If you want to deploy the contracts agains a local devnet:

1. Run make ensure-deps to ensure you've installed the omni cli.
2. Run make devnet-start to deploy a local instance of Omni, which includes local deployments of Omni, Arbitrum, and Optimism.
3. Run make deploy to deploy your smart contracts.

Note: you'll need to have docker installed to run the local devnet.

When finished, you can run:

make devnet-clean
