Omni Contracts

Overview

This directory contains the smart contracts and related tooling for Omni. It is structured to facilitate development, testing, and deployment of the contracts.

Contents

  • bindings/: Go bindings for contracts, including utility scripts for generation.
  • src/: Solidity source files, organized by functionality (deploy, examples, interfaces, libraries, protocol).
  • script/: Scripts for deploying contracts on various networks and utility tasks.
  • test/: Test cases for the smart contracts, using Foundry.
  • Makefile: Utility to automate common tasks such as building contracts, generating bindings, and running tests.
  • foundry.toml, package.json, pnpm-lock.yaml, tsconfig.json: Configuration files for Foundry, Node.js, and TypeScript.

Installation

To set up your environment for development:

  1. Install Foundry for smart contract compilation and testing. Follow the instructions at Foundry's GitHub repository.
  2. Install Node.js and pnpm to handle script execution and package management:
  3. Ensure you have abigen installed for generating Go bindings. It should be version 1.13.14-stable. Install with: 
    go install github.com/ethereum/go-ethereum/cmd/abigen@v1.13.14

Build

To compile the smart contracts, run:

make build

This command compiles the Solidity contracts and also prints version information of the tools used.

Running Tests

Execute the test suite with:

pnpm run test

AVS Tests

Local

Or, for AVS tests locally with a running anvil node:

make avs-fork-test-local

Note: checks require setting an INFURA_KEY and ETHERSCAN_GOERLI_KEY, however these may be set to dummy values for local testing.

Goerli

Or, for AVS tests with on a goerli fork:

make avs-fork-test-goerli

Generating Bindings

Generate Go bindings for the contracts with:

make bindings

This command requires abigen and will generate bindings, including examples.

Deployments

Deploy contracts to networks such as Goerli with scripts included in the script/ directory. Use the following commands for deployment and verification:

  • Deploy to Goerli: 
    make deploy-goerli-avs
  • Verify contracts on Goerli Etherscan: 
    make verify-goerli-avs
