An EigenLayer AVS 🌐

A simple Hello World AVS for EigenLayer with the BLS-based Contract Configuration

📚 Prerequisites

Before you can run this project, you will need to have the following software installed on your machine:

• Rust
• Forge

You will also need to install cargo-tangle, our CLI tool for creating and deploying Blueprints:

To install the Tangle CLI, run the following command:

Supported on Linux, MacOS, and Windows (WSL2)

curl --proto '=https' --tlsv1.2 -LsSf https://github.com/tangle-network/gadget/releases/download/cargo-tangle-v0.1.2/cargo-tangle-installer.sh | sh

Or, if you prefer to install the CLI from crates.io:

cargo install cargo-tangle --force # to get the latest version.

🚀 Getting Started

Once cargo-tangle is installed, you can create a new project with the following command:

cargo tangle blueprint create --name <project-name> --eigenlayer <type>

where <project-name> is the name of the project that will be generated, and <type> is BLS or ECDSA. If you aren't sure which type to use, you likely want the default: BLS. After all, this is the template for BLS. If you don't specify a type, it will default to BLS.

Upon running the above command, you will be prompted with questions regarding the setup for your generated project. If you aren't sure for any of them, you can just hit enter to select the default for that questions.

Note

If you choose to use foundry.toml for the Soldeer configuration (the default), you will need to delete the following files from the contracts directory:

• foundry.toml
• remappings.txt
• soldeer.lock

This will allow the generated project to work out of the box. This will be fixed in the future, so that nothing needs to be deleted.

📚 Overview

This project is about creating a simple Hello World AVS for EigenLayer. An AVS (Actively Validated Service) is an off-chain service that runs arbitrary computations for a user-specified period of time.
