About

Beerus is a StarkNet Light Client inspired by and using helios. The goal is to provide a simple and easy to use client to query StarkNet state and interact with contracts.

Built With

Architecture

Here is a high level overview of the architecture of Beerus.

Simple usage overview

Here is a simple overview of how Beerus work. The example is for querying a storage value of a StarkNet contract.

Getting Started

Installation

Beerusup

To install with beerusup:

curl -sL https://raw.githubusercontent.com/keep-starknet-strange/beerus/main/beerusup | sh

Build

cargo build --all --release

Build beerus-core for WASM:

cargo build -p beerus-core --no-default-features --target wasm32-unknown-unknown --release

Test

cargo test --all

Config

The project requires an Ethereum node and a Starknet node. For Ethereum nodes you can use Alchemy (not Infura since it does not support getProof endpoint).

Ethereum execution layer RPC URL (must be an Ethereum provider that supports the eth_getProof endpoint).

Ethereum consensus layer RPC URL (must be a consensus node that supports the light client beacon chain api)

For StarkNet node for the moment you can use Infura but soon verify proof will be implemented in Pathfinder nodes, and so will these nodes be working as well.

Config File

Beerus is configurable via a config toml. If you have set the env var BEERUS_CONFIG = path/to/config this will override all other environment variables and take configuration from values defined herein. Also the the cli can be directed via beerus --config <path/to/config>

goerli.toml

mainnet.toml

Environment Variables

Beerus is configurable through environment variables.

cp examples/.env.example .env
source .env

Beerus CLI

cargo run --bin beerus starknet query-state-root

Beerus RPC

cargo run --bin beerus-rpc
