31st Jan→ 7th Feb ⌛️

Our goal is to establish and expand the starknet open-source community. We are thrilled to bring the brightest brains from across the world together to work and learn from one another. Join us for a week of building and learning! This event is free, but registration is required. Apply now if you're an open-source developer builder, with or without a project!

Some of the selected projects

⚠️ We will identify a project for open-source developers of all levels, whether experienced or inexperienced. ⚠️

Cairo Foundry

Blazingly fast testing framework for Starknet contracts development inspired by Foundry

Starknet React

StarkNet React is a collection of React hooks for StarkNet. It is inspired by wagmi, powered by starknet.js.


Damn Vulnerable DeFi is the wargame to learn offensive security of DeFi smart contracts. Contribute to port and adapt the project from Ethereum to Starknet


A trustless StarkNet Light Client, ⚡blazing fast ⚡ and powered by Rust 🦀


Kakarot is an Ethereum Virtual Machine written in Cairo. It means it can be deployed on StarkNet, a layer 2 scaling solution for Ethereum, and run an EVM bytecode program.


cairo-rs is a Rust implementation of the Cairo VM. Cairo (CPU Algebraic Intermediate Representation) is a programming language for writing provable programs, where one party can prove to another that a certain computation was executed correctly. Cairo and similar proof systems can be used to provide scalability to blockchains.


Imagine interacting with a highly customizable account using your phone in the morning, your laptop during the day, and your hardware wallet at home. Introducing Fresh, Ledger's secure web wallet.

<aside> 📨 Who is organizing this?


<aside> ✨ We are OnlyDust, a company committed to supporting developers and open-source initiatives. We help fund a diverse range of open-source projects. With the help of the Starknet Foundation and Starkware, OnlyDust is organizing this Starknet Building Tel Aviv.


<aside> 📨 Why are we doing this?


<aside> ✨ The Starknet Foundation has established a method to incentivise builders by collecting a fee from all financial transactions within their ecosystem and allocating it to developers that build public goods. However, while it is simple to transfer money to Smart Contract Developers, it is more difficult to do so properly to open-source Developers.

If a fair means to share the money cannot be established, the system will finance mercenaries rather than mega chad builders, and will thus collapse. Our objective is to develop a fair distribution system in order to make this remarkable endeavor a success.
