\n\n🏆 **BOUNTY PRIZE**\n\n- Prize Pool of $4,500 USD\n - **🥇 1st $2,000**\n - **🥈 2nd $1,500**\n - **🥉 3rd $1,000**\n\n🚀 **ABOUT STARKWARE**\n\n- StarkWare develops scaling solutions for the Ethereum blockchain based on STARK Validity Proofs. It has launched StarkEx – a SaaS scaling engine, and Starknet, a Layer 2 Validity Rollup. It has also developed Cairo, a Turing-Complete Programming Language.\n- Starknet is a permissionless Validity-Rollup (also known as a “ZK-Rollup”) that operates as an L2 network over Ethereum. It enables any dApp to achieve scale for its computation without compromising Ethereum’s composability and security, thanks to Starknet’s reliance on a state-of-the-art cryptographic proof system - STARK.\n\n🚀 **BOUNTY NAME**\n\n- Starknet and Cairo\n\n🚀 **CHALLENGE DESCRIPTION**\n\n- If you had much more computing power than Ethereum, an order of magnitude lower gas fees, native account abstraction, a powerful programming language and all of that secured by zk-proofs... What would you build?\n- Starknet offers all of that using the Cairo programming language.\n\nWhat you build and present for the hackathon is up to you but here are some ideas that might help you get started:\n\n- **Dojo:** If you are into gaming and want to explore the idea of Autonomous Worlds pioneered by MUD but with a more powerful programming language and a more performant environment, Dojo might be of interest to you.\n- **Storage Proofs:** If you care about cross chain interoperability without relying on faulty bridges Storage Proofs by [Herodotus](https://www.herodotus.dev/) might be what you are looking for.\n- **Account Abstraction:** If you want to focus on improving usability and onboard web2 users to blockchain, Account Abstraction supported at the protocol level combined with WebAuthn might give you the tools you need.\n- **L1-L2 messaging:** If you want to create hybrid apps where half of the logic resides on Ethereum and the other half on Starknet, you can use the native L1-L2 messaging system of Starknet to get the best of both worlds.\n\nAgain, these are just some ideas to get you started but they are not at all prescriptive. You can apply to the bounty even if you don't use any of them as long as you use Starknet or Cairo in a meaningful way.\n\n🚀 **REQUIREMENTS**\n\n- For a project to qualify for the bounty it must have one or more Starknet smart contracts or use the Cairo programming language in any way.\n\n**⚖️ JUDGING CRITERIA**\n\n- **Originality:**\n - Is your project original or a copy of an existing one?\n- **Potential Impact:**\n - If made available on mainnet, how much of an impact it would have on the Starknet ecosystem and community?\n- **Functionality:**\n - Is your demo working?\n - How close to a polished product is it?\n\n**RESOURCES**\n\n- [Starknet Website](https://www.starknet.io/en): Central hub for all things Starknet.\n- [Starknet Ecosystem](https://www.starknet-ecosystem.com/): List of all the dapps and services available on Starknet.\n- [Starknet Docs](https://docs.starknet.io/documentation/): Official Starknet documentation maintained by StarkWare.\n- [Cairo Docs](https://docs.cairo-lang.org/): Official Cairo documentation maintained by StarkWare.\n- [The Cairo Book](https://book.cairo-lang.org/): Community driven book that does a deep dive into the Cairo syntax.
