# What’s Happening? Ethereum is entering its next chapter: statelessness, modularity, and AI-native tooling. From zkVMs and MPC to ERC-4337 and MEV-resistant design—there’s never been a better time to ship something that breaks the mold. This is your call to experiment. Whether you're optimizing rollup infra, proving intent-based UX, or bringing quantum-safe cryptography to smart contracts—this hackathon is your testnet for invention. ### Joining our [Discord server](https://discord.gg/qFfvVB5KTw) is mandatory for hackathon participation. --- # Who’s it for? Builders who: - Get excited by Cairo bytecode audits and zkEVM benchmarks - Think “blockspace is abundant, but attention isn’t” - Are tired of talking about modular chains and ready to *build* them - Want to ship on battle-tested EVM infra and reach real users fast --- # Tracks **1. Smart Account UX & Abstraction** Reimagine onchain interaction with account abstraction. Explore session keys, social recovery, and frictionless onboarding. **2. Next-Gen Infrastructure** Push the boundaries with zk rollups, blob streaming, stateless validation, and alt data availability layers. **3. Security & Privacy Tooling** From MEV resistance to fully homomorphic encryption and L2 privacy circuits, build for resilience and user sovereignty. **4. DeFi, RWAs & Autonomous Apps** Design composable, permissionless economic systems that bridge the digital and physical - onchain treasuries, credit, insurance, or AI agents with wallets. --- # Why Join? - Build on the EVM stack with real usage in mind - Get visibility from top infra teams and DAOs - Win a share of $30,000 in prizes - Connect with hackers from around the world - And most importantly, ship something weird and worthwhile --- # Timeline (Updated) - **Hackathon Starts:** July 03, 2025 - **Submissions Close:** August 10, 2025 - **Judging & Demos:** August 12 – 19, 2025 - **Winners Announced:** August 22, 2025 --- # Submission Criteria Submit a BUIDL on Dorahacks with your team details, Github repo and a demo video. Your code repo has to include the OKX DEX API ([technical docs here](https://web3.okx.com/build/dev-docs/dex-api/dex-what-is-dex-api)) integration or you will be automatically disqualified. Bonus points if you can also explain how you can potentially work with [XLayer](https://web3.okx.com/xlayer). When submitting your BUIDL, you will be prompted to enter a password, which you can find in our Discord server. All the best! **Push the protocol.** **Invent new primitives.** **Don’t just build apps - build the future.**
