About the Hackathon

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 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

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) integration or you will be automatically disqualified. Bonus points if you can also explain how you can potentially work with 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.
