For the project that demonstrates the most powerful and creative use of omnichain contract interactions. This prize specifically targets non-token transfer use cases that leverage LayerZero’s core messaging rails. We are looking for projects where contracts on different chains communicate and trigger complex actions with one another. Think beyond asset transfers and focus on building applications that synchronize state, share logic, or create a single, cohesive experience across multiple networks. Ideal submissions will solve problems in areas like: - Omnichain Governance: Allowing a DAO on one chain to control contracts or treasuries on others. - Cross-Chain Account Abstraction: Creating a single "smart account" that can execute transactions on any connected chain. - Omnichain Identity & State: Managing a user's data or application state (e.g., game progress, user profiles) seamlessly across chains. Omnichain Data Synchronicity: Ensuring data consistency, replicating critical states, or synchronizing off-chain data feeds across different blockchain environments. To win, your project must showcase an advanced use of OApp (push-based messaging), lzRead (pull-based messaging), and/or Composer (subsequent messaging) to facilitate this interaction. Projects that creatively combine these messaging models will be viewed favorably.

For the most advanced and practical financial application built using LayerZero’s token standards. This prize is for projects focused on the secure and efficient omnichain transfer of value. We are looking for builders who are creating novel DeFi primitives, extending the functionality of existing tokens (e.g., ERC20, ERC4626, ERC721), or building new types of omnichain infrastructure. Your goal is to demonstrate how LayerZero can eliminate liquidity fragmentation and create a more unified crypto ecosystem. Ideal submissions will build novel solutions like: - Omnichain Yield-Bearing Tokens: Creating or extending an ERC4626 vault or similar yield-bearing token, allowing users to deposit on one chain and have their liquidity put to work on another. - Advanced Tokenization: Implementing a creative use of the OFT Standard to bring new utility to an existing token or using the ONFT standard to represent unique financial positions or assets. - Complex Value Transfer: Using Composer to build sophisticated, multi-step financial transactions. For example, a cross-chain swap that allows a user to send Token A on Chain X and seamlessly receive Token B on Chain Y. - Cross-Chain Lending & Collateral: Building a protocol where assets on one chain can be used as collateral for borrowing assets on a different chain. To win, your project must be built upon the OFT or ONFT standards. Implementations that leverage Composer for subsequent value transfer operations will be highly regarded.

Consumer-oriented “killer apps” have the power to define and lead entire industries by solving real user pain points at scale. Think of how ChatGPT made AI accessible to hundreds of millions. Flow is designed for mass adoption and consumer-grade experiences, so we’re looking for the next breakthrough application that can capture the interest of millions (or billions!) of everyday users. This is a very broad bounty and eligible projects include everything from AI Agents and RWA to games and social apps.

Flow Actions (FLIP-338) are a brand-new standard that turn protocol logic into self-contained, reusable onchain building blocks you can call without importing ABIs, reading contract code, or writing brittle glue scripts. Each Action is a trustless workflow with clear metadata, built-in safety checks, atomic execution, and verifiable success criteria—think standardized onchain APIs that plug together like Lego bricks. For AI agents, this means instant discovery of available protocols, safe composition of complex workflows, and full automation without off-chain keepers or MCP servers. This bounty is calling on builders to push the boundaries by creating new connectors to major protocols, chaining cross-protocol workflows, integrating Actions into games, integrating fully onchain agents with actions, or making tools that help others discover and use useful Actions. Whether you’re into DeFi, gaming, or novel automation, this is your chance to shape the future of composability and define how agents interact with Web3.

Ship anything on Flow mainnet or testnet. Deploy a contract or send a transaction on Flow. If you interact with the Flow network during the hackathon, you're in. Did you know that last month $420k was funded into various projects that built on Flow? Most of that funding went to projects that hacked on Flow before but did not manage to win top prizes. Hackathons are just the beginning of your support, when you find your Flow State, everything flows!

Build a Great Onchain App Using CDP We’re looking for high-quality onchain apps that use at least one of the following Coinbase Developer Platform tools: ✅ Coinbase Onramp ✅ CDP Wallets (Server or Embedded) ✅ CDP Data APIs (Token Balance, Event, SQL API) ✅ x402 No fixed categories - just ship something real, useful, or delightful. 📌 Sample Ideas A web or mobile app that lets users buy crypto or fund wallets with Onramp An AI agent that streams micro-payments using x402 A collaborative wallet that automates shared expenses A personal finance dashboard using CDP Data APIs A marketplace with wallet-native checkout

Any type of ENS integration is eligible for this prize. Get creative! An example of a successful project may be a smart contract wallet that mints an ENS subname on L2 and sets its primary name upon deployment. If you're building an AI project, consider how ENS can be used to name autonomous agents. Come by our booth for help brainstorming ways to integrate ENS into your project!

ENS Primary Names are the ability to fetch a name like gregskril.eth for an Ethereum address like 0x179A...9285, bringing a sense of identity into your application. This functionality was recently deployed to Arbitrum, Base, OP Mainnet, Linea and Scroll. Anywhere an address is visible in your app, you should show an ENS name instead!

The best project that deploys on Zircuit will win this prize. The code should be well engineered, tested, and have a compelling use case. These gems are the projects that will inspire future hackathon projects because of their outstanding quality. Remember: deploying on Zircuit is as easy as changing your endpoint in your favorite development framework. As long as the contracts are deployed on Zircuit and verified, the project is eligible. A successful submission will include a functional prototype that solves the problem it’s intended to address. It will showcase some innovation/creativity, either through technological or UI improvements. It may be complete and solve a long-standing open problem or introduce something with a lot of potential for future development. Either way, it has an impact on the Zircuit ecosystem. Winning projects should have a user-centered design that makes it easy for the target audience. This can be end users or developers integrating the project into their own codebase. The best may also include clean and consistent visual designs. Any interesting blockchain applications are welcome. Novel ideas are more impressive than clones of existing projects, though there are certainly times where clones include significant improvements. Those that are very technical may impress the judges if done correctly but simpler ideas may be easier to do well. This bounty will be judged based on completeness, execution, and creativity.

Have a world-changing idea but not necessarily any code? This is your chance to shape the future of the Zircuit ecosystem with nothing but your creativity and strategic thinking. The best submission will be a compelling, well-architected concept for a “killer app” on Zircuit—an application so impactful it inspires builders, excites users, and becomes a reference point for future innovation. This prize is for visionary thinkers, and code isn’t required. We're looking for: - A clear and detailed problem statement - A compelling solution that leverages Zircuit’s unique capabilities (Sequencer level security, account abstraction support, or simply the network performance) - A functional architecture diagram or component layout (this can be text or image based, but be sure to convince us that you’ve thought about the pieces) - A well-written pitch: how it works, why it matters, and who it’s for. Winning projects may also include user journeys, token mechanics (if applicable), market research, and plans for future development.
