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.

Qualifications

How to Qualify 1. Deploy a LayerZero V2 Contract: Your project's core logic must utilize a LayerZero V2 standard. 2. Public GitHub Repository: Your source code must be publicly accessible. 3. Show a Working Demo: Post a LayerZero Scan transaction hash showing your project in action. 4. Complete Submission Form: All participants must complete the Feedback form linked below.

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.

Build something awesome using Chainlink CCIP and/or CCT Standard! This track purely focuses on implementations that make sense in a multi-chain world and use CCIP and/or CCT standard to enable seamless interoperability. - The Chainlink Cross-Chain Interoperability Protocol (CCIP) provides a single simple interface through which dApps and web3 entrepreneurs can securely meet all their cross-chain needs, including token transfers and arbitrary messaging. - The Cross-Chain Token (CCT) standard offers a streamlined and decentralized approach to enabling token transfers across blockchains using Chainlink's Cross-Chain Interoperability Protocol (CCIP). Traditionally, token developers had a friction-laden and manual process to enable their tokens for cross-chain operations. Use our CCIP Local to speed up your development on your local Hardhat, Foundry or Remix network, then use our Faucet to easily get testnet funds when you're ready for testnet. Links to both at the bottom in the 'Resources' Section!

Qualifications

- Each project must use Chainlink CCIP and/or CCT Standard in some form to make a state change on a blockchain, otherwise it will not be eligible for the Chainlink core prizes. This means that a front end simply reading from Chainlink Data Feeds doesn't count. Using Chainlink CCIP inside your smart contracts is required, though you are encouraged to utilize Chainlink Data Feeds, Chainlink Data Streams, Chainlink VRF, and Chainlink Proof of Reserve as well.

Build something awesome using Chainlink! Anything that came from the Chainlink Documentation counts - using Price Feeds, Data Streams, PoR, VRF, Automation or Chainlink Functions!

Qualifications

Please note: The Oasis Foundation reserves the right to adjust the reward structure based on the quality and relevance of the submissions received. What to build: ROFL (Runtime Off-chain Logic) apps run inside a Trusted Execution Environment (TEE). They rely on Sapphire for registration, billing, virtual machine management, and secure storage of secrets and configuration. Execution within ROFL takes place entirely off-chain, making it ideal for compute-intensive or always-on services such as secure decentralized oracles, bridges, AI agents, LLM chatbots, and more. Redundancy is possible with native support for replicas. Apps running in ROFL can also access its key management service, allowing Sapphire smart contracts to verify that a transaction was genuinely signed from within the TEE.

We’re looking for sticky, culture-driven products — something fun, useful, and interactive. If it runs on Ronin and users want to try it out, we want to see it.Ship something real for a chain where users actually show up and use what you build.

Qualifications

- Integrate Ronin’s Wallet SDK (onboarding, auth, session management) - Deploy a smart contract & run transactions on Saigon testnet/Ronin mainnet

Build an application that sets the benchmark for simplicity and user experience in web3. We are looking for innovative solutions across the DeFi, Web3 Gaming and AI Agents domains.

Qualifications

- Smart contract deployed on a Saga Chainlet (Reach out to TG: @DeJen for access) - Projects must have a accessible UI/frontend, and a GitHub repository with a descriptive README which includes a short description of your submission and why you chose Saga chainlet

VibeJam – Build Freely with the Katana Starter Kit For flowstate coders, AI prompt wranglers, and vibesmiths who want to create without constraints. The VibeJam celebrates experimental, creative, and playful building using the Katana Starter Kit - a local, LLM-enabled developer kit that spins up a snapshot of the Katana chain for fast iteration and testing. There’s no rigid spec and no requirement to use specific primitives. Just build something cool, composable, and fun. Your project might be: - A new DeFi primitive with a unique mechanism - An AI-agent flow using Katana state - A meme-based yield game - A tool that helps other Katana hackers - A custom frontend for a Katana vault The only requirements: - Use the Katana Starter Kit - Deploy something to Katana Tips: - Join us for Forge on July 1st for demos, onboarding, and free Cursor licenses for qualifying hackers - Need inspiration? Explore the Katana Flywheel simulator (https://flywheel.bruno.id) or browse the starter kit repo for example contracts

Qualifications

Judging Criteria: - Technical Creativity - Reusability: Can others build on your hack? Did you build on others? - Vibe: Is it fun, useful, or meme-worthy? - Use of the Starter Kit: Bonus points for creative LLM flows or integrations with Katana primitives (extra points if you make a PR for the kit, or a constructive suggestion)

Delta-Neutral LP Strategies Create automated rebalancing systems for uncorrelated pairs. Pooled EulerSwap Instances Build shared liquidity management platforms. Custom AMM Implementations Design novel curve types for specific market conditions.
