LayerZero is an omnichain interoperability protocol that enables smart contracts to read from and write state to different blockchains. Developers can build omnichain applications (OApps) that can push/pull state, transfer value, and call smart contracts on other networks as if they were on a single blockchain.
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 LayerZeroâs 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.
How to Qualify
For the most advanced and practical financial application built using LayerZeroâs 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.
