About

LayerZero is a messaging protocol that connects 150+ blockchains, enabling seamless communication and value transfer between them. With Omnichain Fungible Tokens (OFTs), developers can make any token move natively across multiple chains without wrapped assets or fragmented liquidity. Using LayerZero’s SDKs and smart contract templates, hackers can build omnichain DeFi protocols, cross-chain services, and interoperable applications.

Build the best omnichain application using LayerZero’s cross-chain messaging protocol and Omnichain Fungible Token (OFT) standard. Projects should demonstrate seamless token or data movement across multiple blockchains. Whether it’s a DeFi protocol, game, NFT marketplace, or novel cross-chain tool, the most innovative and technically sound implementations of LayerZero’s architecture will win. Judges will evaluate creativity, functionality, and how effectively the project leverages omnichain interoperability.

Qualification Requirements

To qualify for the Best Omnichain Implementation track, participants must adhere to the following criteria: 1. Interact with the LayerZero Endpoint contract using either the LayerZero Contracts Library or your own custom integration to send / receive a cross-chain message. 2. Extend the Base Contract Logic: It's not sufficient to simply inherit the OApp / OFT / Endpoint interface contracts; the developer must also extend it. This means adding new functionalities, features, or optimizations that create new cross-chain use cases. The extension should demonstrate innovation and an advanced understanding of the LayerZero tech-stack. 3. Working Demo: Hackathons have a tough time crunch, and we respect you all for learning to work with our tools so fast! Please focus on having the core contract working, and clean the rest up after. 4. Feedback Form:When hacking, hard to use, buggy, or confusing documentation and tooling can ruin your experience! Please take the time to submit any feedback that you think might be useful for how we can improve your lives when building on LayerZero! The best feedback submission will win $750! Please submit using the form linked under "Resources".
