LayerZero is an omnichain interoperability protocol that enables seamless communication between different blockchains. It allows developers to build omnichain applications (OApps) that can interact across multiple chains as if they were on a single chain.
Why build with LayerZero at a hackathon
— Reach More Users: Deploy your dApp once and interact with users and assets across all supported chains.
— Unify Liquidity: Avoid fragmented liquidity; build DEXes, lending platforms, etc., that leverage a shared cross-chain pool.
— Simplify Development: Build complex cross-chain logic using familiar tools (Hardhat, Foundry, etc.) and LayerZero's contract standards (OApp, OFT, ONFT). Get started quickly with the create-lz-oapp CLI.
— Enhance Security: Benefit from a configurable, decentralized security model using Decentralized Verifier Networks (DVNs).
— Improve User Experience: Abstract away cross-chain complexities, offering seamless interactions without users needing multiple wallets or bridging steps.
— Innovate: Explore novel use cases like cross-chain governance, gaming, data queries (lzRead), and complex multi-step workflows (Composability).
Prizes

1st place
$2,500
🥈
2nd place
$1,500
Develop a comprehensive solution using LayerZero Read (lzRead) to request, retrieve, and process external on-chain state from destination blockchains.
Your solution should use lzRead to perform cross-chain data queries and update state on the source or another destination chain based on the retrieved data.
Projects should focus on secure and efficient cross-chain data queries, using features like lzMap() and lzReduce() for off-chain computation.
Qualification Requirements
1. Utilization of LayerZero Read Features
Implement the lzRead protocol to perform cross-chain data retrieval from at least one supported destination blockchain. Use LayerZero's Blockchain Query Language (lzRead) to construct and execute data queries across multiple chains.
2. Effectively request and retrieve on-chain state data from a destination blockchain using lzRead.
Process the retrieved data and update the state on the source blockchain or another destination chain based on the retrieved information.Demonstrate seamless synchronization and utilization of the updated state across the involved blockchains.
3. Working Demonstration
Provide a working demo of your solution, showcasing the complete workflow from data retrieval using lzRead to state updates across chains. If the implementation is complex, ensure that all key functionalities are effectively demonstrated.
Build an innovative application that showcases LayerZero's horizontal composability features. Your project should break down a complex cross-chain workflow into discrete, sequential steps managed through LayerZero messages.
Demonstrate how you can trigger follow-up actions (composed messages) on a destination chain after an initial LayerZero message is delivered, potentially involving interactions with multiple contracts or protocols across different chains.
Focus on creating advanced, multi-step workflows that wouldn't be easily possible with traditional bridging or single atomic cross-chain transactions. Show how this approach improves user experience, reliability, or enables new use cases by decoupling operations and leveraging LayerZero's message-passing framework.
For outstanding projects utilizing any LayerZero feature (OApp, OFT, ONFT, lzRead, Composability) to build a compelling omnichain application.
This track rewards creative and well-executed projects that demonstrate the power and potential of LayerZero, even if they don't fit perfectly into the specific lzRead or Composability tracks. Show us your best omnichain ideas!
Qualification Requirements
1. Omnichain Messaging:
Implement omnichain messaging solution via LayerZero integration, ensuring the application is built on Endpoint V2 for seamless cross-chain communication.

Flow is a layer one blockchain with a powerful smart contract language (Cadence) and full EVM equivalence (any Solidity, smart contract, or protocol that works on Ethereum or an EVM L2 works on Flow). The network was designed from the ground up to enable consumer crypto applications that scale to mainstream audiences and seamlessly connect to digital ecosystems. It is based on a unique, multi-role architecture, and designed to scale without sharding, allowing for massive improvements in speed and throughput while preserving a developer-friendly, ACID-compliant environment.
Flow has been architected with a clear vision for the future of consumer crypto, and meticulously designed to address the shortcomings of earlier blockchains to ensure scalability, usability, and efficiency are not simply an afterthought. By incorporating critical protocol-level primitives, such as account abstraction and on-chain randomness, as well a powerful transaction model and scalability without sharding, Flow sets itself apart as a blockchain made for those interested in building apps for widespread adoption and developer-friendly innovation.

Beraborrow is the leading collateralised debt position (CDP) protocol on Berachain, unlocking instant liquidity through Nectar ($NECT), the first stablecoin powered by Proof of Liquidity. Designed for simplicity and flexibility, Beraborrow features modular, tokenized components that can be composed together to introduce powerful new features to the CDP design space.
Prizes
🌊 Best use of the LSP for stabilizing another protocol ⸺ $2,500
Liquid Stability Pool offsets the debt of liquidations in our CDP module, we believe we can bring higher capital efficiency to the $NECT sitting there by having other protocols (Perpetuals, Lending…) making use of that available liquidity, with the condition that it ends up being profitable to LSP holders.
Develop a module that can plug into the `LiquidStabilityPool::offset()` function, ensuring that any other protocol can make use of its liquidity, without introducing any liquidity problem.
Qualification Requirements
Qualification requirement:
- Projects must have a description and a GitHub repository with a descriptive README.
-- How your module safely leverages LSP liquidity.
-- Why it's beneficial to both protocols and LSP depositors.
- There has to be at least one practical example of a known protocol making a sound use of your developed module that plugs into the LSP.
- Technically and economically sound.
- Code must be open source and modular enough to plug into future protocols.
- Berachain smart contract deployment.
Examples:
- Lending liquidations (Aave, Dolomite)
- Perpetuals liquidations (GMX, Hyperliquid…)
📈 Best tokenized strategy on CDP positions ⸺ $2,500
Create a vault strategy on Beraborrow that automatically manages a CDP. Let users “set it and forget it”—but optimize for sustainability, yield, risk, and usability.
Our product, Managed Leveraged Vaults (MLV), keeps the position collateral ratio constant, while depositing the debt into our LSP, and rebalancing PoL rewards into principal.
Qualification Requirements
- Projects must have a description and a GitHub repository with a descriptive README.
- As ERC4626 compliant as possible.
- Technically and economically sound.
- Deployed smart contracts over any Beraborrow collateral.
