🔮 Best LayerZero Read ⸺ $7,500

🥇

1st place

$5,000

🥈

2nd place

$2,500

Develop a comprehensive solution using LayerZero Read to request, retrieve, and process external on-chain state from destination blockchains. Your solution should leverage the lzRead protocol to perform cross-chain data queries, utilize LayerZero's Blockchain Query Language for constructing and executing these queries, and update the state on the source or another destination chain based on the retrieved data. Emphasis should be placed on security, efficiency, and seamless data synchronization, utilizing advanced features such as sending multiple different call requests and using compute logic in the form of lzMap() and lzReduce() to perform 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. 4. Feedback Submission Submit valuable feedback on LayerZero Read tools and documentation through the provided feedback form. The best feedback submission will receive a $500 prize.
