 Welcome to the solidity-examples repository, showcasing various contract examples utilizing LayerZero. LayerZero is an Omnichain Interoperability Protocol, facilitating reliable, trustless communication between different blockchain networks.
 
-**Disclaimer**: This repository contains example contracts to demonstrate the capabilities and usage of LayerZero. For actual implementation in your projects, it's recommended to use the official LayerZero contracts (such as LZApp, OFT, OFTV2, etc.) directly from the[ npm package](https://www.npmjs.com/package/@layerzerolabs/solidity-examples).
