LayerZero is an innovative open-source, immutable messaging protocol, that connects blockchains (50+ and counting) to enable omnichain interoperability for blockchain applications. With LayerZero, developers have the power to create applications that can seamlessly interact across multiple blockchains.
Refer to the LayerZero V2 Docs for implementing, handling, and debugging LayerZero contracts.

Developers can easily send arbitrary data, external function calls, and tokens with omnichain messaging while preserving full autonomy and control over their application:
- OApp: a generic message passing interface to send and receive arbitrary pieces of data across different blockchains. See the OApp Quickstart to start building.
- OFT: enables fungible tokens to be transferred across multiple blockchains without asset wrapping or middlechains. See the OFT Quickstart to learn more.
For legacy support for LayerZero V1, refer to the Endpoint V1 documentation.
See reference implementations for how the DVN and Executor communicate with the Ultra Light Nodes on each chain.
- DVN: Developers can run a custom DVN by deploying a DVN contract on every chain they want to support. See the Build DVN guide to create your own security providers.
- Executor: Developers can deploy a custom Executor to ensure the seamless execution of messages on the destination chain. See the Executor guide.
