Hardhat Toolbox

The LayerZero Hardhat Toolbox provides developers with a framework for building, configuring, and deploying omnichain applications within their local Hardhat environment.

Installation​

Refer to the LayerZero Toolbox for specific instructions.

yarn add @layerzerolabs/toolbox-hardhat
pnpm add @layerzerolabs/toolbox-hardhat
npm install @layerzerolabs/toolbox-hardhat

Features​

This toolbox offers a streamlined approach for working with LayerZero, providing essential tools for developers to efficiently manage their OApps.

Wiring OApps​

  • Function: lz:oapp:wire

  • Description: This task is essential for creating interoperable networks of OApp contracts. By using the setPeer method, the toolbox allows different OApp contracts to establish seamless communication across various blockchain networks.

  • Benefits: Enables a network of OApp contracts to function cohesively, sharing data and resources effectively.

Building Message Options​

  • Description: Message Options are serialized instructions within a structured bytes array, allowing the OApp owner or sender to specify instructions for the Executor. These can dictate aspects like gas usage on message execution, specific messaging type handling, and more.

  • Benefits: The SDK simplifies the process of creating Message Options, which are crucial for specifying how messages are handled and executed on the destination chain.

Configuring OApps​

  • Description: Configuration of OApps involves setting up the application's security stack and executors. This step is crucial to ensure that the application operates securely and efficiently.

  • Benefits: Enhances the security and performance of OApps, providing a robust foundation for their operation.

Deploying OApps​

  • Description: The deployment function covers the process of deploying OApps to testnet and mainnet blockchains from the local development environment. This includes initial setup and network-specific configurations.

  • Benefits: Facilitates a smooth transition from development to live operation on various blockchain networks, allowing for thorough testing and reliable deployment.
