LayerZero

Overview

LayerZero provides omnichain messaging infrastructure that allows smart contracts to communicate across different blockchain networks.

On Pharos, LayerZero enables developers to build applications that send messages and transfer assets across multiple chains, with configurable security through Decentralized Verifier Networks (DVNs).

Network Configuration

LayerZero is available on Pacific Mainnet with the following configuration:

When to Use LayerZero

LayerZero is typically used for:

• Sending messages across chains
• Building omnichain applications
• Coordinating contract logic across multiple networks
• Use cases requiring flexible security configuration via DVNs

Integration Notes

• Use Endpoint V2 contracts to send and receive cross-chain messages
• Configure DVNs based on your application's security requirements
• Suitable for applications that require customizable cross-chain messaging
