This section of the documentation covers three key resources that help developers inspect and integrate with LayerZero’s crosschain infrastructure. Below is a summary of what each tool does and when you might want to use it.

​
LayerZero Scan (UI)

The LayerZero Scan overview page explains the web-based block explorer that showcases:
  • Crosschain transactions (messages) in a unified interface
  • Source/destination chain details for any bridging operation
  • Individual transaction status (delivered, pending, or failed)
  • Address search to view bridging events associated with a particular user or contract
Use it if:
  • You need a visual way to check crosschain TX status.
  • You want to see real-time bridging volume or debugging info for your messages.

​
LayerZero Scan Swagger API

The API page documents the Swagger-based endpoints that expose the same crosschain transaction data as the web UI, but in a programmatic manner:
  • GET /messages/tx/{tx} to fetch message details
  • GET /messages/wallet/{srcAddress} to Retrieve messages initiated by a specific wallet address.
  • Query-based endpoints to filter or search messages by chain, status, or time
Use it if:
  • You want to automate crosschain transaction queries (e.g., in a custom dashboard).
  • You need to poll or monitor message statuses at scale (like for bridging analytics or notifications).

​
LayerZero Endpoint Metadata

The Endpoint Metadata page details a comprehensive JSON file that maps:
  • All known LayerZero chain deployments (bridging contract addresses, RPC endpoints, etc.)
  • Token metadata on each chain (addresses, decimals, pegging info)
  • DVNs (Decentralized Verifier Network addresses), chain explorers, environment flags, and more
It also explains how you can:
  • Programmatically configure bridging by reading the deployments or tokens fields.
Use it if:
  • You want to ensure you have the latest official addresses rather than manually hardcoding them.

​
Putting It All Together

  • LayerZero Scan (web UI) → Quick visual debugging, real-time transaction lookup.
  • LayerZero Scan API → Programmatic crosschain transaction data retrieval and stats.
  • Endpoint Metadata → Full listing of chain configs, bridging contracts, and tokens for advanced integrations or dynamic UIs.
Consider each tool a different piece of the puzzle:
  • The Scan explorer helps confirm if a bridging transaction arrived safely.
  • The Scan API helps you build your own custom dashboards or monitoring scripts.
  • The Endpoint Metadata ensures your application always references the correct bridging addresses, token definitions, etc., across all LayerZero-supported networks.
