LayerZero Scan Overview

LayerZero Scan is a block explorer specifically for observing cross-chain transaction activity facilitated by LayerZero. Here’s how to get started with navigating it:

What Is LayerZero Scan?

LayerZero Scan is designed to display cross-chain messaging details such as:

• Transaction hashes and bridging events across multiple chains
• Source and destination chain info
• Status of messages (in-flight, delivered, failed)
• On-chain addresses (contracts, wallets) participating in bridging

The interface consolidates data from multiple blockchains to provide a single view of cross-chain messaging.

Key Sections in LayerZero Scan

1. Search Bar

   • Allows you to search by cross-chain transaction hash, contract address, or user address.
   • If you have either the source or destination transaction, you can directly see that message’s status across source and destination.

2. Recent Transactions / Messages

   • Displays the most recent cross-chain messages.
   • For each message, you can see:
     • The source chain and destination chain
     • A short snippet of addresses involved
     • A timestamp of when it was sent

3. Detailed Message View

   • When you select a transaction or message, you’ll see a breakdown of:
     • Gas usage
     • Bridging fees
     • Source Tx Hash (links to the chain’s native block explorer, e.g., Etherscan)
     • Destination Tx Hash (if it’s already executed)

4. Address / Contract Page

   • Searching for an address (or contract) shows all cross-chain messages that address is involved in.
   • Great for debugging bridging from a specific user or checking on a particular protocol’s bridging activity.

5. Default Configurations Per Chain Pathway

   LayerZero Scan now includes a feature to check the default configuration settings for each chain pathway. This section lets you view and verify key settings that govern how messages are routed across chains. The default configuration display includes:

   • From/To: The source and destination chains for the pathway.
   • Send Library: The default library used for sending messages.
   • Receive Library: The default library used for receiving messages.
   • DVN 1 & DVN 2: The default Decentralized Verifier Networks used for message verification.
   • Executor: The default executor responsible for processing messages.
   • Send Confirmations / Receive Confirmations: The number of confirmations required on each side.

   A Reset option is provided to revert any custom configurations back to these defaults.

   From/To	Send Library	Receive Library	DVN 1	DVN 2	Executor	Send Confirmations	Receive Confirmations
   ETH/Solana	Library A	Library B	DVN A	DVN B	Executor X	5	3

6. Statistics / Additional Tabs

   • Depending on the version, you might see stats like total messages, volume, or top bridging pairs.

Why Use LayerZero Scan?

• Visibility: View exactly how a cross-chain transaction or bridging message was routed.
• Debugging: If your cross-chain message fails, you’ll see error statuses or partial deliveries.
• Confirming: Ensure your bridging transaction has arrived on the destination chain with finality.
