Build and deploy omnichain applications with crosschain messaging. Follow step-by-step developer in... [LayerZero Scan](https://layerzeroscan.com/) is a comprehensive search, API, and analytics platform designed to streamline the experience for developers and users dealing with omnichain transactions. LayerZero Scan homepage showing key statistics including Total Messages, Inflight Messages, Volume, Total UA, and Networks, along with a live feed of crosschain messages displaying their status, transaction hashes, protocol, and timestamps LayerZero Scan homepage showing key statistics including Total Messages, Inflight Messages, Volume, Total UA, and Networks, along with a live feed of crosschain messages displaying their status, transaction hashes, protocol, and timestamps ## Overview Scan offers an enhanced developer experience for working with omnichain transactions in the LayerZero protocol by providing: * **Unified Message Explorer**: Track LayerZero transactions across multiple chains within a single interface. * **Protocol Analytics**: Monitor marketwide trends and the state of the ecosystem through detailed analytics. * **Scan Client**: Interface your frontend applications with omnichain transaction logs seamlessly. Developers can monitor transactions on both the [Mainnet Explorer](https://layerzeroscan.com/) and [Testnet Explorer](https://testnet.layerzeroscan.com/). ## Transaction Statuses Transaction status badges showing six states: Delivered (green), Inflight (yellow), Payload Stored (purple), Failed (red), Blocked (gray), and Confirming (gray outline) Transaction status badges showing six states: Delivered (green), Inflight (yellow), Payload Stored (purple), Failed (red), Blocked (gray), and Confirming (gray outline) * **Delivered**: The message has been successfully sent and received by the destination chain. * **Inflight**: The message is waiting for source block confirmations, verification, or execution on the destination chain. * **Payload Stored**: The message arrived at the destination, but reverted or ran out of gas during execution and needs to be retried. * **Failed**: The transaction encountered an error and did not complete. * **Blocked**: A previous message nonce has a stored payload, halting the current transaction. * **Confirming**: The destination transaction has been submitted and is waiting to reach finality on the destination chain. ## Protocol Analytics Users can also monitor protocol and chain analytics, making it easy to observe market wide trends and understand the current state of the ecosystem.
