Though blockchains are designed to be secure, facilitating safe communication between networks is challenging. LayerZero is an interoperability protocol that allows secure communication between over 80 networks for omnichain applications, such as tokens.

and rewarded builders, content creators, and onchain enthusiasts with 5 million ZRO tokens. Initiatives like Proof of Donation and Sybil filtering ensured fair token distribution and supported the protocol's long-term growth.output: LayerZero, an interoperability protocol, facilitates secure communication between over 80 networks, enabling omnichain applications to transfer tokens and other data across distinct networks. Its architecture includes immutable Endpoints for sending and receiving messages, and a permissionless set of decentralized verifier networks (DVNs) and Executors that handle verification and execution, respectively. Each independent application can configure its own security stack, including DVNs, Executors, and block confirmations, to meet the specific level of security required for sending and receiving messages.

As a standardized communication protocol, LayerZero is designed to enable omnichain applications to communicate on distinct networks in a standardized way. Its primary use case is to facilitate the transfer of arbitrary data—such as assets—between these networks, with asset transfer being the most common type of data moved. Other use cases include any application that might need to send messages between multiple chains, including gaming, cross-chain governance, identity solutions, restaking, and Enterprise products.

The initial developer and core contributor to the LayerZero protocol, LayerZero Labs raised a $120 million Series B in April 2023. LayerZero V2 went live in January 2024, featuring a common messaging system and common security properties to simplify cross-network communication and improve the developer experience. In June 2024, LayerZero launched its native token, ZRO.
