LayerZero Official: Omnichain Messaging, OFTs & V2 

LayerZero Official: Omnichain Interoperability Hub 

LayerZero Official is the foundational messaging layer that connects isolated blockchains into a unified network. This technical documentation serves as the primary resource for deploying OFT Omnichain Fungible Tokens, configuring Decentralized Verifier Networks (DVNs) in V2, and participating in ZRO Token Governance. LayerZero is the "TCP/IP" that enables data to flow securely between EVM and non-EVM chains. 

LayerZero Ecosystem: The Messaging Layer 

LayerZero is not a bridge; it is a transport protocol upon which bridges (like Stargate) and other apps are built.

Messaging, Not Bridging: Traditional bridges lock assets on Chain A and mint wrapped assets on Chain B. LayerZero simply sends a "packet" of data. How that data is interpreted (e.g., "mint 10 tokens") is up to the receiving application.

OFT Standard: The flagship use case. An OFT contract is deployed on multiple chains. When a user transfers, tokens are burned on Source and minted on Destination. This removes the risk of "Bridge Honeypots" because the liquidity is not stored in a central contract; it is elastic across the network.

V2 Architecture: The current standard. It decouples the three core components: Endpoint (Interface), Verifier (Security), and Executor (Liveness). This makes the protocol immutable while allowing security to be modular.

DVNs & Security Stacks 

The infrastructure of LayerZero V2 Protocol gives developers granular control over trust.

Decentralized Verifier Networks (DVNs): In V1, applications relied on an Oracle and Relayer. In V2, this is generalized to DVNs. These are permissionless entities that verify messages. Examples include Google Cloud, Polyhedra (ZK proofs), Animoca, and Nethermind.

Security Stack: Developers define a "Security Stack" for their app. For example, a high-value DeFi app might require validation from "3 of 5" specific DVNs (e.g., Google + Polyhedra + Their Own Node) before a message is accepted. A gaming app might accept just "1 of 1" for speed.

Executors: These agents effectively "push" the verified message to the destination chain. They compete on price and speed, ensuring users don't overpay for gas.

ZRO, Stargate & Fees 

The economy revolves around the utility of the messaging network.

ZRO Token: The governance token. $ZRO holders influence the "MessageLib" registry and control the protocol treasury.

Stargate: The first and largest application built on LayerZero. It is a composable liquidity transport protocol. Users often confuse the two; Stargate is the app, LayerZero is the network.

Protocol Fees: LayerZero V2 introduces a mechanism where the protocol (governed by ZRO) can monetize message flow, though the primary cost to users is the gas paid to Executors and DVNs.

Security, Audits, and Risks 

LayerZero Official shifts liability from the protocol to the application.

Application-Owned Security: This is the core philosophy. If an application chooses a malicious DVN, only that application is affected. There is no "Systemic Risk" where a bug in LayerZero drains all apps simultaneously (unlike a monolithic bridge).

Immutable Endpoints: The smart contracts on each chain (Endpoints) are immutable. They cannot be upgraded or paused by LayerZero Labs. This prevents "Governance Attacks" where a team key compromise could ruin the network.

Audits: The V2 codebase and the OFT standard have been audited by Zellic, OtterSec, and Trail of Bits.

Frequently Asked Questions 

What is an OFT? OFT Omnichain Fungible Token is a standard that allows you to "send" a token to another chain. It burns the token in your wallet on Chain A and mints it to your wallet on Chain B.

What are DVNs? Decentralized Verifier Networks are the entities that check if a message is valid. You can choose which DVNs you trust (e.g., Google Cloud, Polyhedra) to secure your application.

Is LayerZero a bridge? No. LayerZero is a messaging protocol. Bridges like Stargate are applications built on top of LayerZero.

What is the ZRO token used for? $ZRO is used for governance. It allows the community to vote on protocol upgrades and fee switches.
