Explore LayerZero V2

LayerZero V2 is an open-source, immutable messaging protocol designed to facilitate the creation of omnichain, interoperable applications.

Developers can easily send arbitrary data, external function calls, and tokens with omnichain messaging while preserving full autonomy and control over their application.

LayerZero V2 is currently live on the following Mainnet and Testnet Chains.

Getting Started

Security

LayerZero Labs has an absolute commitment to continuously evaluating and improving protocol security:

• Core contracts are immutable and LayerZero Labs will never deploy upgradeable contracts.

• While application contracts come pre-configured with an optimal default, application owners can opt out of updates by modifying and locking protocol configurations.

• Protocol updates will always be optional and backward compatible.

LayerZero protocol has been thoroughly audited by leading organizations building decentralized systems. Browse through past public audits in our Github.
