LayerZero

LayerZero is the omnichain messaging protocol that enables secure, low-level communication between over 30 disparate blockchains.

LayerZero is an omnichain messaging protocol: it acts as a foundational communication layer for decentralized applications (dApps). The architecture uses immutable on-chain Endpoint contracts, paired with a decentralized Oracle (e.g., Chainlink) and a Relayer, to securely pass messages between chains. This modular design allows each application to configure its own security stack, effectively eliminating the single point of failure common in monolithic bridges. Since its March 2022 launch, the protocol has connected over 30 blockchains and processed more than 15 million messages. LayerZero Labs secured a $120 million Series B funding round in April 2023, validating the technology with a $3 billion valuation.
