LayerZero is an omnichain interoperability protocol that lets applications send arbitrary data, function calls, and tokens between blockchains through immutable endpoint contracts deployed on each supported chain. Each application configures its own security by choosing a set of Decentralized Verifier Networks (DVNs) and executors, and token issuers use its Omnichain Fungible Token (OFT) standard to issue a single asset natively across many chains. The protocol is developed by LayerZero Labs, while the LayerZero Foundation administers ZRO governance and operates the Stargate bridge.
