Protocolo LayerZero

LayerZero is an open-source omnichain interoperability protocol designed to enable decentralized applications (dApps) to communicate and transfer data seamlessly across multiple blockchains. It provides a low-level messaging primitive that allows smart contracts to send and receive arbitrary data, tokens, and function calls across chains with high security and censorship resistance. The protocol is immutable and permissionless, allowing anyone to run infrastructure components such as Decentralized Verifier Networks (DVNs) and Executors to support message validation and execution.

The core of LayerZero consists of immutable Endpoint contracts deployed on each supported blockchain, which serve as entry and exit points for cross-chain messages. Developers build omnichain applications (OApps) using LayerZero’s standards like OApp for generic message passing, OFT (Omnichain Fungible Token) for cross-chain token transfers without wrapping or liquidity pools, and ONFT for NFTs. LayerZero supports over 120 blockchains including EVM-compatible chains, Solana, Aptos, and others, enabling developers to unify liquidity and state across diverse ecosystems.

LayerZero differentiates itself by offering a secure, decentralized alternative to traditional cross-chain bridges that rely on fixed validator sets vulnerable to attacks. Its design allows developers to customize security per message by selecting decentralized verifier networks, ensuring censorship-resistant message delivery. The protocol’s immutability guarantees long-term reliability, while its composable architecture simplifies building complex omnichain dApps. Notable integrations include DeFi projects like PancakeSwap, Radiant Capital, and Stargate, which leverage LayerZero for omnichain token standards and liquidity transport.

Developers can get started quickly using LayerZero’s comprehensive documentation and open-source SDKs. The protocol supports Solidity, Rust, and Move languages for various chains. Key setup steps include deploying or integrating with Endpoint contracts, implementing OApp interfaces for message handling, and optionally running DVNs or Executors to participate in network security. LayerZero’s active community and developer support channels on Discord and Telegram provide additional resources for onboarding and troubleshooting.
