What is layerzero-v2?

layerzero-v2 is an omnichain interoperability protocol for blockchain applications that need to exchange messages across blockchains. It uses contracts, decentralized verifier networks, and Executors to verify and deliver cross-chain messages. The repository primarily uses Rust, TypeScript, JavaScript, and shell files, with Move identified as its primary language.

Key features of layerzero-v2

  • LayerZero V2 provides Solidity contract standards for sending arbitrary data, tokens, and external calls to multiple chains.
  • Applications can configure decentralized verifier networks to verify cross-chain messages.
  • Executors abstract destination gas and automatically deliver messages on behalf of the source sender.
  • The OApp Standard provides a generic interface for sending and receiving arbitrary data between contracts on different blockchain networks.
  • The OFT Standard supports fungible-token transfers across multiple blockchains without asset wrapping or middlechains.

How layerzero-labs/layerzero-v2 works

Applications use contracts in /oapp to send and receive arbitrary data between contracts on different blockchain networks. The OApp Standard provides the generic message-passing interface, while the OFT Standard supports fungible-token transfers across blockchains. Core immutable protocol interfaces, including the LayerZero Endpoint, are in /protocol. Contracts in /messagelib provide append-only on-chain MessageLib implementations and reference communication between DVNs, Executors, and Ultra Light Nodes. DVNs verify cross-chain messages, and Executors deliver them on destination chains while abstracting destination gas for a fee.

How does layerzero-v2 work?

layerzero-v2 uses application contracts, DVNs, MessageLibs, and Executors to send, verify, and deliver cross-chain messages. The protocol interfaces are in /protocol, application standards are in /oapp, and MessageLib contracts are in /messagelib.

How do I install layerzero-v2?

layerzero-v2 can be installed, built, and tested with yarn && yarn build && yarn test.

What language is layerzero-v2 written in?

layerzero-v2 is primarily identified as a Move project. Its files also include Rust, TypeScript, JavaScript, and shell code.

How is the layerzero-v2 code organized?

layerzero-v2 places most code under packages. The /oapp directory contains application standards, /protocol contains core protocol interfaces, and /messagelib contains MessageLib contracts.

Who is layerzero-v2 for?

layerzero-v2 is for developers building blockchain applications that send messages, tokens, or external calls across multiple blockchain networks. It also supports custom DVNs and Executors.

Repowise built this map of layerzero-labs/layerzero-v2 from its source and git history. It parses every symbol, draws the dependency graph, scores each file's health from complexity, duplication, coverage and churn, finds hotspots and owners in the history, and writes documentation for every module. Your coding agent reads the same index over MCP, so its answers cite real files.
