LayerZero is a cross-chain messaging protocol that connects blockchains like Ethereum, Solana, Base, Arbitrum, Avalanche, Optimism, and Polygon. Instead of locking and minting wrapped assets in the traditional bridge model, it allows smart contracts to send verified messages across chains, enabling applications to function seamlessly in multiple ecosystems. This architecture powers omnichain tokens (OFTs), NFTs (ONFTs), governance systems, and unified liquidity designs.
LayerZero uses a configurable security model built around independent verification components (commonly oracles and relayers) to validate cross-chain messages. This separation prevents a single point of failure and allows applications to choose their own trust assumptions. Developers can tailor their security stack depending on the sensitivity and value of their application.
