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.
