LayerZero Labs

Develops interoperability protocol for blockchains

About LayerZero Labs

LayerZero develops an interoperability protocol that connects over 50 different blockchains, allowing developers to create applications, tokens, and experiences that work across multiple chains. Their technology includes immutable on-chain endpoints, a configurable Security Stack, and a permissionless set of Executors, which enable the transfer of messages and assets between blockchains without censorship. This platform is tailored for developers and organizations in the blockchain and cryptocurrency sectors, providing them with the tools to define their own security and efficiency configurations. Unlike competitors, LayerZero focuses on seamless blockchain interoperability, facilitating the transfer of assets like tokens between chains, as seen with Curve Finance and Uniswap. The goal of LayerZero is to enhance the development and functionality of omnichain applications, making it easier for developers to build across various blockchain networks.
