Axelar is a decentralized cross-chain communication network, aiming at leveling up interoperability in Web3 by connecting heterogeneous blockchains and enabling asset mobility and program composability in an optimized way for both builders and end-users. Axelar consists of two layers: the network and the API above it. At Axelar’s core is a permissionless overlay network that delivers Turing-complete cross-chain communication via proof-of-stake and permissionless protocols. Sitting on top of the network are APIs and protocols, an application-development layer that developers use to compose across any number of chains. Once integrated, all new interconnected blockchains automatically become interoperable with the application, enabling limitless network effects.
