Axelar is a cross-chain interoperability network that connects blockchain ecosystems, enabling secure and seamless communication between different blockchains. Built with Cosmos SDK, Axelar allows decentralized applications (dApps) to interact across chains without compromising security or decentralization. Through its General Message Passing (GMP) and Axelar Bridge, developers can create scalable, cross-chain dApps and manage assets across multiple networks.
