Glacis is a versatile protocol serving as a Firewall, Router, and universal adaptor for chain-agnostic messaging, facilitating seamless cross-chain operations. Developers utilize Glacis to define security requirements and routing logic for messages sent across different blockchain networks, enabling simplified and secure decentralized application (dApp) development. By integrating with cross-chain General Messaging Passing protocols (GMPs) like Axelar and Wormhole, Glacis empowers developers to focus on creating robust applications without the complexities of managing multiple blockchain networks.
