This enables secure private messaging, group communication, and application-specific channels. XMessenger also supports cross-chain messaging, enabling secure communication between users and applications across different blockchain networks. Deployment follows a privacy-first rollout strategy, including controlled testing, progressive mainnet activation, and continuous monitoring and optimization. --- # Agent Instructions This documentation is published with GitBook.
