Messaging without an operator. Owned by its community.

OpenChat is a new paradigm in digital communication, built from the ground up on the Internet Computer Protocol. Unlike traditional messaging platforms — which rely on centralized servers and harvest user data — OpenChat operates entirely on-chain, giving users complete control over their conversations and personal information.

It combines the familiar experience of modern messaging apps with the security and decentralization benefits of running on a network protocol. Every message, group, and user profile is stored on-chain, creating a transparent and tamperproof communication network that cannot be shut down or censored by any single entity.

OpenChat leverages the Internet Computer to deliver a messaging experience that rivals centralized platforms in speed and usability, while providing security guarantees those services cannot match.

Getting started

Visit oc.app and sign in with Internet Identity — the decentralized identity system that eliminates the need for passwords. Once authenticated, you can immediately start messaging, create groups, and explore the platform’s features. No downloads, no browser extensions, no account creation forms required.

Features and capabilities

OpenChat supports both private one-on-one conversations and group chats, with reactions, file sharing, and rich media. The platform also includes built-in cryptocurrency functionality — send and receive tokens directly inside a conversation to split bills, send tips, or run peer-to-peer transactions.

OpenChat’s on-chain architecture provides several key advantages over traditional messaging platforms. By storing all data on the Internet Computer, it ensures that conversations cannot be deleted by platform administrators, messages cannot be intercepted by third parties, and the service cannot be shut down by corporate or government entities.

Integration with Internet Identity provides a seamless, password-free authentication experience. The identity is cryptographically secured and works from any device using biometric authentication or security keys — eliminating password-based attacks and providing a consistent experience.

Built-in crypto payments

The chain-key engine that powers the Internet Computer enables OpenChat to transfer real value alongside messages — splitting a restaurant bill, sending a tip, or conducting a business transaction — all secured by the network’s tamperproof infrastructure.

A developer-friendly platform

For developers, OpenChat is an open platform for building messaging experiences. The on-chain architecture means integrations, bots, and extensions can interact directly with OpenChat’s canisters, opening up new possibilities for decentralized communication applications.

Community-driven development

OpenChat is continuously evolving. Its decentralized governance model ensures that the community has a voice in development, making OpenChat a genuinely community-driven messaging platform.
