 About

Matter (formerly Project CHIP) creates more connections between more objects,
simplifying development for manufacturers and increasing compatibility for
consumers, guided by the Connectivity Standards Alliance.

 What is Matter?

Matter is a unified, open-source application-layer connectivity standard built
to enable developers and device manufacturers to connect and build reliable, and
secure ecosystems and increase compatibility among connected home devices. It is
built with market-proven technologies using Internet Protocol (IP) and is
compatible with Thread and Wi-Fi network transports. Matter was developed by a
Working Group within the Connectivity Standards Alliance (Alliance). This
Working Group develops and promotes the adoption of the Matter standard, a
royalty-free connectivity standard to increase compatibility among smart home
products, with security as a fundamental design tenet. The vision that led major
industry players to come together to build Matter is that smart connectivity
should be simple, reliable, and interoperable.

Matter simplifies development for manufacturers and increases compatibility for
consumers.

The standard was built around a shared belief that smart home devices should be
secure, reliable, and seamless to use. By building upon Internet Protocol (IP),
Matter enables communication across smart home devices, mobile apps, and cloud
services and defines a specific set of IP-based networking technologies for
device certification.

The Matter specification details everything necessary to implement a Matter
application and transport layer stack. It is intended to be used by implementers
as a complete specification.

The Alliance officially opened the Matter Working Group on January 17, 2020, and
the specification is
available
for adoption now.

 Project Overview

 Development Goals

Matter is developed with the following goals and principles in mind:

Unifying: Matter is built with and on top of market-tested, existing
technologies.

Interoperable: The specification permits communication between any
Matter-certified device, subject to users’ permission.

Secure: The specification leverages modern security practices and protocols.

User Control: The end user controls authorization for interaction with
devices.

Federated: No single entity serves as a throttle or a single point of
failure for root of trust.

Robust: The set of protocols specifies a complete lifecycle of a device —
starting with the seamless out-of-box experience, through operational protocols,
to device and system management specifications required for proper function in
the presence of change.

Low Overhead: The protocols are
