 Development and maintenance is proudly sponsored by [Element](https://element.io). Element uses the SDK in their flagship [web](https://github.com/element-hq/element-web) and [desktop](https://github.com/element-hq/element-desktop) clients.
 
 The SDK is also the basis for multiple Matrix projects and we welcome contributions from all.
