We’re slowly starting to release a stable version out. In the tutorial that we wrote at WebSockets 🔌 on the Internet Computer: Getting Started | by Luca Bertelli | Medium you can find all the details to get started using the IC WebSocket integration.
Motoko CDK will follow.
The WebSocket Gateway can now be considered trustless as it cannot tamper, reorder or block the messages without being detected by both the client and the canister. We’re waiting for the vetKeys to become generally available to integrate them into our libraries and make sure the Gateway can’t even read the messages.
Let us know if you need any further help.
