From 2ee48da06449e3941ef0ba43494f73ef14c24e93 Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 1 Apr 2026 21:09:12 +0000 Subject: [PATCH 01/22] feat: add WebRTC voice/video call infrastructure MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements P2P calling over Nostr relays using WebRTC for media transport and NIP-59 Gift Wraps for encrypted signaling. No custom server required — only public STUN servers for NAT traversal. Protocol layer (quartz/nip100WebRtcCalls): - 6 new event kinds (25050-25055): offer, answer, ICE candidate, hangup, reject, renegotiate - WebRtcCallFactory for creating and gift-wrapping signaling events - CallIdTag and CallTypeTag for event metadata - Events registered in EventFactory Call state machine (commons/call): - CallState sealed interface with full lifecycle states - CallManager orchestrating signaling and state transitions - Follow-gate spam prevention: only followed users can ring, non-follows are silently ignored Android WebRTC integration (amethyst/service/call): - WebRtcCallSession wrapping Google WebRTC PeerConnection - CallForegroundService for keeping calls alive in background - IceServerConfig with default public STUN servers - User-configurable TURN server support Android UI (amethyst/ui/call): - CallScreen with offering, connecting, connected, and ended states - IncomingCallUI with accept/reject buttons - ConnectedCallUI with mute, video toggle, speaker, and timer - Call button added to 1-on-1 DM chat header - ActiveCall route added to navigation https://claude.ai/code/session_017hZm7yu7CzmcQgZGSaqSXS --- amethyst/build.gradle | 3 +

From: Claude Date: Wed, 1 Apr 2026 23:23:45 +0000 Subject: [PATCH 06/22] refactor: observe call events from LocalCache instead of EventProcessor MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Remove callManager injection from EventProcessor — let the existing gift wrap pipeline consume and index call events normally. Instead, observe new notes from LocalCache.live.newEventBundles in AccountViewModel and route call signaling events to CallManager from there.

-`draft` `optional` - -This NIP defines a protocol for establishing peer-to-peer voice and video calls between Nostr users using WebRTC, with Nostr relays serving as the signaling transport. - -## Motivation - -Nostr users currently lack a way to make real-time voice or video calls without relying on centralized services. By using Nostr relays for WebRTC signaling and public STUN servers for NAT traversal, calls can be established in a fully decentralized manner — no custom server infrastructure is required. Once a WebRTC peer connection is established, the relay is no longer involved in the media stream. - -## Overview - -The protocol works as follows: - -1. **Caller** creates a signed call offer event containing an SDP offer -2. The event is **gift-wrapped** ([NIP-59](https://github.com/nostr-protocol/nips/blob/master/59.md)) and published to relays -3. **Callee** unwraps the event, verifies the signature, and decides whether to accept -4. If accepted, callee sends back a gift-wrapped call answer event containing an SDP answer -5. Both parties exchange **ICE candidates** as gift-wrapped events for NAT traversal -6. A **direct WebRTC peer connection** is established for audio/video - -All signaling events MUST be gift-wrapped using [NIP-59](https://github.com/nostr-protocol/nips/blob/master/59.md) for metadata privacy.

Calls from non-followed users SHOULD be silently ignored. -- **Rate limiting**: Clients SHOULD ignore duplicate call offers from the same pubkey within a short window. -- **Expiration enforcement**: Clients MUST check the `expiration` tag and discard signaling events that have expired. - -## NAT Traversal - -This NIP does not mandate specific STUN or TURN servers. Clients SHOULD: - -- Ship with a default set of public STUN servers (e.g., `stun:stun.l.google.com:19302`) -- Allow users to configure custom TURN servers for restrictive network environments -- Use trickle ICE (sending candidates as they are discovered) rather than waiting for all candidates before sending the offer/answer - -## Implementation Notes - -- The `call-id` tag MUST be a UUID that is unique per call session. All signaling events for the same call share the same `call-id`. -- Events SHOULD have short expiration times (~5 minutes) since signaling data is ephemeral and has no long-term value. -- Clients SHOULD implement a ringing timeout (e.g., 60 seconds). If no answer is received, the call transitions to a "timed out" state. -- Clients SHOULD use a foreground service or equivalent mechanism to keep calls active when the app is backgrounded. -- The WebRTC `PeerConnection` SHOULD use Unified Plan SDP semantics. -- Clients MAY support call renegotiation (kind 25055) for toggling video on/off mid-call without tearing down the connection. - -## References - -- [NIP-01: Basic Protocol](https://github.com/nostr-protocol/nips/blob/master/01.md) — Event structure -- [NIP-31: Alt Tag](https://github.com/nostr-protocol/nips/blob/master/31.md) — Human-readable event descriptions -- [NIP-40: Expiration](https://github.com/nostr-protocol/nips/blob/master/40.md) — Event expiration timestamps -- [NIP-44: Encryption](https://github.com/nostr-protocol/nips/blob/master/44.md) — XChaCha20-Poly1305 encryption -- [NIP-59: Gift Wraps](https://github.com/nostr-protocol/nips/blob/master/59.md) — Encrypted event delivery -- [WebRTC Specification](https://www.w3.org/TR/webrtc/) — Peer-to-peer real-time communication -- [RFC 8445: ICE](https://datatracker.ietf.org/doc/html/rfc8445) — Interactive Connectivity Establishment -- [nostr-protocol/nips#771](https://github.com/nostr-protocol/nips/issues/771) — WebRTC signaling discussion diff --git a/quartz/src/commonMain/kotlin/com/vitorpamplona/quartz/nip100WebRtcCalls/WebRtcCallFactory.kt b/quartz/src/commonMain/kotlin/com/vitorpamplona/quartz/nip100WebRtcCalls/WebRtcCallFactory.kt deleted file mode 100644 index 858c5b5913..0000000000 --- a/quartz/src/commonMain/kotlin/com/vitorpamplona/quartz/nip100WebRtcCalls/WebRtcCallFactory.kt +++ /dev/null @@ -1,113 +0,0 @@ -/* - * Copyright (c) 2025 Vitor Pamplona - * - * Permission is hereby granted, free of charge, to any person obtaining a copy of - * this software and associated documentation files (the "Software"), to deal in - * the Software without restriction, including without limitation the rights to use, - * copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the - * Software, and to permit persons to whom the Software is furnished to do so, - * subject to the following conditions: - * - * The above copyright notice and this permission notice shall be included in all - * copies or substantial portions of the Software. - * - * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR - * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS - * FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

ICE candidate buffering: Candidates arriving before the WebRTC session exists (callee ringing) or before remote description is set (caller waiting for answer) are now queued in pendingIceCandidates and flushed once setRemoteDescription is called. This was the root cause of calls getting stuck at "Connecting" — ICE candidates were silently dropped. 2. Stale event filter: All signaling events older than 30 seconds are discarded in CallManager.onSignalingEvent() to prevent old cached events from triggering phantom calls. Also: removed cleanup() from WebRTC onDisconnected callback to avoid double-cleanup race with the CallManager state observer. https://claude.ai/code/session_017hZm7yu7CzmcQgZGSaqSXS ---
