Great question.

WebRTC still relies on STUN and, when direct connectivity isn't possible, TURN for ICE.

SecureBitChat currently supports ^Direct Mode^, where users exchange the SDP manually (copy/paste, QR code, file, etc.). Once exchanged, the peers establish a direct WebRTC connection.

Right now, users can configure their own STUN and TURN servers directly in the settings, use public servers, or any infrastructure they trust. An optional assisted connection mode is currently in development.
