Q: Does WebRTC use TCP or UDP as its peer-to-peer transport?
A: It can use either. By default, preference is given to UDP, but depending on the firewall(s) in between the peers connecting it may only be able to connect with TCP.
That is UDP or (if UDP is not possible) TCP.
Or is there something else you wanted to know?

Answer 2

WebRTC is built on top of several protocols:
STUN, ICE, DTLS, SDP, SRTP, RTCP
All of these protocols are used to transfer a stream from one peer to another.
