 Some available transports are:

-- [@libp2p/webrtc-star](https://github.com/libp2p/js-libp2p-webrtc-star)

 - [@libp2p/webtransport](https://github.com/libp2p/js-libp2p-webtransport) (Work in Progress)
 
-If none of the available transports fulfills your needs, you can create a libp2p compatible transport. A libp2p transport just needs to be compliant with the [Transport Interface](https://github.com/libp2p/js-interfaces/tree/master/src/transport).
