The i2p outproxy is simply a user-specified proxy that i2p uses when you try to fetch someting outside the i2p network. I2p does not implement that proxy itself, therefore it is not part of i2p / it can’t be called an i2p exit node.

There are no exit nodes on i2p.

I’ll try qbittorrent too, just I was attracted to XD as it only supports i2p and it therefore claims it can have no ip leaks (ik that probably doesn’t mean qbittorrent is insecure). I guess the only way would be to upload to the torrent tracker, thanks!

Yeah the thing is that transmission sadly does not support using a proxy (therefore no i2p/changing to i2p trackers) so that sadly would not work (except if I got it wrong). Adding the torrent link as-is would not work through an i2p client as it only supports torrents inside the i2p network, and the torrents I have are from clearnet (can I add the torrent file, though?). Sorry if I do not make any sense, but thanks I’ll try it out anyway!
