Is there kind of a list of the federations already available for testing ?

Out of your "discover feature" (from which I can only see one mint recommended by  nostr:npub1t0nyg64g5vwprva52wlcmt7fkdr07v5dr7s35raq9g0xgc0k4xcsedjgqv by the way, I don't know if it's normal), is there another way of finding federations for testing ?

Thanks and congrats for the work !
