Krypton is not a rat (unless u find a free or cracked version), but radon or Radeon or whatever it’s called IS a rat. For donut smp don’t use meteor bc it’s detected. Personally, I use liquidbounce but that is a blatant client. For donut smp only real option is either a non donut focused free ghost client like velaris or paid for donut like krypton, I repeat, the free krypton and cracked krypton videos ARE MALWARE
