UndyingSmp is a whitelisted Lifesteal Challenge Minecraft server where players compete for a $100 prize. The server is cross-play compatible, has a 50 member max (probably), and offers features like TPA, manual and automatic anti-cheat detection, DeathCoords upon death, and EnderDragonEggTracker for tournament challenges. It also has custom villages with shops and uses the BetterSleeping plugin. To get added to the whitelist, you must join the UndyingSmp Discord. Once there, read the rules entirely from top to bottom to learn what to do next.
