Frozenkeyall

FrozenKeyall is a lightweight but powerful PaperMC plugin that automatically rewards all online players with configurable commands (crate keys, money, items — anything) after a repeating timer cycle.
Every player has their own personal countdown timer that persists across restarts and disconnects — progress is saved by UUID, so rejoining players resume exactly where they left off. Only players who complete their cycle while online receive the reward, preventing any timing abuse.
Features:

• Per-player persistent timer (UUID-based, survives restarts & reconnects)

• Fully configurable reward commands with {player} placeholder

• Full color support — MiniMessage, HEX &#RRGGBB, gradients & legacy & codes

• Optional broadcast message when a player receives their reward

• PlaceholderAPI support — %frozenkeyall_timer% for scoreboards & TAB

• Instant cycle restart — no gap between reward rounds

• Configurable sounds on reward & timer check

• Folia-aware scheduling (compatible with Paper 1.21–1.21.8)

• Admin commands: /keyall check, reset, give, reload, debug

• Async auto-save to prevent data loss on crashes

Dependencies: PlaceholderAPI (optional)
Compatibility: Paper / Folia 1.21 – 1.21.8
