ServerTrades

Safe, direct player-to-player item trading for Paper/Purpur 26.3. One player runs /trade <player>, the other accepts, and both open a shared trade GUI where they place items, confirm, and swap atomically.

ServerTrades is built around dupe-safety: every trade click is cancelled and item movement is handled manually, so items live in the trade session — never on the cursor — and are delivered or returned exactly once.

Features

• Request flow — /trade <player> sends a request; the target accepts or denies. Configurable request timeout and cooldown.
• Dual-confirmation GUI — both players place up to a configurable number of items, mark ready, and a countdown runs before the atomic swap.
• Trade chat — a private per-trade chat channel toggled in-GUI or via /trade chat.
• Item blacklist — block trades by material and, optionally, by lore patterns (e.g. "Soulbound", "Untradeable").
• Requests toggle — players can turn incoming trade requests off with /trade toggle.
• Background timeout — if a player closes the trade GUI, a timer (with reopen support) protects the session before it auto-cancels.
• Interrupted-trade persistence — items from trades interrupted by a crash/quit are stored to disk and returned safely.
• Optional CombatLOG integration — block or cancel trades while players are PvP-tagged (skipped if CombatLOG is absent).
• Optional PlayerSettings integration — per-player language.
• Configurable distance limit, sounds, and MiniMessage-styled GUI.
