RedeemMaster

RedeemMaster is a lightweight, dependency-free referral and milestone reward framework built for Minecraft 1.21+ networks running Paper, Purpur, or Spigot.

Instead of hard-coding economy or crate plugin APIs, RedeemMaster executes configurable console commands using placeholder tokens (<player>, <owner>, <count>). This lets you trigger rewards across any economy, token, or crate plugin (Vault, EssentialsX, PlayerPoints, ExcellentCrates) without needing additional soft-dependencies.

⚡ Key Features

• Zero External Dependencies: Native JVM execution that dispatches rewards directly via server console commands.
• Dual-Layer Anti-Alt Protection:
  • IP / Subnet Lock: Prevents players on the same network or IP from claiming each other's referral codes.
  • Playtime Requirement Gate: Validates active gameplay time using native statistics (PLAY_ONE_MINUTE) before allowing code redemptions.
• Flexible Reward Engine:
  • Referee Rewards: Starter packages given to the newcomer upon code usage.
  • Linear Owner Rewards: Fixed payouts given to the code owner for every referral.
  • Milestone Rewards: Supports both cyclic triggers (EVERY_X, e.g., every 5th invite) and one-time static milestones (EXACT, e.g., 25th invite).
• High-Performance Caching: Uses inverted UUID hash maps for O(1) runtime code lookups backed by simple flat-file YAML storage (invite.yml).
• Geyser & Floodgate Support: Compatible with Bedrock player prefixes (e.g., .PlayerName) and offline UUID tracking.
