🌌 UniRedeem

The Ultimate Universal Redeem Code Plugin for Minecraft networks. Developed with ❤️ by the Univolve team.

UniRedeem is a modern, high-performance, multi-platform redeem code solution. It is built from the ground up to support Spigot, Paper, Purpur, Folia, BungeeCord, and Velocity networks concurrently using a single Universal Jar supporting Minecraft 1.13 through 26.2+ (Chaos Cubed).

✨ Features

• ⚡ Multi-Platform (Universal Jar): Single .jar file that runs seamlessly on Spigot, Paper, Purpur, Folia, BungeeCord, and Velocity.
• 🌟 Verified Minecraft 26.2 Support: Built with forward-compatible abstractions verified on Minecraft 26.2 (Chaos Cubed) and older versions down to 1.13.
• 🎮 In-Game Admin GUI: Interactive 54-slot chest interface (/uniredeemadmin gui) to view, manage, and revoke active codes with one click.
• 📦 Batch / Bulk Code Generator: Generate dozens of unique giveaway keys in one command with /uniredeemadmin generatebatch.
• ⌨️ Intelligent Tab-Completion: Full auto-completion for all player and administrative commands across all platforms.
• 🛡️ Anti-Spam & Rate Limiting: Built-in cooldowns (general.cooldown-seconds) to prevent brute-force code guessing.
• 🔒 Anti-Alt & IP Protection: Optional IP address validation to block players from claiming one-time codes on alternate accounts.
• 🌐 Discord Webhooks: Real-time Discord notifications and embeds for redemptions and admin actions.
• 🔊 Audio & Visual Feedback: Configurable sound effects (ENTITY_PLAYER_LEVELUP) and on-screen Titles/ActionBars.
• 💾 Dual-Storage Engine: SQLite (local zero-setup) and MySQL/MariaDB (network synchronization) powered by high-performance HikariCP connection pooling.
• 🔑 Limitation & Expiry System:
  • Max Global Uses: Limit how many times a code can be claimed globally.
  • Max Uses Per Player: Restrict claims per user (e.g. one-time use codes).
  • Expiration (Time-Limits): Expiry dates or countdown durations from code generation.
  • Permission Node Requirement: Require players to hold specific permissions to claim a code.
• ⚙️ Multicontext Multi-Command Rewards: Run multiple commands per code across different execution contexts:
  • [CONSOLE] - Executed by console on the local server.
  • [PLAYER] - Executed by the player redeeming the code.
  • [PROXY] - Forwarded via Plugin Messaging and executed on the Proxy console (BungeeCord/Velocity).
• 🌐 Embedded HTTP REST API Server: Connect your website, Discord bot, or store portal using a secure Bearer token JSON API.
• 🧩 Extensive Placeholders: Supports local placeholders and registers natively with PlaceholderAPI (on Bukkit/Paper).

🛠️ Commands & Permissions
