What SellChest Solves

On most servers, making money means manual farming, constant shop clicking, or standing at farms. Players waste time selling items one by one instead of doing what they love - playing.

SellChest fixes that. Place a chest and it sells your items automatically. Every chest has three independent upgrade paths you develop in real-time through an interactive GUI. More items per cycle, faster selling, higher price percentage. Every parameter is fully configurable in a dedicated YAML file.


Three Upgrade Paths

Three independent upgrade lines per chest: Items Amount Sell Frequency Price Percentage
Every value is fully configurable in upgrades.yml - add unlimited levels.

· · · ITEMS AMOUNT · · ·

Level 1 1 item per cycle - free
Level 2 2 items per cycle - $1,000
Level 3 4 items per cycle - $2,500
Level 4 8 items per cycle - $5,000
Level 5 16 items per cycle - $10,000
Level 6 32 items per cycle - $25,000
Level 7 (MAX) 64 items per cycle - $50,000

· · · SELL FREQUENCY · · ·

Level 1 Every 10 minutes - free
Level 2 Every 8 minutes - $1,500
Level 3 Every 5 minutes - $4,000
Level 4 Every 3 minutes - $10,000
Level 5 Every 2 minutes - $25,000
Level 6 (MAX) Every 1 minute - $50,000

· · · PRICE PERCENTAGE · · ·

Level 1 50% item value - free
Level 2 60% item value - $2,000
Level 3 70% item value - $5,000
Level 4 80% item value - $15,000
Level 5 90% item value - $35,000
Level 6 (MAX) 100% item value - $75,000

Server Networks MySQL support for centralized databases. PlaceholderAPI for ranking and scoreboard integration.
RPG Servers SellChests as dungeon or quest rewards. Upgrades as a character progression system.
