ezAuctions

You can hover over the item name to show a tooltip with all item enchants, durability, and other item information stored in NBT.

Sealed auctions can be enabled/disabled and allow auctions to be made without the bids being disclosed until the end.

Players can specify an autobuy at which the auction will immediately end.

Here you can see both the item name and all numbers are formatted in Arabic. The number formatting can be defined in the messages.properties following MiniMessage formatting standards. The item name is formatted based on the player's language.

You can use advanced chat formatting features such as gradients using MiniMessage.
