Ability to inventory items to other players

hello so a general idea that i have is most inventory items stored in the player’s account that the player does not use could be usefull as a better option to gain SL or GE depending on the item

for example i do have a lot of wagers and orders left overs to sell them for SL depends on the player’s value selling choice by implementing a kind of similar built in Store but in trade of GE or SL

kinda similar system like on CrossOut but with that diffrence
