Proposal for a User-Created Emoji/Sticker Trading System

I’d like to share one of my ideas for expanding the Town ecosystem.
Most chat platforms offer features like paid emojis and stickers, but users usually have to pay the platform directly or subscribe to a monthly plan just to use them for a limited time.
However, in Town, I believe it could be possible for users to create their own emojis and stickers based on their ideas, set prices freely instead of sticking to a fixed price model like other apps, and trade them freely on-chain.
If this system were implemented, it could make Town chats much more lively and expressive, leading to a more active and vibrant community overall.
What do you think about this idea?
