Users can purchase advertising board as per their needs to promote their products, services, events, and more. All processes are carried out conveniently and safely through JEFFWorld.

### User Bidding System (TBA)

Users can purchase the rights to advertising spaces (with a limited duration) by participating in the bidding system and spending $JEFF. All auction processes are managed through Smart Contracts, and at the end of the auction, the highest bidder receives the advertising NFT that grants them the rights to the respective advertising board.

* Check the past auction history, which is managed on the blockchain.
* Send the desired bid amount in $JEFF.(Notifications are sent when the highest bid is updated.)
* When the auction concludes, the advertising NFT is transferred to the highest bidder.
