This is proof-of-concept P2P NFT Marketplace.
It benefits from being decentralized and therefore highly available, auditable and with predictable rules and costs.
It's made out of fun allowing buyers to bargain over a reference price published by the seller.
An auction is created by the owner of the NFT using the put_listing entrypoint and bids are put in through put_offer requiring a transaction value to be locked. In case the offer is not accepted, a bid might be cancelled with withdraw_offer and the seller might give up the auction by cancel_listing.
A trade is concluded when a seller accepts the highest bid with accept_offer.
For every change on an auction state, an event is emitted allowing the ae_mdw to track all operations.
