Sellers put intelligence up for sale by conducting auctions. Arkham Intel Marketplace auctions will follow the same paradigm as auctions on NFT marketplaces, where sellers can set a purchase price, minimum bid, and length of auction. Once the seller submits an auction post, the intelligence is verified by Arkham before the auction begins. To prevent spam, auction holders stake 10 ARKM with their submission, which is lost if the submission is rejected. Auctions, like bounties, have a 15 day lock-up before a winning bid can be withdrawn from the auction smart contract, but auctioneers can withdraw early for a 10% fee.
