Here you can keep track of, and pay for the auctions you've won.
It's very easy - you just need to press the pay now button and then submit the transaction via your wallet.
After your transaction has been confirmed - you will own the NFT and the seller will get paid!
You made a commitment to pay if you won when you placed a bid - so if you don't want to pay the seller can flag your account for not paying.
Each time you get flagged for not paying - you won't be able to place a bid on any other items for 3 days.
If you get flagged 3 times - you won't be able to place a bid on any item ever again. You will only be able to buy items directly.
