Accepting an Offer
To accept an offer on your item, navigate to the NFT page.
Click the Offers tab, and you can see all the offers to your NFT.
Click the Accept button on the offer which you would like to accept.
You will see a request pop up with two steps, Step 1: Approval and Step 2: accept offer. The approval step is a one-time only action for each collection, unless you revoke the approval later on.
Once you've approved the collection, the request will automatically jump to Step 2 requesting a transaction. The NFT will be transferred to you when the transaction is confirmed.
