Steps to Make an Offer:

Create Offer: The user can create an offer by calling the createOffer API. This API will fetch the Solana NFT asset information that is required to initiate a signature in the Phantom or Backpack wallet.

Description: Fetches the relevant Solana NFT details and prepares the offer for signing.
Sign the Offer: After calling the createOffer API, the user will be prompted to sign the transaction using their Phantom or Backpack wallet.

Submit Proof of Offer: Once the transaction is signed successfully, the user will need to confirm the transaction via the submitProofOfOffer API. This will finalize the offer and create an offer order for the token owner.

API Request: submitProofOfOffer
Description: Confirms and submits the offer transaction to the token owner.
